AI Checker: check whether your page can appear in ChatGPT, Gemini and Perplexity

AI visibility is the chance that your page is cited in the answers of AI assistants and search engines such as ChatGPT, Gemini, Google's AI Overviews, Perplexity, Claude or Copilot. The first requirement is technical: their crawlers must be able to read the page. In visibility in AI search engines we show which Chilean companies appear in those answers.

The AI Checker reads your site's robots.txt and tells you, crawler by crawler, whether OAI-SearchBot, GPTBot, Claude-SearchBot, ClaudeBot, Googlebot, Google-Extended, PerplexityBot, Bingbot, Applebot and others can access the page. It also checks whether the page asks not to be indexed (noindex) or not to show snippets (nosnippet), how much text it delivers without JavaScript, its headings, structured data, author, date, sitemap and whether an llms.txt file exists.

Search crawlers, such as OAI-SearchBot, Claude-SearchBot or PerplexityBot, read pages to show and cite them in answers. Training crawlers, such as GPTBot, ClaudeBot, Google-Extended or CCBot, collect text to train AI models. You can block training crawlers and still allow search crawlers: that is why the tool shows them separately and only search crawlers count toward the score.

Each checklist item is worth 1 if it is fine (✓), half a point if it can be improved (!) and 0 if it is missing or blocking (✗). The score is the average, from 0 to 100. The llms.txt file and training crawlers are shown for information but do not add or subtract points.

llms.txt is a proposed file, placed at the root of the site, that summarizes the content for language models. It is not required and, for now, no major search engine confirms using it to decide which pages to show. That is why the checker reports it but does not count it in the score.

Not necessarily. According to OpenAI's documentation, GPTBot is used to train models and OAI-SearchBot to show sites in ChatGPT search. If you block GPTBot but allow OAI-SearchBot, your page can still appear in answers. The same applies to Google-Extended: blocking it does not remove you from Google Search or AI Overviews, which use Googlebot.

The tool checks what robots.txt says. Some sites also block crawlers at the server or with a firewall, such as Cloudflare, and that does not appear in robots.txt. To review the rest of the page's SEO, use the SEO Checker. And to see how much traffic changes with AI Overviews, read AI Overviews in figures.

No. This AI Checker does not analyze who wrote the text or whether artificial intelligence was used to write it. It checks AI visibility: whether the ChatGPT, Gemini, Perplexity, Claude and other crawlers can read your page, and whether it has the technical signals AI answers rely on.

Yes. It is free, requires no sign-up and you can check as many pages as you need. It only works with public pages and does not use artificial intelligence to analyze: it reads the site's files, so it does not store or send your content to any assistant.
