Why this matters
Blocked bots, invisible business
A single line in robots.txt can stop ChatGPT from ever learning your business exists — many sites block AI crawlers without knowing it.
Search bots vs training bots
OpenAI, Anthropic and Perplexity use separate bots for training and for live answers. This tool checks each one so you can decide precisely.
Fix it in one minute
The generated robots.txt explicitly welcomes every major AI crawler. Upload it and AI assistants can read your site from the next crawl.
