VidVaultA private library for the videos you learn fromLaunching this month

Keep the videos you learn from. Find the moment you needed.

VidVault turns scattered bookmarks and watch-later lists into a private library. Save a video in one click while you watch, write notes pinned to the exact second, and come back to them from your browser or your phone. Saves are written on your device first, so a bad connection never loses your work.

01 — Problems it solves

Watch-later lists turn into graveyards

Bookmarks and platform playlists pile up with no context. VidVault saves each video with its title, channel and your own tags, so the library stays searchable instead of endless.

The useful moment is buried in a long video

A note pinned to 14:32 takes you back to 14:32. No more scrubbing through an hour-long lecture for the one explanation you needed.

Learning is split across devices and apps

Save on the laptop, share from the phone, open the same library on the web. Once you sign in, everything lands in one place.

A weak connection loses your work

Saves and notes are stored on your device first and synced when the connection allows, so nothing you typed on a bad network disappears.

02 — What it does

Save while you watch

The extension adds a save panel to YouTube and supported Facebook video pages in Chrome and Firefox. Title, channel and link are captured for you. VidVault keeps references and your notes, never the video file.

Notes on the timeline

Write a note at the current playback time, or type a timestamp yourself. Edit notes later and export them as Markdown.

Organise it your way

Tags, categories, ratings and playlists, with quick filters for clips, favourites and videos with notes. Saved views remember a search and its filters.

A web workspace for studying

Open a saved video to watch it, add notes and resume where you stopped. Import a transcript you already have and search inside it, jumping straight to the matching moment.

Android, share-first

Share a link to VidVault from YouTube, TikTok, Instagram, Facebook or X. The app fills in the title and thumbnail where the platform allows, and your library, playlists and notes are on the phone too.

Watch time that means something

Optional watch history counts real time spent watching, not how far you dragged the slider, with completion and channel breakdowns. It stays off until you turn it on.

03 — Install the Chrome extension

Until VidVault is in the Chrome Web Store, you add it to Chrome yourself. It takes a minute.

Download for ChromeVersion 0.2.4 · ZIP, 270 KB · Chrome 116 or newer
  1. 1Download the ZIP and unzip it. Keep the vidvault-extension folder somewhere it will stay: Chrome runs the extension from it.
  2. 2Open chrome://extensions and turn on Developer mode at the top of the page.
  3. 3Choose Load unpacked and select the vidvault-extension folder.
  4. 4Pin VidVault from the puzzle-piece menu, then open a YouTube video and press save.

Installed this way, VidVault does not update itself: download the new version from this page when we release one. Chrome may remind you that developer-mode extensions are on. Firefox needs Mozilla's signature first, and arrives with the store listings. SHA-256 checksum

04 — How it works
  1. 1Add the extensionDownload it from this page and add it to Chrome. It works on its own before you sign in. Firefox follows once Mozilla has signed it.
  2. 2Save and take notesPress save on a video, add tags, and write notes at the second they belong to.
  3. 3Sign in to syncCreate an account to see your library on the web and on Android. Saves made before you signed in join your account only when you choose.
  4. 4Come back and studySearch your library, resume a video, open a note's moment, and build playlists for a course or a topic.

  • An iOS app

05 — Work ahead

01Getting into the storesThe Chrome Web Store and Firefox Add-ons submissions are prepared but not yet approved. Until they are, Chrome users install the extension from this page, without automatic updates, and Firefox users wait for Mozilla's signature.
02Capture beyond YouTube and FacebookOther video sites change their pages often, which breaks reliable capture. For now they come in through link import and sharing; on-page capture is added only where it holds up.
03Watch time on phonesPhones don't run browser extensions, so automatic watch time works only on desktop today. Measuring it from VidVault's in-app player is next.
04Study help you can checkAn optional assistant can summarise a transcript you import and answer questions with links to the source moments. It runs only where the server enables it and you confirm each request, and its answers can be wrong, so it stays optional.

Questions

Does VidVault download videos?

No. It saves a reference to the video (title, channel, link and thumbnail) along with your own notes, tags and progress. Videos play from the site they came from.

Do I need an account?

Not to start. The extension saves on your device without one. An account adds sync across the web and Android, and saves you made before signing in move into it only when you choose.

Which browsers and phones are supported?

Chrome and Firefox on desktop, and Android phones. Firefox for Android and iPhone are not supported at launch.

When can I install it?

The Chrome extension, now: download it from this page. The store listings, Firefox and the Android app follow with the launch planned for November 2026. Leave your email and we'll tell you when they are live.
