What is Fast.io?

Fast.io is an agent-native content management platform designed for modern teams that collaborate with AI agents. Built by Fastio, it solves the problem of managing files and workflows across human team members and AI agents in a single, secure workspace. Core capabilities include real-time collaborative editing, frame-accurate comments on documents, video, and audio, permissioned sharing with guest access controls, and AI-powered metadata extraction from unstructured content. It integrates with major AI agents like Claude, ChatGPT, Gemini, and Cursor via MCP, and also offers its own built-in AI teammate, Ripley. The platform provides scoped tokens, full audit logs, and enterprise-grade security with AES-256 encryption and TLS 1.3. Fast.io fits workflows for teams that need to hand off work between humans and agents, manage client portals, and extract structured data from files at scale. It is trusted by teams at various organizations and offers unlimited users with free MCP, CLI, and API access.
