How this service works

Output

Example use cases
Decode legacy T9 SMS messages
“I have some old T9-encoded text messages with number sequences like '8428' and '2665' — can you look up what words those T9 numbers represent?”
Predictive text word suggestions
“I'm building a retro phone UI and need to show word suggestions for T9 input — what words match the sequence '7688'?”
Puzzle and game word resolution
“We have a word puzzle where players type numbers on a phone keypad — can you tell me all the possible words that '5669' could spell out in T9?”
