An AI visibility checker that runs in the browser

Lumi GEO is a free Chrome extension that analyzes a page as AI crawlers see it, comparing the server-sent HTML with what renders in the browser and flagging text that only appears after JavaScript runs. It reports a score out of 100 across SEO, GEO, AEO and AI view pillars, lists prioritized fixes with point values, and provides copyable code such as JSON-LD and an llms.txt template. The free tier offers five analyses a day with no account, and the extension states that no browsing data is sent.
