KT9 Keyboard: Fast Typing

KT9 brings the classic 9-key T9 typing experience to modern Android — fast, accurate and 100% offline. Type with one thumb on the T9 keypad, or switch to a full QWERTY (QWERTZ and AZERTY too). One smart engine powers both.

Everything stays on your device. No accounts, no tracking, no ads, no data leaves your phone.

• SMART PREDICTION
Learns the words and expressions you actually use. Recency, context (n-grams), per-key corrections and time-of-day all improve your suggestions over time — while staying private.

• T9 AND FULL KEYBOARD
9-key T9 with predictive, ABC multitap and a 123 dial-pad, plus a complete QWERTY / QWERTZ / AZERTY layout. The keyboard auto-adapts to the field (phone → 123, email → letters).

• MANY LANGUAGES, OFFLINE
Italian and English built in; download Spanish, French, German, Portuguese, Dutch and Polish. Optional multilingual suggestions and automatic language detection.

• MADE FOR ONE HAND
One-handed mode, adjustable height, gestures (swipe to delete a word, long-press for numbers and accents), and an instant undo of the last auto-correction.

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

• CLEAN, FAST, LIGHT
Built around a compact, memory-mapped dictionary for instant startup and snappy suggestions even after years of use.

KT9 Pro (one-time, optional) unlocks: custom & premium themes, multi language, contact import and customizable punctuation keys. Everything else — full T9, dictionary, learning, grammar correction, abbreviations, backup and languages — is free, forever.
