Claude's built-in accuracy guardrails vs. Verol's independent verification
Claude is designed to be cautious. But a careful tone isn't the same as verified facts — and an independent check catches what hedging can't.
Claude uses Constitutional AI training and reinforcement learning from human feedback to encourage cautious, hedged responses. It often signals uncertainty and avoids some categories of confident error.
Verol runs alongside Claude in your browser, extracting factual claims from its responses and independently verifying them against primary sources — regardless of how confident or uncertain Claude's phrasing sounds.
Claude's safety training teaches it when to sound uncertain. Verol independently checks whether the underlying claims are actually accurate — regardless of tone.

Common questions
Does Claude's extended thinking mode prevent hallucinations?
Claude's extended thinking mode improves performance on reasoning and math tasks by making the reasoning process more transparent. However, it doesn't provide external grounding — the model can reason carefully through incorrect premises and reach a confident but wrong conclusion.
Why does Claude still produce inaccurate outputs despite its safety training?
Claude's training encourages it to hedge on uncertain topics. However, when the model has high confidence in a pattern from its training data — even if that pattern is incorrect — it will present the information without qualification. Safety training and factual accuracy are different dimensions.
Does Verol work inside Claude.ai?
Yes. Verol is a Chrome extension that activates on supported AI chat interfaces including Claude.ai, automatically detecting and verifying factual claims in responses.
