Turn any source into studyable knowledge
Drop in a lecture, a meeting, or a half-finished draft. LunaNotes hands back a structured note, then the diagrams, flashcards, and answers you need to actually retain it.
Three things it does properly
Where your material comes from, what the AI makes of it, and what you do with it after. Pick any row. Every surface beside it is the real interface, built in code.
Any source
A lecture, an episode, or a call. It transcribes the whole thing, no clipping, no ten-minute cap.

Ask anything about your notes
Three ways people use it
Studying for something
Lecture videos and reading turn into notes, concept maps, and flashcards, so revision starts from material you've already processed, not a blank page.
Start studyingRunning the work
Meetings, decisions, and project docs land in one library. Ask the Assistant what was agreed in March and get the note, not a search results page.
Start organizingBuilding a second brain
Books, articles, half-formed ideas. LunaNotes maps the relationships between them, so the connections surface instead of sitting in a folder.
Build your library
Your notes, reachable from any agent
LunaNotes ships an MCP server. Connect it once and the agent you already talk to can search your library, read a note, and write a new one back, with your work as its memory.
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. Bookmark whatever you're reading (filed in a collection, tagged, searchable) and it's in your LunaNotes library. On YouTube it sits beside the player for timestamped notes and one-click summaries.

Questions people actually ask
An AI note-taking app. Give it a source (a lecture, a meeting, an article, or your own draft) and it writes a structured note, then turns that note into diagrams, flashcards, and answers you can study from.
The AI reads whatever you give it and writes a structured note. From there you can generate a concept map or flowchart, build flashcards and quizzes, or ask the Assistant questions about anything in your library.
Yes. The free plan includes 100 AI credits a month, which is enough to try note generation, diagrams, and flashcards. Starter and Plus give you more monthly credits and storage, plus features like integrations, extra linked accounts, and priority support. Paid plans come with a 14-day free trial.
Yes, on paid plans. A Notetaker joins your Google Meet call, records and transcribes it, then turns the meeting into a summary with action items and a note in your library. Connect Google Calendar on Plus and it auto-joins the meetings you choose.
Your notes are encrypted and stored securely. We don't share your data with third parties, and your content is never reviewed by a human.
Yes. PDF, Markdown, or plain text, for backup or for moving your work somewhere else.
