The Problem

Detection tools ask the wrong question

Today's tools ask "was this written by AI?" But that question is becoming irrelevant. Everyone uses AI. The question that actually matters is: "Is what the AI said actually true?" Nobody answers that.

⚖

Lawyers getting sanctioned

518 documented cases of hallucinated legal citations in U.S. courts. Sanctions exceeding $100K. Happening 2-3 times per day.

📊

Reports with fake sources

Deloitte submitted a $440K government report with fabricated academic sources and a fake court quote. They had to issue a partial refund.

💻

Code that compiles but lies

59% of developers ship AI-generated code they don't fully understand. AI code has 1.75x more logic errors than human-written code.
