Hallucination Detection

How VectorGap detects when AI makes incorrect claims about your brand.

What Are Hallucinations?

AI hallucinations are confident-sounding statements that are factually incorrect. Common examples: - "Brand X was founded in 2015" (actually 2018) - "Brand X costs $99/month" (actually $49/month) - "Brand X integrates with Salesforce" (no such integration exists) - "Brand X is headquartered in San Francisco" (actually Brussels) These aren't lies - the AI genuinely believes it's correct. But they can seriously mislead potential customers.

How Detection Works

During each audit, VectorGap: 1. **Extracts claims** from AI responses (facts, numbers, statements) 2. **Searches your Knowledge Base** for related content 3. **Compares claims to facts** using semantic similarity 4. **Flags contradictions** with severity ratings 5. **Records evidence** for your review Detection requires a populated Knowledge Base. Without reference data, we can't verify claims.

Severity Levels

Detected hallucinations are categorized: **Critical** Major factual errors that could lose sales: - Wrong pricing - Claimed features that don't exist - Incorrect availability **High** Significant inaccuracies: - Wrong company details - Outdated product information - Misattributed capabilities **Medium** Minor issues: - Slightly off numbers - Incomplete information - Dated but not wrong **Low** Potential issues requiring verification: - Ambiguous claims - Partially accurate statements

Responding to Hallucinations

When you find hallucinations: **Immediate:** 1. Document the specific claim and source 2. Verify against your actual facts 3. Check if this appears across multiple providers **Short-term:** 4. Update your website with clear, crawlable facts 5. Create GEO content specifically addressing the incorrect claim 6. Add content to authoritative third-party sites **Ongoing:** 7. Monitor subsequent audits for improvements 8. Set alerts for recurrence 9. Build citations over time AI systems update gradually. Expect 4-8 weeks for corrections to propagate.
