About Zen-O-Raen

Zen-O-Raen is a web-based checker that tests whether AI crawlers and search engines can access a website. It covers major AI platforms such as ChatGPT, Claude, Perplexity, Grok and Gemini, as well as Google and other search engines, and flags robots.txt or CDN settings that silently block crawlers.

It also checks a domain's SPF and DMARC DNS records. Missing records mean anyone can send email pretending to come from the domain, which puts its users at risk of phishing.

The tool also explains which bots to allow or block. AI training bots such as GPTBot, Google-Extended, DeepSeekBot and Grok collect content to train models, and allowing or blocking them is a business decision. AI search bots such as OAI-SearchBot, PerplexityBot and ClaudeBot show content in real-time AI search and are usually worth allowing.

It is free to use and requires no signup, which suits site owners who want a quick look at their crawler and email configuration.
