02 / 07 — SCREENSHOT

The workshop, on your machine.

UtterPad — dark mode UtterPad — light mode
03 / 07 — PILLARS

Three certainties.

P · 01

On-device by default.

Audio leaves your file only if you point UtterPad at a cloud model. The default engines run entirely on your Mac. No network, no telemetry.

P · 02

Pro-tool surface.

Batch queue with per-row model, language, output-format and folder overrides. Drag-reorderable, drag-resizable columns. Phased progress bars that reset between extract and transcribe.

P · 03

Every transcript, every format.

Each completed job auto-exports .srt, .vtt, .txt, .ass and .json — beside the source or to a folder you pick per file.
