The AI keyboard that learns you.
SprintText replaces the keyboard on your iPhone and iPad with one that studies the way you write — your words, your phrases, the corrections you keep making — and then does most of the typing for you.
- It learns your writing, not the average person’s.
- Three characters can become a whole sentence.
- Shortcuts, prediction and learning all run on the device, with no AI service in the loop.
Sprint Shortcuts
Three keystrokes. A whole sentence.
Give any phrase you write often a short trigger. Type the trigger, press space, and SprintText swaps in the full text — matching the capitalisation you used, and putting your cursor wherever you asked it to land.
Interactive demo — a web recreation of the SprintText keyboard, not a screenshot.
Type a three-character trigger, press space, get the whole sentence.
Why it is different
Most keyboards predict what people say. This one predicts what you say.
Autocorrect was built for the average writer. You are not the average writer — you have a job, a tone, a set of sentences you retype every week.
-
It learns you
Sprint Brain is a model of how you actually write: your vocabulary, your recurring phrases, the corrections you keep having to undo. It belongs to you and it gets sharper the more you use it.
Inside Sprint Brain -
You type dramatically less
Shortcuts turn set phrases into two or three characters. Sprint Complete offers whole clauses you have written before. The long messages you dread become a few taps.
How shortcuts work -
It stays useful offline
Expansion, prediction and correction are on-device work. The AI writing actions are a separate, optional layer you invoke on purpose. Turn them off and the keyboard is still fast and still yours.
Our privacy approach
The product
One keyboard, six ideas.
-
Sprint Shortcuts
Triggers that expand into sentences, paragraphs or templates — with date and time placeholders and a cursor marker for where you type next.
Shortcuts -
Sprint Complete
Personalised prediction in the bar above the keys. Not the most likely next word in English — the most likely next words from you.
Prediction -
Sprint Brain
The learned model of your writing, kept on your device, and a dashboard that shows you what it has picked up.
Sprint Brain -
Sprint Trainer
Point Deep Train at writing you have already done and the Brain starts out knowing your voice instead of waiting weeks to learn it.
Deep Train -
My Voice
Rewrite, shorten or soften a draft in your own style rather than a generic assistant voice. An explicit action you invoke, never an automatic edit — and the one part of SprintText we cannot yet tell you works.
AI writing -
SprintText for Mac
The same shortcuts expanding system-wide — in your editor, your mail client, a browser field — from the same library your phone uses.
Mac
Privacy
A keyboard sees everything. This one is built accordingly.
SprintText learns locally by default. Raw typed text is not retained. Sync, when you turn it on, is encrypted on the device with a key our server never sees. The AI actions are off until you switch them on.
- No Full Access needed to type. SprintText types, expands shortcuts and suggests without iOS Full Access. It is requested for haptics and for sync.
- Learning is off until you turn it on. Continuous learning, raw text retention, cloud AI and sync are four separate switches, all off out of the box. What learning does take in is filtered: anything shaped like a password, a key, an email address or a file path is refused.
- Derived signals, not transcripts. What the Brain stores is counts and vocabulary, not a log of your sentences or the apps you typed them in.
- Sync the server cannot read. Your shortcuts and Brain are encrypted on the device before they are uploaded. The key is generated on your phone and reaches your Mac through iCloud Keychain — it never passes through us.
Availability
What is working today, and what is still being built.
SprintText is not on the App Store yet. Rather than promise a date, here is an honest picture of where the product actually stands.
Working today
- The SprintText keyboard for iPhone and iPad — letters, numbers and symbols, autocorrect, auto-capitalisation and the double-space period.
- Sprint Shortcuts: triggers that expand into full sentences as you type, with capitalisation matching and one-tap undo.
- Date, time and cursor placeholders inside expansions.
- The shortcuts panel on the keyboard itself — browse or search your whole library and tap one to insert it, without leaving the app you are typing in.
- The suggestion bar above the keys, offering both your triggers and words learned from your own writing. On a fresh install it falls back to the system dictionary, so it is useful before the Brain has learned anything.
- Sprint Complete: word completion and phrase continuation drawn from what you have actually written.
- Vocabulary learning as you type, gated behind Continuous Learning, which is off by default. A filter drops anything shaped like a password, an API key, an email address, a version number or a file path before it can be learned.
- Sprint Trainer and Deep Train — training on writing you paste or files you choose, entirely on your device.
- The Sprint Brain dashboard, reporting real counts rather than estimates, with insights that offer to turn a phrase you keep retyping into a shortcut.
- The personal dictionary and Privacy Centre, so you can read and delete everything SprintText has learned.
- Sign in with Apple, and signing in to a SprintText account, against the live service.
- Encrypted sync between iPhone and Mac: shortcuts and the learned Brain travel both ways, Brain statistics merge rather than overwrite, and the server only ever holds ciphertext it has no key for.
- SprintText for Mac: system-wide expansion, verified in TextEdit — a trigger followed by a space, followed by punctuation, and mid-sentence.
In development
- My Voice and the other AI writing actions, on iPhone and in the Mac command palette. The code is written but it has not yet run on a machine with Apple Intelligence enabled, so we are not claiming it works.
- Subscriptions. Nothing can be bought yet, on any platform.
Start with one shortcut.
Pick the sentence you type most often this week, give it three characters, and see how quickly you stop typing the long version. Everything else in SprintText builds on that habit.
