Why Whisper?

OpenAI's Whisper is one of the most accurate open speech-recognition models available, trained on 99 languages, and known for handling accents and background noise better than most commercial alternatives.

🎯

High accuracy

Whisper's large-v2 model, the same one CaptionLab runs, is widely used as a benchmark for transcription accuracy.

🌍

99 languages

From Ukrainian to Vietnamese to Arabic — far beyond what Adobe's built-in captions cover.

🖥️

Runs locally

No OpenAI API account or per-minute billing — CaptionLab runs the model on your own Mac or Windows PC.

Frequently asked questions

Is CaptionLab affiliated with OpenAI?
No. CaptionLab is an independent plugin built by Edit Lab Tools that runs the open-source Whisper model — it's not an official OpenAI product and doesn't use OpenAI's paid API.
Which Whisper model does CaptionLab use?
CaptionLab uses Whisper large-v2, running via faster-whisper on Windows/Intel Mac and mlx-whisper on Apple Silicon, for the best balance of accuracy and speed on each platform.
Do I need a powerful computer to run Whisper locally?
CaptionLab runs on any Mac with macOS 11+ or Windows 10/11. It's faster with an Apple Silicon chip or an NVIDIA GPU on Windows, but works fine on CPU alone too — just slower.
