Brand Disambiguation Check
Also known as: AI Entity Linking Checker, Entity Collision Check
Paid-exclusive Radar tool that checks whether AI engines link your brand to the correct real-world entity or confuse it with a same-named company, person, or product. Extracts ground truth from your site and llms.txt, queries ChatGPT, Claude, Gemini, and Perplexity, and flags named-entity-disambiguation failures by severity. Runs inside the Radar dashboard for paid users, with a public explainer (labeled example, no free run) at /tools/brand-disambiguation.

Why does ChatGPT confuse my company with another?
ChatGPT confuses your company with another because it links your name to the wrong entity in its internal knowledge graph. This is brand disambiguation failure, not hallucination: the facts it returns may be accurate, just about a different company that shares your name. The fix is stronger entity signals, not more content.
Why does ChatGPT say wrong things about my company?
ChatGPT hallucinations about your company come from three sources: outdated or thin training data, confusion with similarly-named companies, and absence of authoritative web sources for ChatGPT to ground its answers in. Each source has a different fix.
