T9 Rebuilt

The old nine-key T9 keypad with a sentence-aware brain. Click the phone's keys for pure T9 guessing. Or type on your keyboard: your exact letters are used, misspellings get fixed, and words it has never seen still come through. The right side replays the same presses through classic T9, which only ever sees key numbers, so you can see what it would have got wrong.

Why this word

The fixes

Switch one off and retype to see the old frustration come back. Classic T9 has all of these off.

    How the comparison works: classic T9 here uses the same 20,000-word English list ranked by how common each word is, sees only key numbers (never your keyboard letters), with no context, no learning, no typo fixing, no word completion and no Hinglish, as the original 1990s design did. Press counts for classic assume the user knew the right fix, such as how many times to press next, or to spell a word it doesn't know. This is a demo of the ideas, not a measured study.
