Apple / utilities / TYPEMASTER - AI KEYBOARD
REVIEW
TypeMaster is a one-developer bet that iOS will let an AI keyboard be useful.
A 99-cent AI keyboard from an indie shop runs into the same wall Gboard and SwiftKey did — and then asks who's paying for the tokens.

Every couple of years a developer looks at the iOS keyboard market, sees Gboard and SwiftKey collecting hundreds of millions of installs, and decides there’s room for a smaller, sharper take. TypeMaster is the 2026 version of that bet — a single-developer AI keyboard from Duy Nguyen, sold for 99 cents, that wraps a writing-assistant layer around a stock QWERTY.
The hard part isn’t writing an AI keyboard for iPhone. It’s writing one that survives Apple’s third-party keyboard sandbox without feeling like a parlour trick. The OS won’t tell the keyboard what app it’s in, won’t let it read the field above the cursor, and will kill and relaunch the extension whenever memory pressure gets interesting. Every AI keyboard on iOS lives or dies on how gracefully it works inside those rules. TypeMaster mostly knows the rules, which is more than half the battle.
The other half is economics. A 99-cent one-time price against a per-request model bill is a math problem that resolves one of two ways — quietly metered, or eventually subscription. The release notes haven’t shown a hand yet.

FEATURES
TypeMaster slots into iOS as a third-party keyboard with "Allow Full Access" required for the AI calls to leave the device. The interface is a standard QWERTY layout with a top suggestion strip and a dedicated AI bar — tap a wand and you get rewrite, shorten, lengthen, translate, and "fix grammar" actions on the currently selected or just-typed text.
Tone presets cover the usual office-survival range: formal, friendly, confident, apologetic. There's a translation pane that handles roughly the language set the underlying model knows, and a small library of canned replies for messages and email. Predictions appear inline as you type, and the cursor-correction gestures behave the way iOS users expect — long-press to drag, two-finger pan on larger screens.
Pricing is the eyebrow-raiser: a $0.99 one-time App Store purchase with no visible subscription on top. That implies either a generous owner eating model bills, a quiet quota nobody has documented, or a future paywall the release notes haven't telegraphed yet.
MISSION ACCOMPLISHED
The design choices are sensible for a solo developer. TypeMaster doesn't try to replace the iOS keyboard's gestures or swipe-type — it sits on top of the system and adds the AI surface the platform won't ship itself. The grammar fix is the most reliable action; rewrites in "friendly" tone land closer to natural English than the equivalent feature in some larger keyboards.
The 99-cent price tag is refreshing in a category where every competing AI keyboard ($SuperKeys, Type AI, RizzGPT and their cousins) defaults to $4.99 a month forever. Even if the model behind it is a cheap one, paying once and owning the install is a real proposition.
ROOM TO IMPROVE
The iOS third-party keyboard sandbox is the whole problem. Apple still doesn't let custom keyboards see the field they're typing into, the app they're inside, or anything before the current text selection — which means TypeMaster's "rewrite this email" only works if you manually select the email body first. The keyboard also gets killed and relaunched aggressively by iOS, so the AI bar sometimes vanishes for a beat after switching apps.
Latency on the AI actions is network-dependent and visible — expect 1–3 seconds for a rewrite on good Wi-Fi, longer on cellular. There's no on-device fallback and no visible model card. The 5-star App Store rating sits on a thin review count, so it's not yet a reliable signal. And the long-term question nobody has answered: what happens when the developer's per-call costs catch up with a 99-cent one-time price?
CONCLUSION
TypeMaster is worth a dollar if you already know what an iOS third-party keyboard can and can't do, and you want AI rewriting available system-wide without renting it monthly. If you've never installed a custom keyboard before, Gboard is still the safer first stop, and SwiftKey covers the predictive-typing case more reliably. Watch the next two updates — that's when the pricing model will tell you whether this is a sustainable indie project or a 99-cent loss leader heading for a subscription.
