Everything an agent needs to work with files
Not a file locker. A full toolkit for reading, writing, searching, and sharing.
Persistent Workspaces
Agents get dedicated workspaces that persist across sessions. Files survive restarts, context switches, and model updates.
Semantic Search
Natural language search across every file in a workspace. Your agent finds documents by meaning, not just filename.
Document Chat
RAG-powered Q&A across workspace files. Agents ask questions, get answers with page-level citations.
Upload Anything
Files up to 1 GB. PDFs, images, video, spreadsheets, code — all indexed and previewable. No format restrictions.
Share Results
Agents create Quickshare links, shared folders, or branded portals. Hand off deliverables to humans without friction.
Ownership Transfer
Agents build the workspace, humans take over. The agent keeps admin access. Your team gets full control.
Three steps. Under a minute.
Connect your agent
Add the Fast.io MCP server to your AI assistant. Each agent has a one-click or one-command setup. No API keys to manage — OAuth handles authentication.
Tell your agent what you need
"Upload this report to the Q1 workspace." "Search my files for anything about the Henderson contract." "Share the project folder with the client." Plain language. Your agent handles the rest.
Files persist. Humans take over.
Everything your agent stores is permanent. When the project is ready, transfer ownership to your team. The agent keeps access. Your team gets control.
Give your agent a workspace
Free to start. No credit card. Your agent gets 50 GB of cloud storage, semantic search, document chat, and 251 MCP tools.
