Who this is for

Podcast mode

Podcast mode lifts the voice band, softens the bass grip and burns an episode progress bar or ring into the video.

Captions without a service

Load a .srt or paste text and tap-sync it, or run the built-in Whisper transcription on the clip — it downloads once and runs offline in your browser.

Square for feeds, vertical for Reels

Lock 1:1 or 9:16 and export a 30 or 60 second clip with normalised loudness.

How to do it

  1. Load the episode or clip
  2. Turn on Podcast mode (More → Podcast)
  3. Load or auto-transcribe captions
  4. Export 1:1 or 9:16
