Feature deep-dive
Your Personal YouTube Video Library
YouTube gives you Watch Later and your history. That is it. No categories, no timestamps, no notes, no search. YouTube Bookmark Pro replaces all of that with a real library - one that saves every video you care about, organizes it your way, and lets you find anything in milliseconds. Twenty features, zero monthly cost for the core library. This page walks through every single one.
Why you need a YouTube video library
The average YouTube user watches over 40 minutes of video per day. Over a year, that adds up to hundreds of hours and thousands of individual videos. Some of those videos contain information you will need again - a tutorial that explained a concept perfectly, a lecture that changed your perspective, a cooking demo you want to try next weekend. But YouTube was not designed to help you find them later.
Watch Later is a flat list with no search. History disappears after 36 months (or sooner if you have auto-delete turned on). Liked Videos is just another flat list. Playlists require manual management and have no note-taking capability. If you have ever spent 15 minutes scrolling through your history trying to find that one video about CSS Grid layouts, you already know the problem.
YouTube Bookmark Pro solves this by giving you a dedicated video library inside the YouTube interface. It sits in a side panel, captures videos in one click, organizes them into categories and projects, attaches notes and timestamps, and lets you search across everything you have ever saved. The entire library feature set is free. Not freemium, not time-limited, not capped at 50 videos. Free, permanently, with no limits on the number of saves.
Below is a complete walkthrough of all twenty library features, grouped by workflow: how you capture videos, how you organize them, how you annotate them, how you find them, how you review them, and how you manage your data. Each feature includes a concrete use case so you can see exactly how it fits into a real workflow.
What the library looks like
Live replica of the extension side panel.
YouTube Bookmark Pro
The library lives in a side panel that slides open next to any YouTube page. At the top you see three tabs: Library, Subs, and Creator. The Library tab is where all your saved videos live, organized into category shelves. Each video card shows the thumbnail, title, channel name, duration, your note (if you added one), and any saved timestamp. The search bar at the top searches across everything instantly. The whole panel is designed to take up minimal screen space while keeping every important detail visible at a glance.
Group 1
Capture - Save videos your way
Saving a video should be faster than thinking about it. If the save process takes more than two seconds, you will skip it, and the video is lost to your history forever. YouTube Bookmark Pro gives you four different ways to save a video, each designed for a different moment in your workflow. Whether you are watching a video, browsing search results, or scanning your subscription feed, there is always a save path within reach.
Save Any Video in One Click
When you are watching a YouTube video, a save button appears in the extension side panel. Click it, and the video is captured instantly. The extension grabs the video title, channel name, total duration, current timestamp, and thumbnail automatically - you do not need to copy a URL or type anything. There is also a configurable keyboard shortcut (the default is Alt+S) for people who prefer to keep their hands on the keyboard. If you are watching a tutorial and the instructor says something important at the 14-minute mark, you press Alt+S and the video is saved with that exact timestamp. No interruption, no context switching, no opening a new tab to paste a link somewhere. The save action completes in under a second, and you see a brief confirmation toast before returning to your video.
Drag & Drop Saving
Not every video you want to save is one you are currently watching. Sometimes you are browsing your YouTube homepage, scanning search results, or scrolling through a channel's uploads. In any of these contexts, you can grab a video thumbnail and drag it directly into the YouTube Bookmark Pro side panel. As you drag, the panel highlights with a blue glow to confirm it is ready to receive the video. Drop it, and the video is saved with all its metadata captured automatically. This is particularly powerful when you are triaging a list of results - say you searched for "React Server Components tutorial" and got 20 results. You can quickly drag the three or four most promising ones into your library without watching any of them first, then come back later to work through them one by one. Drag and drop works on the homepage feed, search results, channel pages, playlist pages, and even the sidebar recommendations.
