Source Cards

Every video becomes a searchable card with transcript, notes, timestamps, and extracted ideas.

Quote Clips

Save the line and the moment it came from, so the source stays attached to the idea.

Angle Cards

Turn a useful source into a take, hook, framing, or question you can actually use.

Draft Packs

Bundle hooks, claims, quotes, examples, and an outline for the next thing you make.

From watched to written

Your research becomes material in four moves.

01

Capture a source

Drop in a video or use the browser extension. The source lands with transcript, metadata, and context intact.

02

Extract the signal

Pull the quote, claim, or angle while the source is still attached to the moment it came from.

03

Research with the agent

Ask your saved research to connect sources around the piece you are trying to make next.

04

Find it when you write

Build from saved hooks, claims, quotes, examples, and outlines instead of researching twice.

Browser Extension

Capture the useful part without leaving the video.

The MensorAI sidebar sits on top of YouTube. Pull quotes, annotate angles, ask about the source, and keep the material close to the piece you are making next.

Not another place to dump links

Watch Later, notes apps, and AI chats all lose a different part of the source-to-piece path.

Frequently Asked Questions

What happens to my library if I cancel my plan?

Every source, note, and quote stays with you forever. You just lose access to AI features like Draft Packs, Source Chat, and semantic search. You can still view, edit, and export everything you've captured.

Does it work with sources beyond YouTube?

Today MensorAI is YouTube-first because that is where many creators already spend their time. The direction is broader: more creator inputs, more media formats, and better ways to reuse what you collect.

Is my library private?

Yes. Your workspace is private by default. Only breakdowns you explicitly choose to publish become visible to the community. We never share or sell your data.

What's the difference between Starter, Plus, and Pro?

Starter gives you the core workspace plus basic AI features (Draft Packs 5/mo, Source Chat 3 msg/session). Plus adds Quote Clips, Angle Cards, Socratic prompts, and knowledge graph syncing with higher limits. Pro removes all limits, for just $3/mo more than Plus.

What happens after the free trial?

After your 7-day trial with full Pro access, you'll need to choose a plan to continue. All your sources and notes stay intact, so you just pick the tier that fits how much you create.

Early Access

A note from the builder

Most of making something is research. For me that meant hours of YouTube and articles for a single video or essay, with notes scattered across whatever app I had open. Then I'd sit down to make the next thing and none of it was there. I'd re-watch the same videos and hunt for the same quotes I'd already found once.

So I built MensorAI for myself first. Everything I learn from now lands in one place, and I can ask it questions later instead of digging through old notes hoping I wrote the good part down.

If you make things for a living and you're tired of the good stuff vanishing the moment you close the tab, I think you'll get it.
