AI crawler checker
The AI crawler checker tests whether GPTBot, ClaudeBot, PerplexityBot, and other AI crawlers can reach a URL, by reading robots.txt and fetching the page as each crawler.

This checks one page. The same problem usually repeats on every page built from the same template. Plans start at $14.99 a month.
How to use the ai crawler checker
- 1
Paste an address
A full URL or just a domain. We add https:// when it is missing.
- 2
We fetch it live
Our server requests the page now, the way a crawler would, and records what came back.
- 3
Read the evidence
Every result shows the value we read, so you can see why it passed or failed.
- 4
Fix and check again
Change the page, run it once more, and ship when the second run agrees.
What this does not measure
We would rather say what a tool cannot see than let a clean result mislead you.
- It fetches the page as each crawler from one location at one moment. A crawler blocked in another country, or tomorrow, is not visible here.
- A block is not always a defect. Blocking a training crawler in robots.txt is a valid opt-out and the tool labels it as one.
- It cannot see whether the crawler already has the page in an index from before the block was applied.
- Perplexity-User and ChatGPT-User fetch only when a person asks, so they may be allowed while the indexed crawlers are not.
Want the full picture?
This tool answers one question. A full audit runs every check on a page, scores it, and gives you a short list of what to fix first.
