Impeccable

Teaches AI coding assistants good design, so the websites and apps they build look less generic.

What it does

When you ask an AI assistant to build a website, the results often look the same: the same fonts, the same purple gradients, the same boxes inside boxes. Impeccable is an add-on that gives the AI a designer's rulebook so it avoids those habits.

It adds plain commands you can type to your AI, such as "critique", "polish", "make it bolder" or "make it quieter", so you can talk about design without knowing design jargon.

It also includes automatic checks that spot common design mistakes in a page, which can run without any AI at all.

Who it's for

Anyone building websites or apps with an AI coding assistant, including non-designers who want a more polished result.

Can I use it without coding?

With some setup. You need an AI coding tool such as Claude Code or Cursor. Installing it is a single command, then you use it by typing in plain words. New to this? Start here.
