Questions people ask
What is ChatSniff?
ChatSniff is a free website checker. Paste an address and it inspects technical health, SEO, visibility in AI assistants (ChatGPT, Claude, Gemini, Perplexity), security hygiene, speed, UX and content — then explains each problem in plain words and drafts the fix.
Is it free?
Yes. During the launch everything is free, with no sign-up and no credit card. If paid plans ever come, they will be announced clearly beforehand.
Does ChatSniff attack my website?
No. It reads what any visitor or search engine can see. Checks for exposed files (.env, .git…) only run on sites whose owner proved ownership. ChatSniffBot respects robots.txt.
What does AI Sniff check?
Whether AI crawlers are allowed in robots.txt, whether your content is readable without JavaScript, whether AI can tell who you are and what you offer, and the emerging agent standards (Markdown versions, llms.txt, MCP). Each item says how strong the evidence is.
Can ChatSniff fix the problems?
Yes: it writes the fix for you — meta descriptions, titles, robots.txt, structured data, security headers — with a before/after preview. You approve, then copy or download it. Nothing is ever published without you.
