Source Authority | Markup AI

AI Visibility

Give every claim a source AI search trusts. This agent finds statements that lack the credibility signals AI search engines look for.

Part of Markup AI’s AI-search optimization suite — GEO/AEO (generative / answer engine optimization) for visibility in ChatGPT, Perplexity, and Google AI Overviews.

What it catches

Unattributed statistics, vague research references, and unnamed experts — the kind of content AI-powered search treats as low-trust. Writers get a list of exactly where to add citations or attribution. The Claims covers the complementary problem: risky, unsubstantiated assertions.

Why it matters

Credibility signals are ranking signals now. Named sources and real citations are what separate content that gets cited from content that gets ignored.
