Coda One
Coda One is a browser-based AI writing suite for people who want to review and revise drafts in one workflow. Its AI Detector screens text for patterns associated with AI-generated writing and highlights sentences for review; the Humanizer rewrites text in selectable styles, the Rewriter paraphrases it, and the Grammar Checker checks language errors. Users can move text between these tools and access the four tools through a Chrome browser extension. The detector is available at no charge without a daily scan limit, subject to a word limit per check. The writing tools have limited free daily uses, with paid monthly plans for higher usage. Coda One is aimed at students, writers, marketers, and other professionals working with written content. It is accessed through a web browser, with an extension that brings the writing tools into compatible web pages.
