Impeccable

Every AI model builds you the same website: a big pale heading, rainbow gradient text, three identical boxes. Impeccable gives the assistant an actual design education. It adds 23 commands you can type into your assistant and 60 automatic checks that catch those generic patterns the moment they appear on your page.

Any time you are building a web page or an app with an AI assistant. Check it before you publish, ask it to improve what it made, or leave the checks running so it flags weak design while you work.

1. Run the command below in the folder your project lives in (in the Terminal: type cd, a space, then drag the folder onto the window and press enter). It works out which AI tool you use, whether that is Claude Code, Cursor, Codex or another.
2. Inside your assistant, type /impeccable init once, so it learns what you are building and who it is for.
3. Build as normal, then finish by typing /impeccable audit to check the result or /impeccable polish to improve it.
