Use your voice in any app — prompt ChatGPT, Claude, and OpenClaw, or message on Telegram and WhatsApp. Diction works everywhere you type.
Customizable keyboard. Add keys, rename them, resize and reorder. Toggle visibility so keys only appear in edit mode. Make it yours.
Tap-to-fix. Select a word and smart alternatives appear: spelling fixes, grammar corrections, better phrasing. One tap to accept.
Save to My Words. Teach Diction your names and jargon for better accuracy over time.
On-Device: voice to text that runs locally on your iPhone. Offline dictation. Audio never leaves your device.
Self-Hosted: run your own speech recognition server. Your network, your data, your models. Open-source server on GitHub.
Diction One (paid subscription): highest accuracy cloud models plus the best on-device model. Zero setup. AI Companion: turn natural speech into polished text, edit or rewrite by voice, translate on the fly. Select text and say what to change. Free trial included.
Transcription history with search. Copy, retry, and review past dictations. Failed transcriptions retry automatically so nothing gets lost.

Works amazing. Especially on job sites with equipment running in the background. I'm using it now to leave this review. It looks very professional when texting with clients because it corrects my bad grammar and corrects some of my Southern accent. 10 out of 10 would recommend!
Goodbye Siri Dictation
dkshaw
I've grown to be frustrated with Apples Siri and the dictation functionality. Too many times it gets it wrong with bad punctuation. Until diction arrived my workflow was to dictate on mobile using ChatGPT, copy it, then go into the app and paste my text. Too cumbersome! now with diction I self host whisper and I can seamlessly dictate. Love it.
Interesting idea

I like the concept and provides multiple options for the user
Better than Wispr Flow highly recommend

This app is truly incredible. It has all your bells and whistles and really great features that I really like and the local model Parakeet is very accurate. I used to be a Whisperflow user, and I just got sick and tired of having to context-switch and leave my app, and I feel like with this app, it's a lot more frictionless. Since the model locale you don't have to worry about your voice data being sent to a server if you just leave your microphone on all the time. I'm super satisfied with this app.
