AI visibility tools

Free, instant tools for AI search visibility - grade your AI-readiness, generate the files the answer engines read, and check whether they can crawl you. No signup, nothing stored.

AI Visibility Checker Grade your site's AI-readiness - llms.txt, schema, crawler access, answer formatting - with a score and prioritized fixes. Open tool → llms.txt Generator Build a valid llms.txt - the curated map AI crawlers read. Fill in your site, get a file to copy or download. Open tool → FAQ Schema Generator Turn your questions and answers into valid FAQPage JSON-LD - the structured data AI engines lift into answers. Open tool → AI Crawler Check See whether GPTBot, ClaudeBot, PerplexityBot and Google-Extended are allowed to crawl your site, straight from your robots.txt. Open tool →

Which AI visibility tool should you use first?

Start with the AI visibility checker if you want to know whether answer engines can read and cite your site. Use the AI crawler check when you need to confirm GPTBot, ClaudeBot, PerplexityBot, and Google-Extended are allowed in robots.txt.

If the site is crawlable but the answer still misses you, move to structure: generate llms.txt, add FAQ schema, then compare full monitoring options in the best AI visibility tools guide. For the broader fix list, follow the AI visibility optimization checklist. If you only need a first-pass report, compare the free AI visibility checkers first, then use the AI visibility report template to log the answers. Teams starting with Semrush can read the Semrush AI Visibility Toolkit alternative. Teams starting with Ahrefs can also read the Ahrefs AI Visibility Checker alternative.

AI visibility checking tools by job

The phrase "visibility checking tools" covers several jobs. Separate them before you compare tools, because crawler access, AI-readiness, and answer visibility are different signals.

Can AI crawlers read my site?

Use the AI crawler check first. It reads robots.txt and shows whether GPTBot, ClaudeBot, PerplexityBot, Google-Extended, and other answer-engine crawlers are allowed.

Check AI crawler access

Is my site structured for AI answers?

Use the AI visibility checker. It grades crawl access, structured data, llms.txt, answer formatting, and the page signals that make a site easier for answer engines to cite.

Run the AI visibility checker

Do I have the files and schema AI systems expect?

Use the llms.txt generator and FAQ schema generator. They help turn your most important pages and questions into clearer machine-readable entry points.

Generate llms.txt

Do AI engines actually name my brand?

Move from site readiness to answer visibility. AEO tracking software monitors saved buyer prompts over time and shows whether engines name you, who they name instead, and what changed.

From free checks to ongoing AI visibility tracking

Free tools are best for the first pass: can answer engines crawl the site, can they extract the right facts, and are the key pages structured clearly enough to cite? Ongoing AI visibility tracking answers the operating question: are you gaining or losing presence across saved buyer prompts, engines, and competitors?

Use the AI visibility pillar for the measurement framework, the best AI visibility tools guide for commercial comparison, and the AEO tracking software checklist when you are ready to move from one-time checks to a monitor.

Frequently asked

What are AI visibility tools?

AI visibility tools help teams check whether answer engines can read, understand, mention, and cite a brand. Some tools test site readiness, such as crawler access and schema. Others monitor the answer itself: whether ChatGPT, Gemini, Perplexity, Claude, or Google AI Mode name the brand for buyer prompts.

What is a visibility checking tool?

A visibility checking tool gives a first read on whether your brand or site is visible to AI systems. The useful distinction is site visibility versus answer visibility. Site checks test crawlability and structure. Answer checks test whether AI engines actually name your brand and competitors.

Which AI visibility tool should I use first?

Start with an AI crawler check if you are unsure whether AI bots can access your site. Then run an AI visibility checker to grade readiness signals such as schema, llms.txt, and answer-friendly content. If the site is readable but your brand is missing from buyer prompts, move to AEO tracking.

When do I need AEO tracking software instead of a free checker?

Use a free checker for a baseline. Use AEO tracking software when you need recurring prompt monitoring, share-of-voice movement, competitor changes, alerts, and proof that content fixes changed the answer.
