## Changelog

User-facing changes. Dates are UTC.

#### 2026-10-04

- AI agents: common field names (`url`, `urls`, `startUrls`, `query`, `keywords`...) are accepted, and an empty input runs a small sample from the input form instead of failing.

#### 2026-10-03

- New: **`aiFallback`** transcribes videos that have no captions with AI (open-source Whisper, 99 languages), billed $0.010 per started minute of audio instead of the transcript price. Off by default; runs with it on use 2 GB of memory. `maxAiMinutesPerVideo` caps the length. New fields `transcriptSource` and `aiMinutesBilled`.

#### 2026-10-02

- Whole channels and playlists as input (`channels`: `@handle`, channel or playlist links), newest videos first, up to 2,000 per channel. Listing is free; only transcripts are charged.
- `onlyNewVideos`: on a schedule, each run returns only the videos uploaded since the last one.

#### 2026-09-26

- Fixed: rare runs failed with "Schema validation failed" when a result had empty fields.
- First public version.
