Your lectures, as text.
ClassToText is a Chrome extension that turns recorded lectures and other audio or video into accurate, timestamped transcripts, emailed to you or saved straight to your Downloads.
Your first 10 hours are free. No card needed.
How it works
1Open a recording
Play a recorded lecture or webinar in Chrome, on a platform such as Webex or your university's video portal.
2Click Transcribe
One click in the extension. You can rename the file first; the title is used for the transcript.
3Get your transcript
A few minutes later it arrives by email, with subtitles (.srt) attached, or lands in your Downloads folder. Or both.
Built for studying
Timestamped paragraphs
Jump straight to the moment in the recording you want to review.
Fully automated
AI speech recognition does the work: no one listens to your recordings.
Private by design
Processed in the EU. Recordings and transcripts are deleted once you have your copy.
Pricing
Free
10 hours of transcription in total, to try it on your own courses.
