Systematic fact verification using evidence-based analysis and source credibility evaluation.

• Identifies claims, determines required evidence, and evaluates sources across a credibility hierarchy from peer-reviewed studies to social media
• Applies a six-tier rating scale (TRUE, MOSTLY TRUE, MIXED, MOSTLY FALSE, FALSE, UNVERIFIABLE) with clear reasoning and confidence levels
• Detects common manipulation patterns including statistical cherry-picking, context removal, false equivalences, and logical fallacies
• Provides structured output with verdict, analysis, evidence, context, and corrected information when claims are inaccurate
