Every Claim. Checked.
We extract individual facts from AI responses and verify each one independently.
How Fact Verification Works
A three-step pipeline that turns raw AI responses into confidence-rated facts.
Claim Extraction
Each AI response is broken into atomic factual claims — individual statements that can be independently checked against other models.
Cross-Reference
Claims are matched across models using semantic embeddings and cosine similarity. If two models say the same thing in different words, the system catches it.
Color Coding
Each claim gets a confidence level: green (verified by 3–4 models), yellow (uncertain — only 1–2 models mention it), or red (disputed — models actively contradict each other).
Confidence at a Glance
Verified text appears directly in the response with colored background highlights. Click any highlighted claim for full details.