Auto-Open Save Modal
When you click the save button, a modal window opens automatically with the category selector and a note field. The category defaults to your most recently used category, so if you have been saving design videos all morning, the "Design" category is already selected. The note field is empty and focused, ready for you to type a quick reminder about why you saved this video. You might write "explains the box model with diagrams" or "skip to 8:30 for the API walkthrough." Adding this context takes three or four seconds, but it makes the video dramatically more useful when you search for it weeks later. If you do not want to add a note, just hit Enter or click Save and the video lands in your library with the selected category and no note. The modal is designed to add value without adding friction - it appears when you need it and gets out of the way when you do not.
Duplicate Protection
If you try to save a video that is already in your library, the extension catches it before the save completes. A warning appears telling you the video already exists, which category it is in, and when you originally saved it. This prevents the most common frustration with any bookmarking system: accidental duplicates. Without duplicate detection, you end up with the same CSS Grid tutorial saved three times in three different categories because you forgot you had already bookmarked it. YouTube Bookmark Pro eliminates that problem entirely. The detection works across all save methods - whether you use the save button, the keyboard shortcut, or drag and drop, the extension checks your library and warns you immediately. You can still choose to save the video again in a different category if that is what you want, but the decision is intentional rather than accidental.
Save to Library
The save modal captures everything in one step. The video title and thumbnail are pulled from YouTube automatically, and the timestamp reflects exactly where you were in the video. You pick a category from your existing list (or create a new one on the spot), add an optional note, and click Save. The entire flow takes under five seconds from the moment you decide to save a video to the moment it appears in your library. This is the core interaction loop of the library, and it is designed to be so fast that you never hesitate to save something.
Group 2
Organize - Structure that scales
A library without organization is just a pile. The first 20 videos you save will be easy to manage in a flat list. But once you hit 50, 100, 200 videos, you need structure. YouTube Bookmark Pro gives you two layers of organization - categories for broad topics and projects for goal-driven collections - plus drag-and-drop reordering and flexible sorting to keep everything where you need it.
Custom Categories
Categories are the primary organizational unit in your library. You create them, name them, and decide what goes where. A web developer might have categories like "CSS," "JavaScript," "DevOps," and "Career." A student might use "Organic Chemistry," "Linear Algebra," "History 201," and "Exam Prep." A home cook might create "Weeknight Dinners," "Baking," "Knife Skills," and "Meal Prep." There is no limit to the number of categories you can create, and each one appears as a visual shelf in your library with its own section header. You can rename categories at any time - if "Misc" becomes "Product Design," the videos inside stay put and the label updates everywhere. You can reorder categories so the ones you use most appear at the top. And if a category becomes irrelevant, you can delete it (the videos inside can be moved to another category first or deleted). Categories are simple by design because they need to scale from 3 categories to 30 without the system becoming complicated to use.
Projects
Projects are a second organizational dimension that works independently of categories. While categories group videos by topic (CSS, Cooking, Music), projects group videos by goal. If you are working on a website redesign, you might create a "Homepage Redesign" project and add videos from multiple categories: a CSS animation tutorial from your "CSS" category, a color theory video from your "Design" category, and a copywriting framework from your "Marketing" category. The project brings together videos that serve a common purpose, regardless of their topic. This is particularly useful for students working on research projects, creators planning content series, or anyone with a time-bound goal that draws on multiple areas of knowledge. Projects are separate from categories - adding a video to a project does not remove it from its category. You can archive completed projects and create new ones without affecting your underlying category structure. Think of categories as your permanent filing system and projects as your temporary workbenches.
Drag & Drop Reordering
Within any category, you can drag videos to rearrange their order. Put the most important tutorial at the top. Move a completed video to the bottom. Arrange a sequence of learning videos in the order you want to watch them. The drag interaction is smooth and immediate - grab a video card, drag it to the desired position, and release. A blue insertion indicator shows you exactly where the video will land. This also works across categories: if you saved a video in "Misc" but realize it belongs in "JavaScript," you can drag it from one category shelf to another. The whole reordering system is designed to work like arranging files on a desktop. No menus, no dropdown selectors, just grab and move. Your custom order is preserved across browser sessions, so the arrangement you set up on Monday is still there on Friday.
