KT9 T9 Keyboard: Big Keys

KT9 brings classic 9-key T9 typing to Android — fast, accurate and 100% offline. With big, readable keys, built also for anyone who struggles to hit the tiny keys of ordinary keyboards.

Type one-handed on the T9 keypad, or switch to a full QWERTY (QWERTZ and AZERTY too). One smart engine behind both.

Everything stays on your device. No account, no trackers, no ads: your data never leaves the phone.

• EASY TO READ AND EASY TO HIT
Six sizes for the key text, adjustable height and key spacing, your choice of long-press duration and a simplified look for fewer symbols on screen. QWERTY has its own text size and spacing. Works with any theme.

• PREDICTION MEASURED, NOT PROMISED
Quality verified with a repeatable benchmark on real texts: in Italian, 96% of words come up as the first suggestion and 100% within the first three. The engine learns the words and phrases you actually use — recency, context, per-keystroke corrections and time of day — and keeps it private.

• T9 AND FULL KEYBOARD
9-key predictive T9, ABC multitap and a 123 keypad, plus a full QWERTY / QWERTZ / AZERTY. Four keypad layouts: Modern, Large, Classic phone and Xperia. The keyboard adapts to the field (phone: 123, email: letters).

• SIXTEEN LANGUAGES, OFFLINE
Italian and English included; download Spanish, French, German, Portuguese (Portugal and Brazil), Dutch, Polish, Romanian, Turkish, Croatian, Indonesian, Danish, Hungarian and Arabic. Multilingual suggestions and automatic language detection (optional).

• BUILT FOR ONE HAND
One-handed mode, adjustable height, gestures (swipe to delete a word, long-press for numbers and accents) and instant undo of the last correction. Gestures can be turned off if your finger rolls.

• YOUR DICTIONARY, YOUR RULES
Add your own words, favorites, abbreviations (shortcuts that expand as you type) and a block list. Back up and restore everything as a local JSON file. Full Privacy mode disables all learning.

• EMOJI, VOICE AND TRANSLATION
Over a thousand emoji with people, flags and skin tones (with KT9 Pro; hundreds are free). Voice dictation that runs on the phone, with no audio sent anywhere. Offline translation of the sentence you just wrote (beta, with KT9 Pro).

• CLEAN, FAST, LIGHT
Compact memory-mapped dictionary: instant startup and snappy suggestions even after years of use.

KT9 Pro (one-time, optional) unlocks: custom and premium themes, customizable keys in every layout (everything except letters, space and punctuation), the full emoji set, offline translation, multilingual suggestions and automatic language detection, and contact import. Everything else — full T9, dictionary, learning, auto-correction, abbreviations, backup, dictation and languages — is free, forever.
