## About

Coda One is a small set of AI writing tools built around one loop: check a draft, then fix what the check finds. The AI Detector is free with no daily limit and no signup, and it marks the specific phrases that read as machine-written instead of just giving a score. Alongside it are an AI Humanizer with 9 writing modes, an AI Rewriter with 8 tones, and a Grammar Checker, in the browser and a Chrome extension. The writing tools are free for 3 runs a day; paid plans from $9.99/month.