Sort Your Way
Beyond manual drag-and-drop ordering, each category has a sort control that lets you sort videos by four criteria: date saved (newest first or oldest first), channel name (alphabetical), video title (alphabetical), or video duration (shortest first or longest first). Each category remembers its sort preference independently, which means your "Learning" category can be sorted by date saved while your "Quick Tips" category is sorted by duration (shortest first, so you can knock out a quick video during a break). Changing the sort order is a single click on the sort icon, which cycles through the available options. Sort preferences persist across sessions. This is especially useful when you have a large category with 30 or 40 videos - sorting by channel name groups all videos from the same creator together, while sorting by duration helps you pick a video that fits the time you have available right now.
Group 3
Annotate - Add context that lasts
Saving a video is only half the value. The other half is the context you attach to it. Why did you save this? What was the key insight? Where in the video was the important part? YouTube Bookmark Pro gives you three annotation tools that turn a simple bookmark into a knowledge artifact: notes for your thoughts, timestamps for precision, and content flags for privacy.
Notes & Timestamps
Every saved video can have a text note attached to it. Notes are freeform - you can write a single word, a sentence, or a short paragraph. The most useful notes are specific: instead of "good video," write "explains the difference between margin and padding using the box model diagram at 7:14." Notes are fully searchable, which means your annotations become discovery paths. If you search for "box model" three months later, the video with that note surfaces immediately even though the video title says nothing about box models. Timestamps work alongside notes. When you save a video, the extension captures the exact position in the video where you clicked save. That timestamp appears on the video card as a clickable link - click it, and the video opens at that exact moment. You can also edit the timestamp manually after saving if you want to point to a different moment. The combination of notes and timestamps turns your library from a list of links into a navigable knowledge base. Instead of rewatching a 45-minute lecture to find the part about recursion, you click the timestamp and land exactly where you left off.
Sensitive Content Flags
Some videos in your library might be personal, sensitive, or simply not something you want visible on a shared screen. The sensitive content flag lets you mark individual videos so that when Privacy Mode is activated, those specific videos show masked titles and blurred thumbnails. This is different from Privacy Mode itself (which masks everything) - sensitive flags give you granular control over which videos get hidden. A therapist who saves mental health educational content might flag those videos so they do not appear during a screen share with colleagues. A student studying for a medical exam might flag anatomy videos. A creator researching competitors might flag those competitor videos. The flag is a simple toggle on each video card, and it only takes effect when Privacy Mode is turned on. When Privacy Mode is off, all videos display normally regardless of their flag status.
Right-Click Context Menu
Right-clicking on any saved video card opens a context menu with quick actions: edit note, change category, copy the YouTube link, open the video in a new tab, toggle the sensitive content flag, or delete the video from your library. This is the fastest way to manage individual videos without opening the full edit modal. If you are scanning through your "Learning" category and realize a video belongs in "JavaScript" instead, right-click, select "Change Category," pick the new category from the dropdown, and it moves instantly. If you want to share a video link with a friend, right-click and copy the link - it copies the full YouTube URL with the saved timestamp appended, so your friend lands at the exact moment you bookmarked. The context menu is keyboard-navigable, so you can right-click, arrow down to the action you want, and press Enter. Regular YouTube viewers who manage large libraries appreciate this because it eliminates the need to open, edit, and close individual video cards when making quick changes.
Group 4
Find - Search everything instantly
A library is only as good as its search. If you cannot find a video in under five seconds, the library has failed you. YouTube Bookmark Pro searches across every field in your library - titles, channels, notes, categories, and timestamps - and returns results as you type. No waiting for server responses, no loading spinners. The search is local and instantaneous.
