Can ChatGPT, Perplexity, Claude and Gemini read you?
More and more customers ask an AI assistant instead of searching Google. Check in 20 seconds whether assistants can read your site and what stops them.
We only read public pages, like a visitor. Nothing to install, no access needed.
How a site ends up in AI answers
Nobody can guarantee that an AI assistant will recommend you. We show whether it can read you and what stops it; the rest is down to your content and reputation.
Assistants have search bots
OAI-SearchBot (ChatGPT), Claude-SearchBot and PerplexityBot read your pages to put them in the index they answer from. If robots.txt or the firewall blocks them, you do not show up at all.
And they open pages on the spot
When someone asks something, ChatGPT-User or Claude-User open your page right then, to answer and cite you. They need a fast server and text in the HTML.
They run no JavaScript
AI bots read the HTML the server sends. If the text only appears after scripts run, they see an empty page.
ChatGPT searches through Bing
ChatGPT search and Copilot use the Bing index, Gemini and AI Overviews use Google. A site well indexed there is easier for assistants to find too.
What we check
- robots.txt for every AI bot: search, on request, training
- noindex, nosnippet and other directives that keep you out of AI summaries
- the text visible without JavaScript, exactly as bots see it
- schema.org structured data about the business and pages
- the sitemap, update dates and llms.txt
- how fast the server answers
Track the score automatically, not just once
In a Synux account the check runs on its own, daily from Advanced and weekly on Basic, and you see how many AI bots read your site, how many pages assistants open and how many visitors ChatGPT, Perplexity or Gemini send you.

Can Synux get me recommended by ChatGPT?
We do not promise that and nobody can. We can check whether assistants can read your site, fix what stops them and measure what they actually do: how many pages they open and how many visitors they send.
Should I block GPTBot?
Only if you do not want your texts used to train models. Blocking training bots (GPTBot, ClaudeBot, CCBot) does not remove you from ChatGPT or Claude answers; blocking search bots (OAI-SearchBot, Claude-SearchBot) does.
Does llms.txt help?
A little. In 2026 the big engines do not read it yet; mostly AI agents and coding assistants do. It is cheap to add, but pages being reachable and having text in the HTML matters far more.
What data do you keep?
For the free check we keep nothing about you. If you ask for the report by email, we keep the address, the checked site and the score for at most 12 months, to send the report and, only if you ticked the box, occasional tips.
