Frequently asked questions
Does it work on recorded lectures that aren't on YouTube?
Yes. Upload lecture recordings (video or audio, up to 1 GB), record in the browser, or paste a Google Drive link. AI transcription handles videos without captions.
Can I use it for lectures in other languages?
Yes — transcription and summaries work in 37 languages, and you can generate the summary in a different language than the lecture.
Is there a free plan for students?
Yes. The free plan includes about 450 minutes of public video processing plus a private upload — enough to try it on a real course before upgrading.
Can I export my notes?
Export summaries, transcripts, highlights and notes to Notion or Readwise, download as PDF or DOCX, or copy as Markdown.
