There's a library's worth of knowledge locked inside YouTube. KnowStash turns it into clean, searchable notes you keep.

There's a library's worth of knowledge locked inside YouTube. KnowStash turns the videos you care about into clean, searchable notes, written by AI while you get on with your day. Capture on YouTube, keep it at knowstash.ai, and let monitors watch the channels you can't. ON YOUTUBE: THE EXTENSION • Ask anything about the video you're watching, in your own words, and get an answer grounded in the video itself. Narrow it to the chapters you care about. • Not sure what to ask? Suggest writes a first prompt you can edit. • Every answer becomes a note you read beside the player. Timestamps in the note jump the video to that moment. Copy it, download it as Markdown, or share it with a link, right there. • Line up a queue as you browse. One click on any thumbnail adds a video, and a KnowStash button in YouTube's top bar shows which queue it lands in. • Send the whole queue at once and choose what comes out: a note per video, one note drawn from all of them, or one note the queue keeps adding to. Or send it empty to save them all for later. Queues run side by side and carry on without you. • The price and the wait show before you press send. While it runs, a countdown says how long is left, and the queue picker marks every queue that is working. • Move on while it works. Go to another video and the note you asked for is still written, ready when you come back. • Quiet badges on thumbnails show what is already yours. AT KNOWSTASH.AI: EVERYTHING ELSE • Your library: every note and every video you have kept, searchable and filtered by channel, date or collection. • Notes that grow. Feed a note new videos and it updates in place, with every version kept. • Collections to organize, a public link to share a note, and Markdown export for Obsidian, Notion or wherever you write. • Monitors that watch a channel, a playlist or a search, running as often as every 15 minutes, and save and note whatever is new. You set how much a run may spend, filter by upload date or words in the title, and preview what the next run would pick up. • A newsletter written from those notes and sent by email, instantly, daily or weekly, with sections and links back to the videos. Every issue is kept in your archive. • Leave the page while a note is written: a small card keeps track of what is running. • Saved prompts, so the questions you ask often are one click away. • The whole app on a phone. It is a website, so there is nothing to install and nothing to keep in step. Same account, same library, same credits. The panel links you to the site whenever you need more than the video in front of you. HOW IT WORKS 1. Open any YouTube video. The KnowStash panel appears beside it. 2. Ask for the note you want, or press Suggest for a first prompt. The video is saved the first time you ask, and saving it never costs again. 3. Find it later at knowstash.ai: searchable, versioned, and yours to keep. PRICING The extension is free to install. A new account starts with 3 free credits, no card needed. One credit is one hour of video. After that you buy credits at knowstash.ai in packs of 10, 20 or 50, pay as you go, no subscription; a pack is valid 3 months. Teams buy 100 to 500 credits a year on one invoice. Prices are shown before VAT or sales tax. Payments are handled by Paddle, with a 30-day money-back guarantee on unspent credits. PRIVACY KnowStash needs a free account (Google sign-in or email/password). Notes are only made from videos you choose. No browsing-history collection, no ads, no selling data. Two switches in the toolbar popup decide where KnowStash appears: video pages, browsing pages, or neither.
