Free AI search tools that show you the data, not a score
Two free tools for marketers and site owners: an AI crawler checker that shows whether ChatGPT, Claude, Perplexity and Google can read your site, and a ChatGPT Ads calculator built on real campaign prices. No signup and nothing to install.
AI crawler checker
See whether 14 AI and search bots can get past your robots.txt and your firewall. If a search bot is blocked, you get a corrected robots.txt block to paste in.

Turn a ChatGPT Ads budget into monthly clicks, impressions and cost per lead, using real click prices from Spain and the US.
Estimate my costs →Why our tools show data instead of a score
A 0-to-100 score is easy to screenshot and hard to act on. Two sites can land on the same number for completely different reasons, and the number won’t tell you which fix comes first. So the checker shows the raw result for each bot, the exact rule that applies, and the issues sorted by severity.
The calculator works the same way: real click prices from ChatGPT Ads campaigns, a range that shows how much they move, and a plain list of what it can’t predict. Which brands AI engines actually name in your category is a separate question, and we answer it in the free AI visibility diagnosis.
If AI doesn’t name you, it names a competitor.
The free diagnosis runs real buying prompts on five engines, shows who gets named instead of you and where you can win first.
