- AI Ad Detection — Transcribes episodes with Groq Whisper and uses an LLM to identify ad segments before playback

CleanCast uses a two-stage detection pipeline:
- Stage 1 (Coarse) — The episode audio is transcribed via Groq Whisper. The transcript is split into time-chunked blocks and each block is analyzed by an LLM to flag likely ad segments.
- Stage 2 (Refine) — Flagged segments are refined to find precise start/end timestamps before playback reaches them.
Ad detection runs in the background while you listen, with no interruption to playback.
