An AI note-taking app. Give it a source, like a lecture, a meeting, an article, or your own draft. It writes a clear note, then turns that note into diagrams, flashcards, and answers you can study from.

How do the AI features work?

The AI reads what you give it and writes a clear note. From there you can make a concept map or flowchart, build flashcards and quizzes, or ask the Assistant about anything in your library.

Is LunaNotes free to use?

Yes. The free plan gives you 2,000 AI credits a month. That's enough to try notes, diagrams, and flashcards. Starter and Plus give you more credits and storage each month, plus integrations, more linked accounts, and priority support. Paid plans come with a 14-day free trial.

Can LunaNotes take notes in my meetings?

Yes, on paid plans. A Notetaker joins your Google Meet call, records it, and transcribes it. Then it turns the call into a summary with action items, plus a note in your library. On Plus, connect Google Calendar and it joins the meetings you pick on its own.

How secure is my data?

Your notes are encrypted and stored safely. We don't share your data with third parties, and no person ever reviews your content.

Can I export my notes?

Yes. PDF, Markdown, or plain text, for backup or for moving your work somewhere else.

Three things it does properly

Where your work comes from, what the AI makes of it, and what you do next. Pick any row. What you see beside it is the real app, built in code.

Any source

A lecture, a show, or a call. It transcribes every word. No clips, no ten-minute cap.

AI generation

One note, and three things it turns into, all from the same source.

Your library

All you've saved, in one place that can answer questions about it.

Three ways people use it

Studying for something

Lectures and reading turn into notes, concept maps, and flashcards. Review starts from work you've already done, not a blank page.
Start studying
Running the work

Meetings, decisions, and project docs land in one place. Ask the Assistant what you agreed on in March and get the note, not a list of search results.
Start organizing
Building a second brain

Books, articles, half-formed ideas. LunaNotes maps how they link, so the connections show up instead of sitting in a folder.
Build your library

Your notes, reachable from any agent

LunaNotes has an MCP server. Connect it once. Then the agent you already use can search your library, read a note, and write a new one back.

Set up the MCP

Notes you write together

Share a note, edit it at the same time, and watch everyone's cursor move as they work.

Save any page. Take notes on YouTube.

A free browser extension. Save what you're reading and it lands in your library, filed, tagged, and easy to search. On YouTube it sits next to the player for timestamped notes and one-click summaries.
