Hi HN,

I built a free Chrome extension called RadarKit AI SEO Extension. It gives a quick AI visibility audit for the page you are on.

What it checks: AI Visibility: how much text is visible to AI crawlers from raw HTML vs what users see after JavaScript, plus a simple readability score and JS-only content count. AI Access: robots meta tag and robots.txt status for major AI bots (OpenAI and Anthropic bots). llms.txt: detects if llms.txt exists and lets you view it.

If you do SEO, content, or web dev, this helps you spot issues like content hidden behind JS, bots blocked in robots.txt, or missing llms.txt.

I would love feedback on accuracy, UX, and what checks you want next.
