Free tools
Free tools to get found in AI search.
People ask ChatGPT, Claude, and Perplexity instead of Googling. A free toolkit to check and improve how AI answer engines find, read, and cite your site — Answer Engine Optimization (AEO). Built for docs and SaaS teams, useful for any business that wants to show up in AI answers. No signup, no email gate. Each tool runs in your browser or hits an API — that's it.

AEO / GEO Audit for Docs→
Our flagship Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) audit. Score how well ChatGPT, Claude, and Perplexity can read and cite your site.

Authoring
AI README Generator→
Drop in any public GitHub URL — Gemini 2.5 pulls the repo's real metadata and writes a polished README.md with the right sections.
AI-generated install, usage, examples, and contributing sections — populated from your repo's actual language, license, and topics.
Docs Readability Score→
AI cites content that's clear. Paste markdown or a docs URL for a readability score plus Flesch-Kincaid Reading Ease + Grade Level, heading depth, and an AI rewrite of the worst section.
