Both transcription and AI features run 100% locally, so your data never has to leave your device FAQ: What is the longest transcription supported? We support regular transcription of voice notes, audio files, and video files up to 8 hours long. We support live transcription up to 2 hours long. You can transcribe as many recordings as you would like. Is the app actually fully local? Yes! The app uses local transcription and LLM models, so all transcription and AI features work on-device. A network connection is only required once to download each transcription or AI model. Your data never leaves your device unless you choose to share it. We provide optional iCloud sync to back up your data and sync data between devices. If you have this disabled, your transcriptions will be deleted if you delete the application. We recommend backing up important transcriptions. Why do I have to keep the app open while it is transcribing? The app has to be open during transcription as iOS limits apps from operating in the background for extended amounts of time. If you are unable to run the app at the moment, you can quit and reopen the app at any time. The interrupted recording will automatically start transcribing again.
