New: a much more reliable keyboard. Fewer wrong keys, autocorrect that catches far more typos, and next-word suggestions worked out on your iPhone.

Dictate messages, emails, and notes. Works in any app you type in: Notion, WhatsApp, Slack, and everywhere else. No switching, no copy-pasting.
Smart QWERTY keyboard. Autocorrect fixes typos as you type and splits run-together words. Word suggestions appear above the keys. Correct a suggestion back once and Diction stops offering it.
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.
Transcription history with search. Copy, retry, and review past dictations. Failed transcriptions retry automatically so nothing gets lost.
The Diction app has zero analytics, zero tracking, and zero data collection. AES-256-GCM encryption. X25519 key exchange.
Diction One (paid subscription): highest-accuracy cloud speech models and Writing Tools. Turn natural speech into polished text, edit or rewrite by voice, translate on the fly. Select text and dictate what to change. Free trial included.
On-device mode: runs locally on your iPhone with no internet needed. Audio never leaves your device.
Self-hosted: run your own speech recognition server. Your network, your data, your models. Pairing is a scan: your server prints a QR code, you point the app at it, and keys rotate themselves after that. Writing Tools works there too, free, because it is your hardware. Open-source server on GitHub.

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.
Absolute amazing, secure, voice to text application!

I've been using this non-stop for two or three months now, and this is the exact application I wanted for this process. I wanted to be able to do it completely on device or through my own hosted voice transcription server, which this offers as well as extremely powerful. Or you can get really Powerful Third-party hosted solution that you can pay a small amount for. I'm extremely security and privacy conscious, so I wanted things I can control locallyThe developer has added many new options over the months, including a newer model called NVIDIA Parakeet that is Is still extremely accurate, but smaller and significantly faster than the largest whisper model that was originally the best one in terms of accuracy.This works extremely fast, even on device, on both my iPhone 17 Pro Max and my iPad Mini 7th generation (which uses the same CPU/SOC as the iPhone 15 Pro) which means it should be extremely fast on any modern iPhone or iPad.Earlier versions had some minor bugs, but they have been fixed and the developer has been very responsive to the bug reports that I've made and they are working diligently to make this application better and better by day!
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.
Perfect dictation even for my southern accent!
OMGitsMiniMe
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!
