An AI notes app for learning. Makes structured, timestamped notes from YouTube videos, PDFs and documents, then turns them into flashcards with spaced-repetition review, diagrams, and answers with numbered sources. A Chrome extension adds a notes panel beside the YouTube player and saves pages to your library.

Readwise

Two products sold together or apart. Readwise syncs highlights from Kindle, Apple Books, Reader and other apps and resurfaces them in a Daily Review, with exports to Notion and Obsidian. Reader is a read-it-later app for articles, PDFs, EPUBs, RSS, newsletters and YouTube transcripts, with the Ghostreader AI assistant.

Introduction

Readwise is one of the best tools for people who read a lot. You highlight as you read, in Kindle or in Reader, and Readwise brings those highlights back in a Daily Review so they stick. Reader handles articles, PDFs, EPUBs, newsletters and even YouTube, where you can highlight the transcript. LunaNotes is for a different kind of input: material you have to learn, not just read. A two-hour lecture or a course module is too long to highlight line by line. LunaNotes writes the note for you, with headings, key points and timestamps that jump back to the moment in the video. Add the slides as a PDF and both become one note. From the note, LunaNotes makes what you need to study: a flashcard deck with spaced-repetition review and quizzes, a diagram of the concepts, or answers to your questions with numbered sources. The Chrome extension puts all of that in a panel beside the YouTube player.

Frequently asked questions

Does Readwise work with YouTube?

Yes. Readwise Reader shows a YouTube video with its transcript so you can highlight it. LunaNotes takes a different approach: it writes a structured note from the video, with timestamps, and can turn it into flashcards and diagrams.

Can LunaNotes import my Kindle highlights?

No. LunaNotes does not sync Kindle highlights. If book highlights are your main source, Readwise is the better tool for that part.

Does LunaNotes have spaced repetition?

Yes. Flashcard decks come back on a review schedule, with at most 8 new cards a day so the queue stays short. You can also quiz yourself on a whole deck or export it to Anki.

Is LunaNotes affiliated with Readwise?

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

Conclusion
