Description

ChaCha was a human-guided search engine that provided free, real-time answers to any question. Founded in 2006, the company utilized a unique model where users could ask questions via a web interface or mobile app, and receive answers from a network of freelance guides. These guides used a combination of search tools and their own knowledge to provide accurate and timely responses. ChaCha aimed to offer a more personalized search experience compared to traditional search engines. However, the company ceased operations in 2016.
