Frequently asked questions

What granularity are the timestamps?

Per-segment (roughly per-sentence). Whisper natively produces segment-level timestamps aligned to the audio.

Can I click a timestamp to jump in the audio?

Yes. In Reader view, every timestamp is clickable and scrubs the audio player to that moment.

Is the tool free?

Yes. Up to 25 MB anonymously or 180 MB when signed in. No watermark and no per-minute fee.

What export formats are supported?

TXT (with inline timestamps), SRT, VTT, DOCX. Signed-in users also get PDF and JSON with structured timestamp data.

Do you identify speakers?

Not yet. Continuous timestamped text with no speaker labels. Diarisation is on the Pro roadmap.

Are recordings kept on your servers?

No. Audio streams to the transcription provider, gets processed once, and is dropped. Transcripts persist only on signed-in accounts.
