On February 17th, SCAICH, the first product in the AI direction of the SciHub community, began public testing. It is reported that SCAICH is an AI-based research paper search engine that can search 140 million papers in Sci-Hub and open journals. SCAICH uses SCAI, a self-developed scientific AI agents framework, jointly developed by the SciHub community and WTF Academy. The community said that the project will be open-sourced in the future.
