Meelu
Meelu is a marketing software project with free browser-based SEO tools and a desktop AI marketing agent in development. Available tools include a technical site audit that crawls up to 100 pages and checks crawlability, indexing, metadata, structured data, internal links and AI-crawler access; a broken-link checker; keyword clustering; readability and text-similarity checkers; and an AI-content detector. The tools provide reports or downloadable CSV results, and the public audit tools require no account. The planned desktop agent is intended for marketers, SEO specialists and website-owning teams. The vendor describes its future functions as local site crawling and audits, marketing-data analysis, outreach drafting and social listening, with user approval before external actions. The site currently labels the desktop agent as in development, so these planned capabilities should not be treated as a finished product.
