User Reviews

I found this app with help from Claude AI, and downloading the on-device Whisper Small model has been a game changer for me. I have a speech impediment and rely on voice dictation daily, and this app understands me far more clearly than Apple's built-in dictation ever has. Being able to use it completely free, unlimited, and offline means a lot to me. A couple of bugs I've run into: I get an orange error popup every time I finish dictating that says something went wrong, but the text comes through correctly anyway. Also, the keyboard doesn't seem to work until I open the Diction app itself first each session — it needs to "wake up" before it'll work in other apps. Even with those bugs, this app has genuinely helped people understand me better. Thank you for building something this good and giving it away for free.
