Stop Your Site Looking AI-Made: Impeccable, the Free Claude Design Skill
People can spot an AI-made website in about a second, and it's nearly always the same few giveaways. Impeccable is a free, open-source skill (76,000+ GitHub stars) that gives Claude a real design language and catches 61 AI design tells before anyone sees them. How to install it, the one command to run, and how to scan any site
People can tell a website was made with AI in about a second. It isn't the words. It's the look: the same handful of design choices on every AI-built page.
That happens because every model learned design from the same SaaS templates. Without guidance, Claude reaches for the same defaults every time: Inter for every font, purple-to-blue gradients, cards nested inside cards, gray text on colored buttons, and a rounded-square icon above every heading. Visitors have seen it a thousand times, so they stop trusting the page before they read a word.
What Impeccable does
- Gives Claude a design language: one skill with 24 commands for spacing, color, type, layout and motion, the way a professional designer talks about a page.
- Learns your product once. A setup command records who the site is for, what it's for and its voice, so every later command designs for your product instead of a template.
- Catches 61 classic AI design tells, like purple gradients, dark glows, bounce animations and cramped padding, and fixes them.
