## What doublecheck does, in the publisher's words

A three-layer verification pipeline for AI-generated output. Extracts verifiable claims, finds sources via web search, runs adversarial review for hallucination patterns, and produces a structured report with source links so humans can verify before acting.

AI hallucinations are a model-level problem. No plugin can fix them. But the consequences of hallucinations, acting on fabricated citations, relying on made-up statistics, citing nonexistent case law, can be mitigated by making verification fast and structured.

Doublecheck doesn't tell you what's true. It extracts every verifiable claim from AI output, searches for sources you can check independently, and flags anything that matches known hallucination patterns. You make the final call.