Search & Filter Everything
The search bar at the top of the library panel accepts any text query. As you type, results filter in real time. Type "grid" and every video with "grid" in its title, channel name, note, or category appears. The matching text is highlighted in the results so you can see exactly why each video matched. Beyond text search, you can filter by category (show only videos in "Learning"), by date range (show only videos saved this month), or by watched status (show only videos you have not watched yet). These filters combine with text search, so you can search for "flexbox" within your "CSS" category to narrow results even further. The search index updates the moment you save or edit a video, so new saves are immediately searchable. For users with large libraries - 500 or 1,000 videos - the instant search is the feature that makes the library usable at scale. Without it, you would spend more time looking for videos than watching them.
Category Playback
Any category in your library can function as a playlist. Click the play button on a category header, and the first video in that category opens on YouTube. When it finishes (or when you click next), the second video in the category starts automatically. This turns your curated categories into sequential learning paths. If you have a "React Fundamentals" category with 12 videos arranged in a specific order, you can play through them like a course, starting from video one and working through to video twelve. Playback starts from the saved timestamp if one exists, so if you saved a video at the 14-minute mark because the first 14 minutes were introductory fluff, playback skips directly to the useful part. You can start playback from any video in the category, not just the first one. And the playback order respects your custom sort or drag-and-drop arrangement, so the videos play in exactly the sequence you set up.
Watch Progress Tracking
The library tracks which videos you have watched and which are still pending. When you open a saved video and watch it through (or watch past a configurable threshold, like 80% of the video's duration), the library marks it as watched. Watched videos get a subtle visual indicator - a small checkmark on the thumbnail and slightly muted text. This makes it easy to scan a category and see exactly where you left off. If you have a "Machine Learning" category with 15 videos, you can immediately see that you have watched 9 and still have 6 to go without having to remember or track it manually. You can also manually mark a video as watched or unwatched by right-clicking and toggling the status. The filter system lets you show only unwatched videos, which is useful when you sit down for a study session and want to see only the content you have not covered yet.
YouTube Bookmark Pro
Notice how search matches appear across different fields. The first result matches on the video title. The second matches on both the title and the note. The third matches on the title. Each match is highlighted in blue so you can immediately see why the video appeared. The results span multiple categories (Learning and Design), because search works across your entire library, not just the currently viewed category. With 147 videos in this library, the search narrowed to exactly three relevant results in real time as the user typed.
Group 5
Review - Stay on top of your saves
Saving videos is easy. Watching them is the hard part. Without a review system, your library becomes a graveyard of good intentions - hundreds of videos you saved and never returned to. YouTube Bookmark Pro includes three features specifically designed to keep you engaged with your saves: digest buckets that create urgency, privacy mode for shared environments, and a dedicated review view for browsing chronologically.
Daily Digest & Weekly Digest
The digest system is built around a simple behavioral insight: open-ended to-do lists never get done, but time-boxed tasks create action. When you save a video, it lands in a digest bucket. You can choose between daily and weekly digests. A daily digest bucket collects everything you save in a single day and gives you until the end of the next day to watch them. A weekly digest collects saves from an entire week and gives you until the following weekend. Each bucket shows a countdown timer - "2 days remaining" or "5 hours remaining" - so you always know how much time you have. When the timer expires, unwatched videos in that bucket are automatically pruned from the digest view (they remain in your main library, but the digest clears). This creates a natural cadence: save videos throughout the day, review the digest in the evening, and start fresh tomorrow. The pruning mechanism prevents the common failure mode where a "watch later" list grows to 500 items and becomes psychologically impossible to tackle. By keeping each digest bucket small and time-limited, the system stays manageable.
Privacy Mode
Privacy Mode is a single toggle that masks all video titles and thumbnails across your entire library. When activated, titles are replaced with bullet characters and thumbnails become solid gray rectangles. Channel names are also hidden. The library is still functional - you can navigate categories, scroll through videos, and even search (results appear masked) - but nothing on screen reveals what you have been watching. This is designed for three specific scenarios. First, screen sharing during work calls: you open the YouTube Bookmark Pro panel to demonstrate a feature to a colleague, and Privacy Mode ensures your personal viewing habits stay private. Second, working in public: at a coffee shop or library, you can browse your library without anyone over your shoulder seeing the content. Third, presentations: if you are showing your browser during a presentation or demo, Privacy Mode prevents your library from becoming a distraction. Toggle it on with one click, toggle it off with one click. There is no setup, no PIN, no complicated configuration.
