Sitemap.ai is a cloud sitemap generator and website crawler founded in Cincinnati, Ohio, in 2023. From one crawl it creates XML sitemaps for search engines, HTML sitemaps for visitors, llms.txt files for AI systems, and clean markdown for LLM workflows, so teams do not need separate tools for each format. The crawler renders JavaScript, so pages built with modern frameworks are discovered as visitors and search engines see them. Users can save projects, compare crawls to see what changed, and schedule re-crawls to keep sitemaps current without repeating manual work. The free tier allows up to 5,000 URLs per crawl, with 500 URLs per crawl as a guest, and 50,000 URLs per month. Sitemap.ai is built for website owners, SEO professionals, developers, and content teams who need accurate, current sitemaps for search indexing, visitor navigation, and AI discovery. It helps sites get indexed faster, keeps navigation and AI-facing files in sync with the live site, and makes large or frequently changing websites easier to manage from a single crawl.
