CrawlCheck (crawlcheck.io, owned and operated by VSNARY per its terms of service) checks whether AI systems can read a website: it shows what ChatGPT, Claude, Perplexity and Google crawlers actually get from a site and returns a free A-F grade with every problem named. It offers scheduled monitoring with regression alerts, paid fixes, executive reports, free tools (agent lens, robots.txt and llms.txt audits, Googlebot check, entity map validator), a site registry, datasets, a browser extension, and a developer API with MCP server, OpenAPI, and npm/PyPI SDKs.
