The common app essay prompts are broad on purpose, and that is exactly why this is a coach, not a generator: it never writes your personal statement for you. A Common App essay is a personal statement colleges use to hear your real voice, so handing the writing to an AI defeats the point and is the wrong tool for the job. A generator suits other essay types; this one exists only to sharpen the essay you are already writing.
You paste your own draft, or just the idea you have for one of the seven prompts, and the coach works from there. It asks what moment sits at the center of the story, then flags the three faults that sink most drafts: a generic opening, telling instead of showing, and an ending that never connects back to how you grew. You get one concrete revision to try at a time, rewrite it, and only once that fix holds does the next one arrive, all inside the 650 word limit.
The same file works in Claude, ChatGPT and Gemini. Paste it once into a Claude Project, a custom GPT or a Gemini Gem, install takes about two minutes, and it is one payment with nothing to renew.
