Separate assertions
Break down dates, numbers, comparisons, causes, and qualifications.
QUALITY CONTROL / AI-GENERATED CONTENT
AI can sound right.
Check the claims.
ProofGate takes a draft apart, checks each factual statement against source material, and shows you what the evidence does—and doesn't—establish.

Checking model availability…
Free beta. Results show support within supplied sources only, not independently established truth. Errors and omissions remain possible. No account required; usage limits apply. Default routing favors eligible lower-cost models.
SOURCE-BASED ANALYSIS
Claim findings
Review source quality and material conclusions yourself. The beta does not certify that statements are true.
WHY IT MATTERS
One sentence can contain three different factual claims.
A company may have reported $15 million in revenue. That does not establish it grew by 30%, or that it leads its industry. ProofGate checks each assertion separately so that evidence for one claim cannot automatically approve the others.
Require quotations
Check that cited passages actually appear in the supplied source.
Hold unsupported claims
Identify contradictions and gaps rather than guessing.
QUESTIONS / ANSWERED
What ProofGate actually does
Is this an AI hallucination detector?
It detects some unsupported or contradictory claims relative to your evidence. It cannot identify every hallucination or validate a source independently.
What is an atomic claim?
A single statement that can be checked independently. A sentence with a revenue figure, a growth percentage, and a market ranking contains at least three claims.
Can I check PDF and Word documents?
For now, paste their text. The beta also imports TXT, Markdown, CSV and JSON text files locally in your browser.
Does ProofGate replace an editor or fact-checker?
No. It is a review assistant. Important financial, legal, medical, and regulatory decisions require qualified human checking.
