AI-Signed is a trust verification platform that runs 43 automated checks across identity, security, content, reputation, and AI readiness. Verified sites earn a trust badge that AI chatbots and search engines can read when deciding which sources to recommend.

How does AI-Signed help with AI chatbot recommendations?

AI chatbots like ChatGPT, Perplexity, and Google AI prioritize verified, trustworthy sites when recommending sources. AI-Signed verifies your site across 43 trust signals — security headers, structured data, llms.txt, and more — so AI agents can confirm your site is legitimate and cite it over unverified competitors.

How much does AI-Signed cost?

AI-Signed offers three tiers. Verified is $5.99/mo for the trust badge and 43 automated checks. Verified + GEO Citation Checker is $13.98/mo — the base Verified plan stacked with the $7.99/mo GEO add-on that measures which LLMs cite your brand. Verified Business is $19.99/mo and includes the GEO Citation Checker with expanded monthly quotas. You can run a free instant scan before subscribing.

What is the GEO Citation Checker?

The GEO (Generative Engine Optimization) Citation Checker runs auto-generated, natural-language prompts against Claude with live web search, then reports whether your domain is cited, whether your brand is mentioned in the answer, and which competitor domains are cited most often. Available as a $7.99/mo add-on to Verified, or included with Verified Business.

What trust grade levels does AI-Signed offer?

AI-Signed assigns four trust grade levels based on your score: Platinum (A+, 95-100 points), Gold (A, 85-94 points), Silver (B, 70-84 points), and Bronze (C, 55-69 points). Your grade determines the badge level visible to visitors and AI agents.

What checks does AI-Signed perform?

AI-Signed runs 43 checks across 5 categories: Identity Verification (DNS ownership, WHOIS, payment identity), Technical Security (SSL, DNSSEC, security headers, HTTPS), Content Trust (privacy policy, terms of service, contact information), Reputation Analysis (domain age, blocklist checks, Safe Browsing), and AI Readiness (robots.txt, structured data, llms.txt, AI plugin compatibility).
