How it works
From video to note in three moves.
Stash it
One click on any YouTube video. KnowStash fetches and indexes it. That's your raw material, kept forever. Stash once; using it never costs again.
Ask for the note you want
In your own words, or with a saved prompt. A recipe card, a study guide, a wiki of your favourite artist. Whatever's in the video, ask and it streams out.
Keep it forever
Notes land in your library: searchable, versioned, organized into collections, shareable with a link.
What you get
Everything between watching and knowing.
It lives right on YouTube
The Chrome extension adds a calm panel beside any video and quiet badges on every thumbnail. Stash from the watch page, queue from the home feed. no copied links, no second tab.
- Sidebar panel on every watch page
- stash / notes badges across YouTube
- One-click add-to-queue on thumbnails
Notes in your words, not a generic summary
Ask for exactly the note you want: the recipe without the life story, a wiki of your favourite band, the week's market calls, what the Q&A actually answered. Pick how much horsepower each note deserves; the price shows before you send.
- Streams live, in clean formatted markdown
- Standard or premium presets per note
- Scope it to a chapter, or span several videos
A library that compounds
Every video you've stashed and every note you've written, in one searchable place. Collections keep topics tidy. Sharing a note is one link, and it always shows the latest version.
- Search across all your notes and videos
- Collections, channels, and date filters
- Public share links, revocable anytime
Put YouTube on autopilot
Point a monitor at a search, a channel, or a playlist. New uploads get found, stashed, and noted while you sleep, folded into one growing brief or a note per video, with an email when something lands.
- Checks as often as every hour
- Auto-stash and auto-note every new find
- One growing brief, or a note per video
- Email you when there's something new
Notes that grow, and leave with you
A note isn't frozen once it's written. Feed it new videos and it grows: same document, versioned. Merge several notes into one brief. And everything exports as clean Markdown, ready for your notes app or the next AI tool in your chain.
- Update a note with new videos: one document, versioned
- Merge many notes into a single brief
- Download any note as Markdown (
.md) - Drops straight into Obsidian, Notion, or your favourite AI tool
