Exactly what you said. Cleaned up.

Fast, accurate transcription, then the cleanup you would do by hand: fillers gone, grammar fixed, lists formatted, your names spelled right. And when the text is already there, just say what to change.

A keyboard that understands you.
Built from the ground up.

Keys

Keys that learn your aim

The keyboard learns where your thumb actually lands, so fewer wrong letters get through in the first place.

Typing intelligence

Knows what you meant to type

Autocorrect, word completion and next-word suggestions, written from scratch instead of borrowed from iOS. It learns your names and jargon, and it all runs on the phone.

Speech AI

Loved by the people who use it.

4.9Read the reviews on the App Store
“Even apart from self-hosting, Diction is the best keyboard I have used so far. The combination of a full keyboard and an excellent dictation function is a real productivity gain.”
“I have a speech impediment... 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.”
“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.”
“Works amazing. Especially on job sites with equipment running in the background... It looks very professional when texting with clients because it corrects my bad grammar and corrects some of my Southern accent.”
“Until diction arrived my workflow was to dictate on mobile using ChatGPT, copy it, then go into the app and paste my text... now with diction I self host whisper and I can seamlessly dictate. Love it.”
“If you have a Mac, you can set up the backend very easily... The front end is already a very polished interface... And you can control your own privacy.”
“Finally, a voice keyboard that actually understands me... It works flawlessly across all my apps, and having the option to run it completely offline is a huge bonus.”

Diction Cloud.
Hard to beat.

We run the GPU servers ourselves. Your voice is transcribed there and thrown away, never stored. Running the hardware also keeps costs down, which is how the price stays fair and below what most dictation apps charge.

Good questions.

Is Diction free?

On your iPhone and on your server, yes. Free forever, no word limits, no account. Diction Cloud is the paid option at $5.99 a month or $59.99 a year, and you can try it free first.

Is it a full keyboard, or just a mic?

A full keyboard. QWERTY with the layout for your language, autocorrect that looks at where your finger landed, word completion and next-word suggestions, all computed on your iPhone. The mic sits above the keys, one tap away in every app.

Does it work in every app?

Pretty much anywhere you can type: Messages, Mail, Slack, Notes, your browser. Two exceptions come from iOS itself. Password fields always get the system keyboard, and a few apps block custom keyboards.

Does it work offline?

Yes, in on-device mode. Download a speech AI once and dictate on a plane, in a tunnel, anywhere. Diction Cloud and self-hosted need a connection, because that is where the speech AI runs.

Is my voice stored?

No. On-device, your voice never leaves the phone. Self-hosted, it goes to your server and nowhere else. On Diction Cloud it is transcribed and thrown away.

Why does the keyboard need Full Access?

iOS asks for it before any keyboard can use the network, and Diction needs the network to reach the speech AI. That is all it is used for.

Which languages does it speak?

99 for dictation, with auto-detect if you switch between them. 25 European languages get the most accurate engine.

Will it get my name right?

Add it to My Words once, along with your colleagues, brands and jargon, and Diction spells them your way from then on.

Can I edit text by voice?

Yes. Hold the mic and say what you want: "make it a list", "translate it to Spanish", "remove the last sentence". The text that is already there changes.

What is self-hosting?

You run the Diction server on a machine you control, and the app sends your voice there instead of the cloud. It is open source, it runs in Docker, and pairing is one QR scan.

Do I need a GPU to self-host?

It helps. An NVIDIA GPU gives the fastest results. No GPU? The smaller Whisper models run fine on a CPU.

Can Writing Tools use an LLM I run at home?

Yes. Point the server at any OpenAI-compatible endpoint, like Ollama, and Writing Tools run on it, free.

Is there an Android or Mac app?

Not yet. Diction is iPhone first, and that is where the work goes right now.

How do I cancel?

The same way as any App Store subscription, in your Apple ID settings. On-device and self-hosted keep working, free, after you cancel.

Your keyboard is waiting.

Free on your iPhone and on your server. Works in every app.
