Full context
Your agent sees every file, folder, and version in the workspaces you allow. No manual uploads and no copy-paste to keep it current.

Not just smarter AI: real context + real actions
Most AI tools require you to copy, paste, and explain context. Fastio gives your agent direct access to your files plus the structured, machine-readable data around them, so it can act, not just answer.
Metadata
Fields extracted from your files, typed and searchable, so an agent can filter on what is inside a document rather than its name.
Summaries
An AI-generated summary for every document, so your agent can reason over the summary instead of loading the whole file.
APIs and MCP
A REST API and a hosted MCP server, with authenticated access to storage, search, AI chat, and shares from one consolidated toolset.
llms.txt
Machine-readable workspace descriptions following the llms.txt standard, so an agent can discover what a workspace holds on its own.
Take action
Upload and organize files, extract metadata, and hand finished work to people through a share. Your agent doesn't just read, it acts.
Workspace context
Your workspace, fully understood
Your agent doesn't just see file names. It understands content, structure, and relationships. Ask anything about your workspace and get instant, cited answers.
- Answers cite the files they were drawn from
- Ask across a whole workspace, not one file at a time
- Content, folder structure, and metadata all inform the answer
Your agent connects the dots across your data so you don't have to.

Data layer
Turn storage into an intelligent data layer
Fastio isn't just a place to put files. With intelligence enabled, every document is automatically indexed, summarized, and made queryable, turning your storage into a knowledge base your agent can reason over.
- Automatic RAG indexing on upload
- Semantic search across all documents
- AI-generated summaries and metadata extraction
- Scoped queries by folder, share, or workspace
Your files become a live knowledge graph your agent can query.
Client portals
Bring AI directly into client portals
Every client portal becomes smarter with AI inside. Instead of sending files and fielding questions, let your agent guide clients to the answers they need.
- Answer client questions about shared documents
- Explain reports, contracts, and data on demand
- Help clients navigate complex information without your team's time
Your clients get answers at midnight without waiting on your team.
Scoped access
Scoped intelligence in shared folders
Your agent understands structure and permissions. Whether working in a private workspace or a shared folder, it only sees what's in scope, keeping responses relevant and secure.
- Folder-level intelligence
- Permission-aware responses
- Instant folder summaries
The agent's view of your files stops exactly where the share does.
Document chat
Make every document interactive
Your files aren't static anymore. Your agent can open any document and start a conversation, summarizing, highlighting key risks, and answering detailed questions with context.
- Summarize long PDFs instantly
- Highlight key risks and insights
- Answer detailed questions with citations
- Compare documents side by side
Your documents become conversations, not just files.
Shared workspace
Work alongside your agent
Your agent works in the same workspace as your team. Every action it takes (uploads, file organization, metadata) is visible in the activity log. Review, adjust, and collaborate in real time.
- Full activity log of every agent action
- File locks so people and agents do not overwrite each other
- Comments and metadata on the files your team already sees
- Transfer ownership to a person when the work is ready
Nothing your agent does happens off the record.
Insights
Turn your data into insights
Your agent doesn't just read your data. It understands it. Get instant summaries, spot trends, and surface patterns across your entire workspace.
- Summaries across a folder or an entire workspace
- Trends and patterns pulled from many documents at once
- Extracted metadata turns unstructured files into comparable fields
Your reports stop being files to read and become data to ask.
