FAQ
How can a student turn a lecture into text?
Record or upload the lecture audio, choose the language or auto-detection, then generate a transcript for review and study.
Can lecture text be translated?
Yes. After transcription, the lecture text can be translated into another language for multilingual study.
Is lecture transcription useful for exam preparation?
Yes. Searchable lecture text helps students find terms, create summaries and return to explanations faster than replaying the full recording.
What are the demo limits versus a signed-in upload?
The free demo is limited to a short clip (about 60 seconds, 25 MB) with a small hourly request cap per IP. With an account you can upload large audio or video files (up to about 2 GB per file) and the amount you can process depends on your subscription—check Pricing.
