Free plan: 3 verifications/month / No credit card required

How it works

Highlight any part of a ChatGPT response you want to verify.

Click the 🔍 button or use the right-click context menu.

See each claim's risk level and reasoning in the side panel.

🎯

Extracts individual claims and assigns risk levels to each. Not just "right or wrong" — you see what to verify first.

⚡

Works directly on the ChatGPT page. No need to switch tabs. Results appear in seconds.

🔒

Only the selected text is sent for analysis. We never collect or store your conversation history.

🤖

Uses Anthropic's Claude for analysis. Cross-checking with a different AI reduces single-model bias.
