Credibility Analyzer is a browser extension and mobile app that fact-checks selected text using LLMs (Gemini, Claude, GPT) with optional on-device Gemini Nano. It provides credibility scores, claim-by-claim verdicts, and publisher bias ratings, but lacks open-source code and relies on paid API keys.

Target audience: general users, researchers, journalists
