About Prose Coach

Prose Coach is a text file you load once into ChatGPT, Claude, Cursor, or Gemini's system prompt. It forces the model to vary sentence rhythm and structure as it writes, so the flat, predictable patterns AI detectors flag never show up in the draft. Built for anyone who uses an LLM for writing and is tired of re-prompting or manually de-flagging output.

What makes it different

It works inside the system prompt as the model generates text, rather than editing or paraphrasing after the fact, and it includes voice-preservation valves so the fix targets the model's generic defaults, not the user's actual style.
