HI all, First, thank you so much for your feedback and interest in my project PopUpFactCheck. When I first posted about this July 1, I did not expect the reception it would get and I am so thankful to y’all. Some updates. You asked for Firefox, and it is now a Firefox add-on. It has new features. For example, using the up and down arrows on Chrome (or Option (⌥) + ↑/↓ on Firefox) you can scroll back and forth of the factcheck bubbles already displayed. The fact checking on live videos has improved. And it now does batch reporting on an entire video. Once again, Claude Code was a major tool in my development, and the AI that is used for orchestration is OpenAI GPT 5.4 nano and mini. In addition, there is an extensive waterfall of sources including the TheNewsAPI, various government and public health and other APIs, social, and web search powered by DDGS and Serper.