Review Library
The review library is a dedicated view that shows your saves chronologically, separate from your organized category structure. While the main library view groups videos by category, the review view shows them by time: what you saved today, this week, this month, or earlier. This is useful for two workflows. First, catching up: if you saved 12 videos over the past week, the review view shows all 12 in the order you saved them, regardless of their categories. You can work through the list from top to bottom without jumping between category shelves. Second, auditing: if you want to review whether your recent saves are still relevant, the chronological view makes it easy to scan and delete videos that no longer matter. The review view also integrates with the watched/unwatched status, so you can filter to show only unwatched videos from the past two weeks, giving you a focused queue of content to work through. Think of the category view as your permanent, organized library and the review view as your inbox for recent activity.
Weekly Digest
YouTube Bookmark Pro
The digest view (above, first mockup) shows a time-boxed bucket with a countdown timer. The first video has been watched (green indicator and left border), while the other two are still pending. When the 2-day timer expires, those two unwatched videos will be pruned from the digest. They stay in your main library, but the digest clears to make room for next week's saves.
The privacy mode mockup (second) shows what your library looks like with Privacy Mode active. Every video title is replaced with bullet characters, every thumbnail is a solid gray block, and channel names are masked. The library structure is still visible - you can see your categories and the number of videos - but no content is exposed. Someone looking over your shoulder during a Zoom call would see a neatly organized panel with zero identifying information about what you watch on YouTube.
Group 6
Manage - Your data, your control
A video library is personal data. It reflects what you care about, what you are learning, and how you spend your time. YouTube Bookmark Pro gives you complete control over that data. You can export everything, import it elsewhere, switch between visual themes, and enjoy subtle design details that make the daily experience feel polished rather than utilitarian.
Export & Import (JSON)
Your entire library can be exported as a JSON file at any time. The export includes every video you have saved, along with its category, note, timestamp, watched status, save date, and all metadata. The JSON file is human-readable and well-structured, so if you are a developer, you can write scripts against it, parse it into a spreadsheet, or build your own visualization. The import function accepts the same JSON format, which means you can move your library between Chrome profiles, transfer it to a new computer, or restore it from a backup. The export is not a lock-in mechanism - it is the opposite. Your data belongs to you, and you can take it anywhere at any time. Some users export weekly as a personal backup. Others export when they switch machines. The point is that the option is always available and the format is standard. No proprietary binary files, no database dumps that require special tools to read. Just JSON that any text editor or programming language can work with.
Dark Mode & Light Mode
The extension supports both dark and light themes. By default, it follows your operating system preference - if your system is set to dark mode, the extension panel renders with a dark background and light text. If your system is in light mode, the panel uses a white background with dark text. You can override this behavior manually in the settings to force one theme or the other, regardless of your system setting. The dark theme is designed for YouTube's default dark mode, matching the color palette so the extension panel feels like a native part of the YouTube interface rather than a foreign widget bolted onto the side. The light theme is clean and minimal, using the same bone-white aesthetic as the rest of the extension's marketing pages. Both themes maintain full contrast ratios for accessibility, and all interactive elements (buttons, links, inputs) are clearly distinguishable in either mode. Switching between themes takes effect immediately without requiring a reload or restart.
