The challenge

A single podcast episode or keynote holds a week of short-form content. Getting it out by hand takes hours: transcribing, hunting for the strong moments, cutting, captioning, scheduling.

Most of that work is mechanical. It should not need a person.

What we built

A platform that does the mechanical work between recording and publishing.

  • Transcription

    Every upload transcribed automatically, ready to search and quote.

  • Clip generation

    The strongest segments identified and cut for vertical and widescreen, with captions per platform.

  • Newsletters

    Email drafts written from the same transcript, ready to edit and send.

  • Publishing

    Scheduling and a calendar, so the whole week runs from one screen.

The outcome

Live at therapidcaster.com as a multi-tenant product with credit-based accounts.

Like everything in the ledger, we operate it ourselves. The pipeline runs daily, and improvements ship to real users.
