Free AI crawler access checker
One line in your robots.txt decides whether AI engines read your site at all. Enter your domain. Pineprompt reads your robots.txt and reports, crawler by crawler, whether the engines behind ChatGPT, Claude, Perplexity, and Gemini are allowed in.
allowed, blocked
Read from No robots.txt found, so everything is allowed by default
Free to use, up to 3 times a day. The result reads robots.txt only; it does not guarantee a given engine honors the file.
Definition
AI crawlers read the open web before they answer.
AI crawlers are the bots that AI companies run to read the open web. Some gather pages to train a model; others fetch pages live to ground an answer. Each one identifies itself with a user-agent your robots.txt allows or blocks.
If your robots.txt disallows GPTBot, OpenAI's crawler will not read your site, so your pages are less likely to inform a ChatGPT answer. The same logic holds for ClaudeBot, PerplexityBot, and Google-Extended. A block you added years ago, or one a plugin added for you, can quietly keep you out of AI answers today.
The checker resolves your domain, fetches /robots.txt, and evaluates each crawler against the rules it finds, reporting whether each one may read your site root.
Setup
Let the AI crawlers in.
Pages an AI crawler cannot read never inform an AI answer. Allow the major crawlers and your content stays in the running. The following robots.txt block allows the most common ones explicitly.
User-agent: GPTBot
Allow: /
User-agent: OAI-SearchBot
Allow: /
User-agent: ClaudeBot
Allow: /
User-agent: PerplexityBot
Allow: /
User-agent: Google-Extended
Allow: /
Allowing a crawler is a choice. Some teams deliberately block training crawlers while allowing the live retrieval ones. The checker shows you exactly where you stand before you decide.

Allowed in, but are you cited?
Letting the crawlers in is the first step. Pineprompt tracks whether the engines then actually name and cite your brand, refreshed daily across all eight engines.
