Questions people ask
- Can I get lecture notes instead?
- Yes — the video-to-text tool transcribes the recording locally.
- Is my lecture file uploaded anywhere?
- No. The conversion runs inside this browser tab with FFmpeg compiled to WebAssembly. The file is read from your device and never sent over the network, so private conversations stay private.
- Is there a size or daily limit?
- No server limit and no daily cap. The practical ceiling is your device memory; desktops handle multi-gigabyte files, phones are happiest with an hour or two at a time.
- Can I convert several files at once?
- Yes. Queue up to 60 files; each shows its own progress and you can download them one by one or as a single ZIP.
