T9 in the Terminal for Codex, Claude, Gemini

I made a small tool called T9T that sits in front of terminal AI tools like Codex, Claude, and Gemini and fixes obvious prompt typos as you type.

The idea is basically: T9 for terminal AI.

It is local, macOS-only for now, and tries to stay conservative so it does not touch paths, flags, URLs, variables, or other code-like tokens. It uses native macOS spellchecker via NSSpellChecker

I made it because when I’m prompting fast in the terminal, small typos break flow more than they should. Plus any AI will use more tokens to understand what have you typed.

There’s a demo in the repo and the first release is up here: https://github.com/Xsamsx/T9T

Would love honest feedback on whether this feels useful or too niche.
