AI Crawler Access Check

What does AI say about you?

The full check: your real buyer questions across ChatGPT, Claude and Perplexity — mentioned, recommended and cited, with the answers as evidence.

First check free · 3 minutes

Every tool here costs nothing to run — for you and for us: no AI calls, just a few requests to your own site. That is why they can stay free and unlimited.

Why free tools?

Access comes before visibility

Most companies that are missing from AI answers never got as far as being read. A blocked crawler, a JavaScript-only page or a missing entity is a five-minute fix once you can see it — so we give away the checks that show it, and charge only for the part that actually costs money: asking the engines what they say about you, every week.

What happens with my domain?

Each tool fetches a handful of public pages from your site the way a crawler would, computes the result, and caches it for a few minutes so a shared link loads fast. No account is created and nothing about you is stored beyond that cache.

Questions about the free tools

Are the free tools really free?

Yes. Each tool runs instantly with no account, no signup and nothing stored; the checks are the same ones the Reflexa page check runs, cut down to a single question each.

What do the free tools check?

Five things AI needs from a website: whether AI crawlers (GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and others) may read it, whether llms.txt is valid, what a page looks like without JavaScript, whether the homepage's JSON-LD tells AI who the company is (13 checks), and whether a bot in your logs is genuine.

Is the free tool the same as the full AI check?

No. The tools check what AI can read and understand. The free page check reads every public page the way ChatGPT, Claude and Perplexity read it — 22 checks — and shows what to fix first.
