Ask any AI to build a web page and you get the same purple gradient and the same cards inside cards, so Impeccable gives your coding agent a designer’s vocabulary and a slop detector that flags the tells before you ship.
In plain words: an add-on for AI coding tools like Claude Code, Cursor and Codex that teaches them better design. You type commands like “polish” or “bolder”, and a checker scans the page for the telltale signs of AI-made design.
Three systems on board
-
24 design commands in plain words
/impeccable audit, critique, polish, bolder, quieter, distill, typeset and more, so you can steer the look without knowing CSS.
-
A detector that needs no AI
61 rules catch AI tells like purple gradients and bounce animations, plus cramped padding and tiny tap targets; runs with no API key.
-
It checks the agent as it works
On Claude Code, Codex, Cursor, Copilot and Grok Build, an optional hook scans each page edit and reports problems back to the agent.

The best kind of proof: a guy runs it on his brother’s food-delivery site and posts the before and after. “I have no idea how it works,” he says, but the result speaks for itself.
A popular Claude Code creator builds a landing page from almost nothing, picks a look from a gallery of design ‘worlds,’ then clicks parts of the page to get three variations of each. He admits it isn’t a one-shot.
The longer hands-on: building a site from scratch with it, then pointing it at an existing website to see what it would change, with a verdict at the end.
Impeccable Style
The skeptics’ thread. Commenters said the ‘before’ examples looked better than the ‘after’ ones. The creator showed up, agreed the examples were rushed, pulled them, and fixed the bugs people reported.
