What is Prose Coach?
AI gets the draft moving, but it repeats the same writing habits. Prose Coach marks all 43 of those patterns and returns each fix inside the AI tool you already use โ Claude, Cursor, or Codex โ via a single MCP connector URL that takes about two minutes to set up. Instead of a plagiarism-style score, you get a per-draft coaching brief: the specific lines to change, the rules behind each one, and a three-pass protocol covering line-level habits, repetition and structure, then final voice drift. Edits adapt to the content type, whether that's an email, a cover letter, a blog post, or a report, and intentional voice and rhythm are preserved rather than flattened. Prefer the browser? Paste a draft into the scanner on prose.coach and it returns fixes immediately, no account required. Free tier covers three drafts a day up to 12,000 characters each; Pro is $5/month for unlimited drafts and 200,000-character requests.
