Features
Everything SprintText does, and how the pieces fit together.
A keyboard, a set of shortcuts, a model of your writing, and an optional AI layer on top. Each part is useful on its own; together they are why you stop typing so much.
The keyboard
A keyboard you would use even without the AI.
None of the clever parts matter if the basics are wrong. SprintText is a complete iOS keyboard first: letters, numbers, symbols, autocorrect, auto-capitalisation, the double-space period, smart punctuation and haptics.
- Three full layouts. Letters, numbers and symbols, laid out where your thumbs already expect them.
- Autocorrect you can dial in. Four levels, from suggest-only to aggressive, because one setting never suits everyone.
- Light, dark or system. Set the keyboard’s appearance independently of the rest of your phone if you want to.
- No Full Access required. Typing, expansion and suggestions all work without granting it.
Sprint Shortcuts
The fastest thing you can do is not type at all.
Give a phrase a short trigger. Type the trigger, press space or punctuation, and the phrase appears. It sounds small until you notice how many sentences you write more than once.
- Capitalisation follows you. Type yyy and you get the sentence. Type Yyy and it comes back capitalised.
- Placeholders. Drop
{date},{time}or{weekday}into an expansion and they resolve as you type.{cursor}decides where your caret lands. - Undo is one keystroke. Backspace immediately after an expansion and your trigger comes back exactly as typed.
- Guard rails. A minimum trigger length stops a one-character typo detonating a paragraph, and word-boundary rules mean yyy never fires inside a word like “myyy”.
- A panel on the keyboard. Cannot remember a trigger? Open the shortcuts panel from the keyboard itself, search your library, and tap one to insert it — without leaving the message you are writing.
- Profiles. Keep more than one library — work and personal, say — and switch which one is active from the Shortcuts tab. Only the active profile’s triggers expand.
Sprint Complete
Prediction that has read your writing, not the internet’s.
The bar above the keys is the second way SprintText saves you keystrokes. It surfaces your shortcuts as you type their triggers, completes words, and offers whole phrases and clauses drawn from the way you write.
-
Your phrases, ranked by you
A generic model suggests the most common continuation in English. Sprint Complete suggests the one you have written before, ordered by how often you actually use it.
-
Three slots, no clutter
Shortcut matches, predictions and corrections compete for the same three slots and are ranked together, so the bar never fills with noise.
-
Corrections that learn
Undo the same autocorrect twice and it should stop happening. SprintText records the reversal as a signal, not a coincidence.
Brain and AI
The learned part, and the optional part.
These are deliberately separate. One is a model of you that learns quietly as you write. The other does nothing at all until you invoke it on purpose.
-
Sprint Brain
Your vocabulary, your recurring phrases, your correction history and how often each shortcut earns its place. On device, and yours.
Inside Sprint Brain -
Sprint Trainer and Deep Train
Feed the Brain writing you have already done — exported notes, drafts, documents — so it knows your voice on day one rather than day sixty.
Deep Train -
My Voice
Ask for a rewrite and get one that sounds like you, because the request carries your learned style rather than a generic tone slider. Written, but not yet verified — see the status below.
AI writing -
SprintText for Mac
Your triggers expanding system-wide in any Mac app that takes text, from the same library your phone uses.
Mac -
Sync across your devices
Shortcuts and Brain travelling both ways between iPhone and Mac, encrypted on the device before they are uploaded, so the server holds only ciphertext it has no key for.
How sync works -
Works with AI off
Switch the AI actions off and you keep the keyboard, the shortcuts, the suggestion bar and the Brain. Nothing core depends on a network call.
Privacy approach
Status
Built, and being built.
Feature lists have a habit of describing intentions. Here is the split.
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.
- Profiles: separate, named shortcut libraries you can switch between, with only the active one expanding.
- 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.
- SprintText Pro, live on the App Store — subscribe from the Plans tab in the app, with a free week on the monthly plan.
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.
- SprintText AI and the combined Pro+AI plan. Not for sale on any platform yet.
