Open-source fact-checker for AI agents enforces source verification

IndividualChannel546 · reddit · 2026-09-01

Addressing the issue where AI models often claim 95% confidence regardless of accuracy, the author released an open-source fact-checker for agents. It fetches real-time sources instead of relying on model memory, returning a truth score and a confidence score alongside sources. Crucially, it supports verifying internal documents against their citations (e.g., policies, schemas), successfully identifying planted errors in demos. MIT licensed, it runs locally in browsers or as an MCP tool.