Visual Polish
Small details define the difference between a tool you tolerate and a tool you enjoy. YouTube Bookmark Pro includes several optional visual touches that add personality without sacrificing usability. Hover glow effects give video cards a subtle blue shimmer when you mouse over them, providing clear feedback about which card you are interacting with. Scroll arrows appear at the top and bottom of a category shelf when it contains more videos than can fit on screen, guiding you toward content that is just out of view. These effects are toggleable in the settings - if you prefer a completely minimal, no-animation interface, you can turn everything off with a single toggle. The extension also supports the Creator Calm Skin, a muted color scheme designed for creators who spend long hours in the panel and prefer reduced visual stimulation. None of these details affect functionality; they exist to make the experience feel considered and intentional rather than generic. Regular YouTube viewers who interact with the panel dozens of times per day notice these touches, and they matter more than they appear to on a feature list.

YouTube's Watch Later feature was designed as a temporary holding pen, not a permanent library. It has no organizational structure, no search, no notes, and a hard cap of 5,000 videos. For casual viewers who save a handful of videos per week, it works well enough. But for anyone who uses YouTube as a learning tool, a research resource, or a content discovery platform, the limitations become obvious quickly. YouTube Bookmark Pro's library was designed from the ground up for people who save dozens or hundreds of videos and need to find, organize, and revisit them efficiently. Every feature in the comparison table above is available in the free tier - no subscription required.
Who is the library built for?
The library is not a niche tool for a specific profession. It is built for anyone who saves YouTube videos and wants to find them again. That said, certain workflows benefit more than others.
Students and self-learners
If you learn from YouTube - whether it is university lectures, coding tutorials, language lessons, or certification prep - the library becomes your study system. Save each video with a note summarizing the key concept, bookmark the timestamp where the instructor explains a tricky topic, and organize videos into categories that match your courses or subjects. When exam season arrives, search your library instead of searching YouTube again. Your notes surface the exact videos and moments you need, without rewatching hours of content to find the right 30 seconds.
Researchers and knowledge workers
Journalists, analysts, and academics who use YouTube as a primary or secondary source need a way to catalog and annotate video references. The library's notes and timestamps function like citation markers - you can record exactly where in a video a particular claim was made, who made it, and what context surrounds it. The export function produces structured JSON that can be processed into a bibliography or reference list. For research teams, the export/import cycle means you can share a curated library of relevant videos with a colleague by sending them a single file.
Content creators
YouTube creators constantly watch other creators for inspiration, competitive analysis, and trend research. The library gives you a structured way to save competitors' videos, annotate what worked and what did not, and organize reference material by content series or video format. A creator planning a video might create a project called "Research" and drag in 30 competitor videos, each annotated with notes about structure, hook techniques, and production quality. When it is time to write the script, the project contains all the references in one place.
Professionals and teams
HR trainers curating onboarding playlists. Marketers building a swipe file of video ad creative. Product managers collecting user research interviews published on YouTube. UX designers saving design system walkthroughs. In every case, the pattern is the same: save, organize, annotate, search, and revisit. The library fits into any professional workflow where YouTube is a source of knowledge or reference material.
What about Pro and Creator tiers?
Everything described on this page is part of the free Library tier. You do not need to pay anything to use any of these 20 features. But YouTube Bookmark Pro has two additional tiers for users who need more.
Pro - €6/month (from €4.90/month with annual billing)
The Pro tier adds subscription management on top of the library. You get subscription folders that organize your YouTube subscriptions into groups (similar to what PocketTube offers, but with auto-routing rules and channel health tracking). You also get cloud sync to keep your library and subscriptions consistent across multiple Chrome profiles or devices. Pro is for users who watch YouTube across multiple machines and want their data synchronized reliably.
Creator - €17/month (from €14.90/month with annual billing)
The Creator tier adds analytics tools for YouTube creators. You get your own channel's performance dashboard, competitor channel comparison, comment sentiment analysis, and audience overlap detection. Creator is built for people who produce YouTube content and need data-driven insights to grow their channels. It includes everything in Pro plus the full creator analytics suite.
Both paid tiers include the complete free Library. If you start with the free tier and later decide you need subscription management or creator analytics, upgrading does not affect your existing library - all your saved videos, notes, timestamps, and categories stay exactly where they are.
