Your audio never leaves your device

No word cap
Same email. Three ways to write it.
Saved Phrases or your voice. Both beat typing.
Tap a Saved Phrase, or talk it through. The email lands formatted, and the keyboard stays where it is.

Simulation with a made-up email. Typing: 38 words per minute. Voice: 150 words per minute. Tap timing is assumed, not measured.
Email: Hi Alex, Thanks for checking in. I’ll send the updated plan tonight so we can review it together before the meeting tomorrow. Best, Nick
The thumb-typing tax costs you more than time.
3xIn a Stanford study, people entered text about three times faster by speaking than by typing on a phone. Your thumbs are the slow part. Stanford study: 153 vs 52 words per minute. Not a Cofactor benchmark.
Replies that wait.
The real answer waits for “when I’m at a laptop,” and it nags at you all day.
Ideas that fade.
Half the idea is gone by the time the first line is typed.
Cleanup you never asked for.
Built-in dictation keeps every false start. Some cloud apps upload your audio and limit free dictation.
You shouldn’t have to pay by the word or hand over your voice to be heard.
Say it once. It comes out ready to send.
All included free.
Emails and replies in seconds.
Mail gets a greeting and a sign-off. Messages stays casual. Change your mind mid-sentence and only the correction lands.
Writing that sounds like you.
Your names and jargon spelled right, in the tone you pick, with word predictions on the iPhone keyboard.
Every thought kept.
Every take is saved before it’s transcribed. After a one-time language download, it works with zero bars.
We kept losing good thoughts to bad typing too.
So we built a keyboard that keeps your voice private and saves every take.

A voice keyboard for iPhone and Mac that writes what you meant.
Cofactor is a free voice keyboard for iPhone and a dictation app for Mac. Tap the mic in any app and talk normally. It writes clean, punctuated text, keeps only your corrections, turns spoken lists into bullets or numbered steps and adds an email greeting and sign-off. It runs on your device, works offline after a one-time language download and never sends your audio anywhere. Pro adds the Parakeet speech engine, Rewrite It for Me, search by meaning, writing rules for each app and website, voice insights and coaching, and Siri actions. You say it once, and it’s already written.
See it clean up a real sentence.
Pick an example. On the left is what the mic heard. On the right is exactly what Cofactor wrote, taken from its own test cases.

What Cofactor wrote
Lists come out as plain-text lines that start with “-” or “1.”, so they paste cleanly into any app.
Start free. Upgrade if you want more.
Everything you need to talk instead of type is free, with no time limit.

Questions before you choose
What stays on my device?
Your audio stays on your device. Dictation and cleanup run locally by default. Optional sync uploads encrypted text and settings. Team sharing, the Automation API and an external polish provider send only the text you choose to share.
Does Cofactor work offline?
Yes. Download your speech language or model once, then dictate and clean up text offline. Sync, team updates, billing and external polish providers need internet.
How is it different from Apple Dictation?
Cofactor adds writing tones, saved phrases, personal vocabulary and saved-audio Retry. See your words in the keyboard preview, then insert the cleaned text when you stop.
Which apps can I use it in?
On iPhone, use Cofactor in apps that allow third-party keyboards, including Messages, Mail and Slack. Password and phone-number fields use Apple’s keyboard. On Mac, dictate into your active app or copy the result if insertion isn’t supported.
Does it work on iPhone and Mac?
Yes. The iPhone beta needs iOS 26 or later. Mac needs macOS 13 or later on Apple silicon. Optional encrypted sync connects your personal data across both.
Which languages does it support?
English, Spanish, French, German, Italian, Brazilian Portuguese, Simplified Chinese, Japanese and Korean on both devices. iPhone Auto mixes English and Spanish. English has the full cleanup and custom writing modes.
What do I get for free?
Unlimited on-device dictation, the iPhone keyboard, built-in tones, vocabulary, saved phrases, Notes and History. Retry, backup and export stay free. Optional encrypted sync uses a free account. There’s no word cap or trial clock.
What does Pro add?
Pro adds the Parakeet speech engine for the most accurate dictation, Rewrite It for Me on iPhone, search by meaning across everything you’ve said, thinking-session summaries and shareable updates, voice insights and coaching on your most-used words, filler words and pace, Siri actions and Saved Phrase variables, and writing rules for each app and each website. Everyday dictation, the keyboard, cleanup and Redo stay free, and your recordings and transcripts are always free.
What does Team add?
Pro for every seat, shared vocabulary and phrases, team formatting defaults, member roles and central billing. It’s $6 per seat each month on the website, with a minimum of 3 seats.
Can I try Pro and cancel?
The website offers eligible new subscribers a 30-day trial. Apple shows its own offer before you buy. Subscriptions renew automatically; cancel before renewal, at least 24 hours ahead with Apple. Your recordings, notes and history stay yours.
Stop typing it out. Say it once.
TodayYou thumb out a reply at a red light. The light turns green, the guy behind you leans on his horn, and you hit send on “sounds good, see yuo at 7 ducking.” Then the blue lights show up in your mirror. Day ruined.
With CofactorYou say it once, and it lands clean in whatever app you’re in. The email has a sign-off, the list is a list, and your voice never leaves your phone. You pull away from the light smiling.
Launching soon on the App Store.
