# Lecture to Notes

Drop in a recorded class and ToolSugar writes a summary, structured notes, a short quiz and a set of flashcards. Speech recognition and a small writing model both run in your browser, so nothing is uploaded. A small model can invent facts, so check the notes. Download everything as Markdown and CSV.

Runs on your device

## How it works

1. Add the recording of your class. Audio and video files both work, and only the sound is used.
2. Press the button and wait. Both models download on the first run, and a long lecture can take a while on a weak device.
3. Choose the spoken language, or leave it on automatic detection.
4. Make the notes, then open the Summary, Notes, Quiz and Flashcards tabs and download what you want to keep.

## Key facts

- **You get**: Summary, Markdown notes, a quiz with answers, flashcards and the transcript
- **Downloads**: Markdown notes, flashcards as CSV, transcript as plain text
- **Length limit**: A 60,000 character transcript, about 75 minutes of talk
- **What leaves your device**: Nothing. Speech and writing both run in the browser
- **First run**: A speech model of about 77 MB (206 MB with WebGPU) and a writing model of about 786 MB, each downloaded once
- **Free runs**: Each run counts as one of 5 free AI runs in any rolling 24 hours, with no sign up

## Common uses

- Review a one hour seminar in ten minutes before the next session.
- Test yourself on a recorded revision class using the quiz, and see the right answer straight after each pick.
- Import the flashcard CSV into your favourite spaced repetition app the night before an exam.

## Questions

### Is my recording uploaded?

No. The recording is transcribed in your browser and a small writing model on your device turns the transcript into notes. Neither the audio, the video nor the text is sent anywhere. The first run downloads about 77 MB for speech and 786 MB for writing, and both are cached.

### What happens with a very long class?

A transcript over 60,000 characters, about 75 minutes of talk, is too long for one set of notes. The tool still gives you the full transcript and tells you to cut the recording into parts with the Audio Cutter, so a long wait is never wasted.

### What if I hit the daily free limit?

Each run counts as one of 5 free AI runs in any rolling 24 hours, shared with the other AI tools. When they are used the tool says when your next run opens. A run that fails is refunded, and no account is needed.

### Can I trust every quiz answer?

Treat them as a study aid. The notes come from a small writing model reading an automatic transcript, so a misheard word or an invented fact can slip through, and quiz answers can be wrong. Check anything important against your course material.
