Free AEO tools for answer engine optimization.
Five tools we use every day on client work — now free. See what AI engines say about you, find what's blocking them and fix it.
These free AEO tools check the three things that decide whether AI engines recommend a local business: whether they name you today, whether they can read your site, and whether your pages give them a clear answer to quote.
AI Visibility Checker
Ask ChatGPT, Google AI Mode, Gemini, Claude, Perplexity and Grok who they recommend in your city — live — and see if you're named, cited or beaten.
Open tool →Answer-Readiness Grader
Score any page 0–100 on 17 AEO checks and get a fix list sorted by impact.
Open tool →AI Crawler Checker
See which of 18 AI crawlers your robots.txt lets in — and which block you from answers.
Open tool →Schema Generator
Build LocalBusiness and FAQ JSON-LD in a minute. Copy, paste, done.
Open tool →llms.txt Generator
Create a clean llms.txt file — with an honest note on what it does.
Open tool →What order should I use the AEO tools in?
Check your visibility first, then fix access, then fix content.
Run the AI Visibility Checker with the service and city your customers search for. If you aren't named, run the AI Crawler Checker to confirm the bots behind ChatGPT, Perplexity and Claude can reach your site. Then grade your most important service page with the Answer-Readiness Grader and work through its fix list. The Schema Generator and llms.txt Generator finish the job by stating your business facts in a format machines read easily. For the full sequence, follow the 30-point AEO checklist.
Free AEO tools FAQ
What is an AEO tool?
An AEO tool checks how answer engines such as ChatGPT, Google AI Overviews, Gemini and Perplexity see your business. It shows whether they name you, whether they can crawl your site and whether your pages are easy for them to quote.
Are these AEO tools really free?
Yes. All five tools are free and none needs a login. The AI Visibility Checker has a limit of a few live checks per day per visitor because each check asks several paid AI engines; the other four have no practical limit.
Which tool should I start with?
Start with the AI Visibility Checker to see whether AI engines name you today. If they don't, run the AI Crawler Checker next to make sure your robots.txt isn't blocking them, then grade your main service page with the Answer-Readiness Grader.
How accurate is the AI Visibility Checker?
It asks the engines live, so the result is a real snapshot of what they answered at that moment. AI answers change with wording, location and model updates, so treat one check as a starting point and repeat the same questions monthly to see the trend.
Do I need llms.txt or schema to show up in AI answers?
Neither is required. Google says no special markup is needed for its AI features, and no major engine has confirmed that llms.txt changes recommendations. Both still help engines read your business details clearly, which is why the generators are here.
Want the monthly version?
Our AEO clients get these checks run on 25–50 real customer questions across five AI engines every month — plus the fixes done for them. Month-to-month, and the co-founder answers the phone.