Getting started takes 30 seconds
YouTube Bookmark Pro is a Chrome extension. The installation process is identical to any other extension on the Chrome Web Store: click install, confirm the permissions, and the extension icon appears in your browser toolbar. No account creation required for the free tier.
Once installed, navigate to any YouTube video. The extension adds a side panel that you can open by clicking the extension icon or using the keyboard shortcut. The panel opens with the Library tab active and an empty library waiting for its first video. Click the save button on any video, choose a category (or create your first one), add an optional note, and your library has its first entry.
From there, the workflow is organic. Save videos as you watch them. Create categories as topics emerge. Add notes when you have context to capture. Use search when you need to find something. The library grows with your viewing habits, and the organizational structure evolves as your needs change. There is no setup wizard, no onboarding tutorial required, and no configuration needed before you start saving.
Start building your library
Free forever - no limits, no catch
Twenty features. Zero cost. Save every video that matters, organize it your way, search everything instantly, and never lose a bookmark again. The entire Library tier is free, permanently, with no caps on the number of videos you can save.
Frequently asked questions
Is the YouTube Bookmark Pro Library really free?
Yes. The Library tier is free forever with no limits. You can save unlimited videos, create unlimited categories, add notes and timestamps to every video, search across your entire library, use Privacy Mode, export and import your data, and use every feature described on this page without paying anything. There is no trial period, no freemium wall that locks features after 30 days, and no cap on the number of saves. The free Library is a permanent, fully functional tier - not a teaser for the paid plans. Pro (€6/month, or €4.90/month annually) adds subscription management and cloud sync. Creator (€17/month, or €14.90/month annually) adds analytics for YouTube creators. Both paid tiers are entirely optional and include the full Library.
How many videos can I save in the library?
There is no limit. The library stores videos locally in your browser's extension storage, which can handle thousands of entries without performance issues. Users with 2,000 or more saved videos report that search and navigation remain fast. The practical limit depends on your available browser storage, but for most users, this means tens of thousands of videos before you would ever approach a constraint. If you need to move your library to a new machine or free up space, the JSON export/import feature lets you back up and restore your entire library at any time.
Does the library sync across devices?
The free Library tier stores data locally in your browser. To sync your library across multiple Chrome profiles or computers, you need the Pro tier (€6/month, or €4.90/month annually), which includes encrypted cloud sync. With Pro sync enabled, your library, categories, notes, timestamps, and watched status stay consistent across every device where you have the extension installed. The sync is encrypted end-to-end, and your data is never sold or shared with third parties.
Can I use YouTube Bookmark Pro with Firefox or Safari?
Currently, YouTube Bookmark Pro is available exclusively as a Chrome extension. It works on any Chromium-based browser, including Google Chrome, Microsoft Edge, Brave, Opera, and Vivaldi. Firefox and Safari are not supported at this time. If you use a Chromium-based browser, the extension installs from the Chrome Web Store and works identically across all Chromium variants.
What happens to my library if I uninstall the extension?
If you uninstall YouTube Bookmark Pro without exporting your library first, the locally stored data is removed along with the extension. This is standard browser behavior for all Chrome extensions. To protect against data loss, we strongly recommend exporting your library as a JSON file periodically. The export includes every video, note, timestamp, category, and setting. If you reinstall the extension later, you can import the JSON file and restore your library exactly as it was. If you have Pro with cloud sync enabled, your data is also stored in the cloud and will restore automatically when you reinstall and log in.
Does YouTube Bookmark Pro collect or sell my data?
No. YouTube Bookmark Pro does not collect, store, or sell your personal data, browsing history, or viewing habits. The free Library tier stores all data locally in your browser's extension storage - it never leaves your machine. The Pro tier's cloud sync uses encrypted storage, and the encryption keys are tied to your account. Your library contents are never accessible to us, advertisers, or any third party. The extension requests only the minimum Chrome permissions necessary to function: access to YouTube pages (to capture video metadata) and storage (to save your library locally). You can review the full privacy policy for detailed information.
