Free AI SEO and GEO tools for AI search visibility
Three questions decide whether an AI answer engine recommends you: does it name you when a buyer asks, can it read your site, and whose pages is it building the answer from instead. These 18 free AI SEO and GEO tools answer all three, from a four-engine AI visibility checker to an llms.txt validator and a query fan-out tool. All free, and only the citation source radar asks for an email.

Questions
What is free, exactly?
Three things, none of which needs a card. The check on the homepage asks three buying questions on one engine you pick (ChatGPT, Perplexity, Gemini or Grok), with no signup. The 18 tools on /tools need no signup either. Per network and per day, the AI visibility checker allows 12 runs, the AI Overview checker 20 and the query fan-out tool 30. And a free account runs its prompts once on Claude, so you see real answers before you pay. Daily tracking is Starter or Growth.
Is there a free AI visibility checker?
Yes. The AI visibility checker asks one buying question on ChatGPT, Perplexity, Gemini and Google AI Overviews at once and shows, engine by engine, whether the answer names your brand, links your site, or recommends someone else. The ChatGPT, Perplexity and Grok checkers do the same for one engine. No signup.
What are GEO tools?
Tools for generative engine optimization: getting named and cited in the answers AI engines write. The checkers here measure that (who names you, what the engines search, which pages they cite), and the validators and generators fix what stops an engine reading your site.
Do you keep what I check?
Each run is logged with what was typed and what came back, so we can spot abuse (the AI checkers spend money on every run) and see which tools get used. The log is not tied to an account, and nobody emails you unless you ask for a report.
Which one should I run first?
The AI visibility checker. It takes about 20 seconds, and seeing which engines name you usually decides whether the rest is urgent.
What does the paid product add?
The same checks on a schedule: your buying questions tracked daily on three AI answer surfaces (five on Growth), every cited page kept and judged, and the gaps turned into To-dos.
