For researchers writing papers, reviews or talks from recorded lectures, conference talks and articles. Save them, ask across them, and check each claim against the passage it came from before you cite it.
Last reviewed: October 2026
MensorAI started as a YouTube note-taking tool for learners. Now it saves articles, passages and YouTube moments as you go, and when you sit down to write, you ask across all of them. Every answer links back to the passage it came from.
Sound familiar? Here’s what usually gets in the way.
Here’s what it does for this kind of work today.
Save a talk at the moment you’re at, with the captions around it when the video has them, and add your own note. The note stays separate from the source text, so you can tell what you thought from what was said.
Ask a question across your whole library, or type @ to compare a few sources. The answer shows which sources it used.
Every claim links to the passage behind it, and for a video to the moment when the captions have timestamps. Quotes are checked against the source text.
Keep the claims you’ll cite in a piece, grouped by the questions your paper asks. Each one keeps its source passage. Copy it into your editor with citations and links.
It helps you write from what you read and watch. Save articles, YouTube moments and your own notes, then ask a question across all of it. Every claim in the answer links to the passage it came from, and you can keep the claims you’ll use in a piece and copy it into your editor.
Saving is free. Asking across your library and finding videos on YouTube need an active trial or a paid plan, and there’s a 7-day free trial of Pro features with a limited AI allowance. No credit card required. After that, plans are $9, $19 or $22 a month, and they differ only in AI requests per day.
The browser extension works in Chrome, Edge, Brave and Arc on desktop, and it opens as a popup. The web app runs in your browser and takes YouTube links. There’s no mobile app.
Answers depend on the captions and text a source has. You can save a video without captions, but MensorAI will only have your own note to work with for it.
