Free tools for the age of AI search

Search is changing. Instead of scanning ten blue links, more and more people ask ChatGPT, Perplexity, Gemini or Google’s AI Overviews a question and act on the answer. To be part of that answer, your site has to be easy for AI systems to read, understand and trust. These free tools handle the technical groundwork — the files and structured data that make your content legible to machines — so more of your pages can be surfaced and cited.

Every tool here runs entirely in your browser. There’s no sign-up, nothing is uploaded to a server, and the output is yours to copy or download. They’re the same fundamentals Suparank automates inside the product: when you’re ready to measure how AI actually describes your brand and fix what’s holding you back, the full platform takes it from there.
