What you get from one lecture
Upload a recording or slides, up to 3 hours and 500 MB. Three lectures a day are free. This is what comes back.
Record right in the browser
Sitting in the lecture now? Press record. No app to install, nothing to transfer — it becomes your notes when you stop.
Chapters with timestamps
The lecture is split into named chapters, each with its start time. If the recording is on your device, click a time to play from there. For a YouTube lecture made with the extension, it opens that second on YouTube.
Edit anything
Fix a misheard term, delete a wrong key point, add a note of your own to a chapter. The exports use your version, and you can restore the original.
Daily review
Your flashcards come back on a schedule: rate each Again, Hard, Good or Easy, and the next review date moves. Cards that are due show on your Today page.
Key points extracted
The AI surfaces up to 20 of the ideas that actually matter — each with the exact timestamp it was said.
Vocabulary builder
Every technical term defined and tagged by difficulty. Export as Anki flashcards in one click.
A slide with every chapter
Each chapter shows the frame from your own recording at that moment, so the board or slide being discussed sits next to the notes about it. Video uploads and browser recordings — audio-only files have nothing to show.
Ask AI about the lecture
"Explain the third chapter simply." "What formula did they mention?" Full transcript context.
AI quiz generator
Multiple-choice questions written from your lecture. You pick 5 to 20, and each answer comes with an explanation.
Audio recap
Listen to your lecture notes as a 3, 5 or 10 minute spoken recap. Never uses up a lecture.
Full transcript
Searchable in the page, one click to copy, with a timestamp on every line. Download it as text (.txt), or as SRT or VTT subtitles. Our video transcript generator takes MP4, MOV, MKV and audio files directly.
100+ languages
The spoken language is detected automatically, so you do not have to choose it. 100+ languages are supported.
Export everywhere
PDF, Markdown, Obsidian, Notion or Google Docs, an Anki .apkg deck, and the transcript as .txt, .srt or .vtt.
