About KnowStash

KnowStash turns YouTube videos into clean, searchable notes you keep, and watches channels, searches, and playlists so the useful new videos come to you already summarized. It is built and operated by KnowStash S.R.L., an independent software company registered in Romania.

What KnowStash is

A lot of the most useful knowledge published today is spoken in videos: market commentary, product reviews, tutorials, talks, interviews. Watching it all is impossible, and skimming misses things. KnowStash lets you capture any YouTube video once (we call it stashing) and then ask, in your own words or with a saved prompt, for exactly the note you want: a shopping shortlist from ten review videos, a weekly brief from the market channels you trust, a recipe card, a study guide, a growing wiki of everything a channel has taught.

Notes stream in clean, readable Markdown. They are versioned, searchable, organized into collections, and shareable with a link. Monitors watch a search, a channel, or a playlist for you, and can stash new videos automatically, write the note without being asked, or email you a digest or a written newsletter when something new lands.

KnowStash is a web app, and the browser extension is its YouTube companion. The web app at knowstash.ai holds your library and everything that runs on its own: search, collections, sharing, growing notes, queues, monitors, newsletters, saved prompts, billing, and settings. The companion adds what needs the video in front of you: ask about the one you're watching, read its notes beside the player, and build queues as you browse. One account, one library, one credit balance.

Who makes it

KnowStash is made by KnowStash S.R.L., a company registered in Romania, and is the company's sole product. We launched publicly in July 2026: the website and self-service signup opened first, and the browser extension shipped on the Chrome Web Store the same month. We are funded by the people who use the product. There are no ads, and your library is yours: notes exist for you, not for an advertising profile, and our privacy policy is written to be read.

How we think about pricing

Watching video with AI has a real cost, so we keep the pricing simple and visible. You buy credits up front, one credit for one hour of video, and spend them when you like. There is no subscription: nothing renews, and nothing is billed after the fact. Every action shows what it will cost before you run it, credits come with a published validity window, and every purchase carries a 30-day money-back guarantee. Current prices are always on the pricing page.
