Otter.ai

Otter.ai records or imports audio and produces a transcript with speakers labeled, plus a written summary and action items. It is best known as a meeting note taker, but podcasters use it for pre-interviews, research calls and rough transcripts of recorded episodes.

You can upload an audio file, search the transcript and highlight passages, which helps when you need a quote or want to find the strongest part of an interview. It has mobile apps for recording in person.

Automatic transcripts get names, jargon and crosstalk wrong, so correct anything you plan to publish. If you record calls with guests, tell them a transcription tool is running. Exports to text and subtitle files make it easy to move a corrected transcript into your episode page.
