CrawlCheck - AI Crawler & Robots.txt Auditor

CrawlCheck is a free toolkit for Generative Engine Optimization (GEO) — making sure your website stays visible when people ask ChatGPT, Perplexity, Claude, Gemini or Copilot about your topic.

What Is It? CrawlCheck audits your robots.txt against 60+ AI crawlers and shows, per path, which AI engines are allowed to fetch your pages. A page that is never crawled is a page that is never cited — CrawlCheck closes that gap for free.

How It Works: Paste your robots.txt or let the live scanner fetch it. CrawlCheck evaluates your policy against its crawler database (built from the open-source ai.robots.txt project and vendor documentation), then returns a verdict for every AI bot, a visibility score, and a prioritized fix list.

Use Cases: SEO teams auditing AI visibility, publishers choosing what to allow into training data, agencies generating compliant AI policies for client sites, developers verifying that a new policy does not accidentally block assistant crawlers.

Products: Auditor — paste robots.txt, get per-crawler verdicts, score and fix list. Generator — pick your visibility strategy per crawler and export a clean, valid policy. Schema — generate FAQ and HowTo JSON-LD that answer engines parse well. Scanner — live-scan your site as 8 AI crawlers with real fetches and one visibility score. Crawler directory — 61 AI bots profiled with operator, purpose, robots.txt behavior and blocking instructions.

Accessibility and Developer Options: Everything runs client-side in the browser — no signup, no cookies, privacy-first analytics. A clean sitemap, llms.txt and per-crawler reference pages make the directory easy to integrate into any workflow.

Company: CrawlCheck is an independent project, not affiliated with any AI vendor. The core tools stay free; optional paid services such as automated monitoring may be added later.
