■ FAQ

‣ Can I edit the text in the app?

I don't plan to support any editing. Export the transcription and edit it in a proper text editor.

‣ Why is the app so large?

The app delivers the highest quality transcription on the market for 100 different languages. Rather than asking why it's so large, the real question is how is it so small.

‣ Why is the transcription so slow?

The app favors accuracy over speed. However, performance is expected to improve in the coming months.

‣ Can I delete some of the languages to save space?

This is unfortunately not possible. The model has all the languages stored together in a way that makes it impossible to remove just some languages.

■ Technical details

■ Privacy

The transcription is done locally on your device. Nothing leaves your device. The app is not even able to connect to the internet due to self-imposed restrictions that are enforced by macOS (no network entitlement).
