How to give ChatGPT or Claude access to your documents

Documents are scattered by nature. Proposals are in Word, project briefs are Google Docs, the team wiki is in Notion, and a folder of Markdown files holds technical notes. When you ask ChatGPT or Claude to draft a new proposal in the style of the last three, or to check a plan against a policy, the first job is collecting the right documents from four different apps.

This guide covers the ways people usually give an AI tool access to documents, and how to bring your documents into a single Fabric library, connect it to ChatGPT or Claude, and have the AI search and read the documents it needs.

How people usually give ChatGPT or Claude their documents

Attaching files to a chat is the simplest method and works well for one or two documents. It becomes a chore when the right answer depends on finding the right file first, and the attached copy goes stale as soon as someone edits the original.

ChatGPT and Claude both offer ways to connect specific apps, such as Google Drive, so the model can look things up there. That works well for documents that live in that one app. Teams with documents split across Word files, Google Docs and Notion end up connecting each source separately, or leaving some out. How to connect Google Drive to ChatGPT or Claude covers the single-drive case.

Projects are the third approach: upload a reference set once and reuse it across chats. It fits documents that rarely change, such as a brand guide. Living documents need to be uploaded again whenever they change.

Step 1: Bring your documents into Fabric

Drag files into the Fabric web or desktop app, paste them, or click Upload a file. Fabric handles DOCX, TXT, Markdown, HTML and JSON, along with PDFs and slides, and uploads large numbers of files at once.

For a team, the desktop app mounts Fabric as a virtual drive on Mac, Windows and Linux, so people can save documents into a shared Fabric folder from Word or any editor and work from it like a shared drive. Files take no space on the computer and stream when opened.

Google Docs and Notion pages come in through connections. Google Drive syncs in both directions, so documents stay in Drive and in Fabric at once. Connections need a paid plan. You can also write new documents directly in Fabric’s notes and docs editor.

Step 2: Let Fabric index the contents

Fabric reads the text inside each document, creates embeddings so search can match by meaning, writes a summary, and extracts the topics it covers. Try searching for a clause or idea you know is in a document. Search covers the full text, and putting words in quotes gives an exact match for policy names or contract terms.

Folders and tags are optional, but a folder per client or project helps when you later want an AI tool to work from a specific set.

When a document is revised, update it in Fabric. Files synced from Google Drive update on their own, so the next question reads the current version without another upload.

Step 3: Connect Fabric to ChatGPT, Claude or a coding tool

The Fabric MCP server gives the AI tool access. The URL is https://mcp.api.fabric.so/mcp, and sign-in is OAuth with no API key.

In Claude, add Fabric from Claude’s official connector directory. To do it by hand in Claude Desktop, go to Settings, then Connectors, add a custom connector, and enter a name and the URL before signing in.

In ChatGPT, open Settings, go to Connectors, choose Add Connector, enter the URL and a name, and save. In a new conversation, click More, then Add Connectors, then choose Fabric and sign in.

Developers who keep specs and design docs in Fabric can connect the same server in their tools. In Claude Code, run claude mcp add fabric --transport http https://mcp.api.fabric.so/mcp, restart, and sign in through the browser on first use. In Codex, run codex mcp add fabric --url https://mcp.api.fabric.so/mcp. In VS Code with Copilot, add a server named fabric to .vscode/mcp.json or your user settings with type http and the URL.

Step 4: Put the AI to work on your documents

With Fabric connected, ChatGPT or Claude can search your library and read file contents, including files from connected apps like Google Drive. Ask questions that need the right document first: “Find our remote work policy in Fabric and check whether this travel plan follows it,” or “Read the last three proposals in my Fabric folder Proposals and draft an outline for a new one in the same structure.”

Long documents are where this helps most. Instead of pasting a 40-page handbook into a chat section by section, ask the AI tool to find the handbook in Fabric and answer from it, then ask a follow-up about a different policy without attaching anything new.

The AI tool can also create and edit notes in Fabric, so a first draft can go straight into your library for the team to review. Items it creates count against your Fabric storage and AI usage.

Frequently asked questions

Can ChatGPT read Word documents stored in Fabric?

Yes. Once Fabric is connected as a connector, ChatGPT can search your Fabric library and read file contents, including DOCX files.

Can Claude read my Google Docs through Fabric?

Yes, if Google Drive is connected to Fabric. The MCP server lets Claude read files from connected apps like Google Drive. Connections need a paid plan.

Can the AI edit my documents?

Through the MCP server, the AI tool can create and edit notes in Fabric. Inside Fabric, the built-in AI assistant can edit documents directly, with accept or reject on each change.

Which document formats does Fabric support?

DOCX, TXT, Markdown, HTML and JSON, plus PDFs, PPT and PPTX slides, and EPUB ebooks. Google Docs and Notion come in through connections.

Do I need an API key for the Fabric MCP server?

No. Sign-in uses OAuth, and other MCP clients that support remote HTTP servers discover it automatically.

How do I connect Fabric to Cursor?

Open Cursor Settings, go to MCP, choose Add new MCP Server, set the type to URL, and enter https://mcp.api.fabric.so/mcp.

Can my team share one document library with their AI tools?

Yes. Keep documents in a shared Fabric space or drive, and each person connects their own AI tool to Fabric. See pricing for teams for team plans.

What if the connector won’t sign in?

Remove the Fabric server from the AI tool and add it again.

Can ChatGPT read Markdown files stored in Fabric?

Yes. Markdown is one of the document formats Fabric stores, and a connected AI tool can read its contents like any other file.
