An AI notes app for learning. Makes structured, timestamped notes from YouTube videos, PDFs and documents, then turns them into flashcards, diagrams and answers you can chat with. A Chrome extension puts a notes panel beside the YouTube player.

Otter.ai

An AI meeting assistant. Its bot joins Zoom, Google Meet and Microsoft Teams calls, transcribes them live and writes summaries and action items. Also transcribes recordings and uploaded audio or video files.

Introduction

If your notes start in a meeting, Otter.ai is the more focused tool: its bot joins the call, transcribes as people talk, and writes the summary and action items afterwards. LunaNotes does not join meetings. If your notes start in a lecture, a course or a long explainer on YouTube, the job is different. You don't need a live transcript; the video already has one. You need the hour turned into notes you can study, and a way to test yourself on them. That is what LunaNotes is for. Paste a YouTube link (or open the video with the Chrome extension) and LunaNotes writes a structured note with headings and timestamps that jump back to the moment each point came from. Add the lecture slides as a PDF and both become one note. From there, make a flashcard deck with spaced-repetition review, a diagram of the concepts, or ask questions and get answers with numbered sources.

Frequently asked questions

Can LunaNotes record my meetings like Otter.ai?

No. LunaNotes does not send a bot to Zoom, Meet or Teams. It is built for learning from videos and documents. If you need live meeting transcription, Otter.ai is the better fit.

Can Otter.ai make notes from a YouTube lecture?

Otter transcribes meetings, recordings and uploaded files. Its pricing page does not list YouTube links as a source, so you would need to download the audio first. LunaNotes takes the YouTube link directly and uses the video's captions.

Does LunaNotes make flashcards from a lecture?

Yes. Any note, including one made from a video or PDF, can become a flashcard deck. Cards come back on a spaced-repetition schedule, and you can quiz yourself or export the deck to Anki.

Is LunaNotes affiliated with Otter.ai?

No. Otter.ai is a trademark of its owner. This comparison is written by LunaNotes from Otter's public website as of October 2026.

Conclusion

Otter.ai and LunaNotes overlap less than their categories suggest. Otter captures conversations as they happen; LunaNotes turns material you already have, like a recorded lecture, a course video or a chapter PDF, into notes you can study and test yourself on. If you are taking an online course or learning from long YouTube lectures, start with LunaNotes' Free plan and the Chrome extension, and see whether the notes and flashcards save you the rewatch.
