FactSnap – An AI browser extension developed by Studio NAND

What is FactSnap?

FactSnap is an AI-powered browser extension developed by Studio NAND that helps users quickly verify the authenticity of information on web pages. By integrating multiple AI models and search engines, it performs real-time fact-checking on selected text while users browse. Simply highlight any text and click the FactSnap icon to receive an initial judgment within one second, indicating whether the information is accurate, suspicious, or false. FactSnap then retrieves relevant data for deeper verification, generating summaries along with source citations.

Using a “three-stage” verification method combined with LLaMA 3.3 and GPT-4o-mini models, FactSnap helps users avoid misleading content—ideal for researchers, journalists, and everyday users who want to fact-check on the fly.
