robots.txt Validator
Paste a robots.txt — or give us a domain and we fetch it — then see the broken lines and which AI crawlers it actually blocks.
Paste mode is offline: nothing is uploaded and nothing is fetched. It reads the text in the box, and it cannot tell you whether the paths exist.
Paste a robots.txt on the left and the findings appear here.
