What file type does this podcast to captions tool support?

This free version is intentionally simple and supports MP3 uploads only.

Does this tool upload my audio?

Yes. Your MP3 is sent to the transcription service so the caption timing can be generated, then you can download the SRT file.

How accurate are the captions?

It is a useful first draft, not a final review pass. Always check the SRT before publishing podcast clips, episodes, or transcripts.

Who is this tool for?

It is built for podcasters, interview editors, clip teams, and anyone who wants a fast MP3 to SRT workflow without extra setup.
