How your recording becomes a book.
Your lecture's audio and readable slides provide the source material.
The explanation from class
We transcribe the audio so the book follows what your lecturer explains.
Figures from the slides
We read the video frames for relevant diagrams and slide text. Those figures sit beside the explanations they belong to.
Chapters you can navigate
The transcript becomes chapters and sections that follow the lecture, with definitions for key terms.
Text you can work through
Each section becomes readable prose. You can check the explanation against the lecture and edit the draft where needed.
A copy you can keep
Download a PDF or ePub with captioned figures beside the text. You can edit the chapters online and export the book again.

- There are brief interruptions.
- You plan to edit and refine output.
Check the parts that matter
- Check the draft against your lecture and course materials before you rely on it.
- Inaudible speech, unreadable slides, missing board work, or incomplete derivations may leave gaps. The book cannot recover material the recording does not contain.
