AI Fact-Check

Find what AI assistants get WRONG about a local business. Asks ChatGPT and Perplexity live (with web search) about the business's hours, address, phone, and category, then verifies each stated fact against Google Business ground truth. Returns a severity-ranked list of conflicts (with the AI's value vs. the trusted value and source) plus discrepancies to check. Conservative by design: a claim with no trusted source is 'unverifiable' (never an error), and a conflict is only counted when it reproduces across engines — so it won't cry wolf. Call this when a user asks whether AI has the right info about a business, or 'why does ChatGPT say we're closed'. Takes ~15-30 seconds. Price: $1.49 per delivered check.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| businessName | string | yes | The local business to fact-check |
| location | string | yes | City and state/region, e.g. "Cincinnati, OH" |
| businessType | string | no | Optional category anchor, e.g. "restaurant" — helps resolve the business; not required |
| website | string | no | Optional: the business website — if an AI answer cites this domain, a mismatch is treated as a possibly-stale discrepancy rather than an error |
