Add KnowStash to your browser.
KnowStash lives right on YouTube: a calm panel beside the player and quiet badges across every thumbnail. Install the extension and you can stash a video and ask for exactly the note you want without ever leaving the page.
Free · works in Chrome, Brave, Edge & Arc · one click to install
Once it's added
- Pin it to your toolbar. Click the puzzle-piece icon in your browser and pin KnowStash, so it's always one click away.
- Create a free account at knowstash.ai/signup. Confirming your email drops your free starting credits into your balance. Already have one? Sign in.
- Open any YouTube video. The KnowStash panel appears beside the player: stash the video, ask for the note you want, and watch it stream in.
This is the official KnowStash extension, published by KnowStash S.R.L. It only
interacts with YouTube pages and your KnowStash account. See our
privacy policy. Updates install
automatically from the Chrome Web Store, and your notes and library live in your
KnowStash account, so updating the extension never touches your data.
Prefer the web?
The extension is where most people live. It's the quickest way to capture while you watch. But everything is also in the companion web app: browse and search your library, organize collections, set up monitors, and run the bigger jobs from a full screen. Same account, same library, same credits, no extension required.
