 ## What is Sico?
 
-Sico — Symbiotic Intelligence for CO-evolution — is an open-source platform for building, managing, and evolving **Digital Workers**: structured AI labor units that co-evolve with human operators through real production work, particularly in BPO (Business Process Outsourcing) scenarios.
