How to take notes from YouTube videos
The useful part of a forty-minute video is usually five minutes of substance, and the note-taking part of watching it is usually the reason it never happens. This guide shows the manual options, why they disappoint, and how to make notes from YouTube videos automatically with KnowStash: capture once, ask for exactly the note you want, and let future videos arrive already summarized.
The manual ways, and where they fall short
Pausing to type works, but it turns one hour of video into ninety minutes of work, and the notes are only as good as your patience in minute fifty. Copying the transcript gives you every "um" and sponsor read with none of the structure. And pasting a transcript into a chatbot gets you a generic summary of what the video was about, when what you usually need is specific: the exact settings recommended, the reasoning behind a pick, the steps in order, the numbers quoted. A good note answers your question about the video, not the average question.
Step 1 · Capture the video once
With KnowStash you stash a video: one click in the browser extension panel next to the player, or paste the link into the web app. Stashing fetches and indexes what was actually said so it can be asked about later. You do it once per video; the video stays in your library and every future note draws on it without fetching again. The meter is simple: 1 credit is 1 hour of video, the price shows before you run anything, and new accounts start with free credits, so the first videos cost nothing to try.
Step 2 · Ask for the note you actually want
This is where automatic notes stop being generic. You ask in your own words, or with a prompt you save once and reuse. Some asks that work well:
- "List every product mentioned with what the reviewer liked and disliked about each."
- "Turn this into a recipe card: ingredients with quantities, then numbered steps."
- "Make a study guide: key concepts with definitions and one example each."
- "What is the argument here, what evidence is offered, and what is glossed over?"
- "Action items only: what does the presenter say to actually do?"
The note streams in as clean, readable Markdown. If it is close but not right, ask again or refine it; the video is already captured, so iterating on the note is the cheap part.
Step 3 · Keep notes somewhere they stay useful
Notes land in a library that is searchable and organized into collections, so "that video about pension funds from a few months back" is a search, not an archaeology dig. Notes are versioned when you update them, and any note can be shared with a link. The library follows you: the extension and the web app are two doors to the same account.
Taking notes from many videos at once
The real time savings show up above one video. Select several stashed videos and ask for a single note across all of them: ten reviews become one decision-ready shortlist, a course playlist becomes one structured study guide. Point KnowStash at a playlist and it can stash the lot. For the patterns people build with this, see the use cases page.
Notes that write themselves
For channels and topics you follow, skip the manual step entirely. A monitor watches a channel, a search, or a playlist, stashes what is new on your schedule, and can write the note without being asked, fold each new video into one growing reference note, or email you a written roundup. Set it up once and "keeping up with the channel" becomes reading notes that arrived on their own.
What it costs
1 credit is 1 hour of video, stashed and noted, with the price visible before anything runs. Free credits on signup cover your first videos; after that, every subscription tier costs the same per credit, and a bigger plan is simply a bigger monthly allowance. Details and current amounts are on the pricing page.
Try it on the next video you watch
Add KnowStash to Chrome (works in Chrome, Brave, Edge, and Arc) or create an account and use the web app in any browser. Stash the next video you would normally add to watch-later, ask for the note you wish existed, and see whether you ever take video notes by hand again. The help center covers everything this guide skimmed.
