Files can move between people and AI agents
Browsers work for people and APIs work for software. Feichuan turns temporary material into deliverable links for people and agents.
Hand local material to AI
Upload PDFs, data files, archives, and other material, then give the Feichuan link to an AI agent.
Let an agent hand results back to you
An agent uploads its output through the API, receives a share link, and returns it directly to the recipient.
Hand material between agents
Agent A uploads an artifact and passes its share_url to Agent B without placing the large file in message context.
Cross-device file transfer and sharing
Feichuan moves files and text between computers, phones, and tablets. Visitor mode is designed for quick, temporary uploads, sharing, and receiving with pickup codes or links.
