Why it matters

Search isn't just Google anymore.

AI Overviews, ChatGPT, and Perplexity all crawl and cite sites differently than classic Googlebot. A clean robots.txt, a valid llms.txt, and correct JSON-LD are now the baseline — not a nice-to-have.

No signup, no paywall

Every tool runs instantly in your browser — no account, no email gate, no upsell.

Built for AI crawlers too

Checks GPTBot, ClaudeBot, PerplexityBot, and Google-Extended alongside classic Googlebot rules.

Fast — no database

Every check runs live against your URL, so results are never cached or stale.
