■ 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.
‣ Why must I keep the iOS app open while it transcribes?
iOS apps are fundamentally restricted from operating in the background for extended periods.
‣ 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.

Firstly I would like to thank the developers for this app. I am hard of hearing and therefore, for transcribing the lectures I was looking for something like this. My only complaint or rather request is that if possible, can you make it so that there is real-time transcriptions? Also if possible add a feature to automatically save the transcribe, because more than once I accidentally closed the app or my screen and lost the transcription, and since there is no feature to save the recording, I was unable to review the lecture.Anyways, I would like to express my gratitude for such an app, and even that totally free!!!!
Love it!

This App deserves more ratings and reviews. It Just Works™ and does a great job.The Medium model on the M1 iPad Pro is extremely performant.However the Complete model on my old Intel MacBook Pro is slow and a respurce hog. It would be great if pone could choose the model size. Medium is perfectly adequate for my application.
Better than paid alternatives

Tried couple of other paid services but the transcription quality for this was far better.
Best Free App possible

This app is the best app you can get for speech-to-text. I can't believe it. The text is almost the same as the speech. And the great thing about this app is, It's not asking the god damm money. I appreciate the developer.
