SuperDoc

The document engine for AI agents and teams that need real DOCX and PDF deliverables.
Renders, edits, and automates .docx files in the browser, headless on the server, and through stateless APIs.
Tracked changes, comments, collaboration, signatures, and structured document workflows — built on real OOXML.

Why SuperDoc

Use SuperDoc when your workflow needs a real document artifact — one that humans can review, redline, comment on, approve, sign, export, and send.

Best for:

Legal redlines and contract review
Due diligence memos and reports
Proposal and response packs
Template-driven document automation
Human-in-the-loop agent workflows

Not for:

Markdown publishing or blogs
Note-taking apps
Generic text generation
"HTML now, export DOCX later" hacks

Features

Real DOCX, not rich text — Built on OOXML. Real pagination, section breaks, headers/footers, comments, and tracked changes. Not a contenteditable wrapper with export bolted on.
Built for agents — MCP server, SDKs, CLI, and headless workflows. Agents read, edit, comment, and save real documents using structured operations.
Human review built in — Tracked changes, comments, approvals, and collaboration in the same workflow agents use.
Stateless API — Convert, annotate, sign, and verify documents without persistence. Process and return.
Real-time collaboration — Yjs-based CRDT for multiplayer editing with shared state.
Self-hosted — Runs entirely in the browser. Your documents never leave your servers.
Any framework — React, Vue, Angular, Svelte, vanilla JS. One component, zero lock-in.
Dual licensed — AGPLv3 for community use. Commercial license for proprietary deployments.

Quick Start

npm install superdoc

React

npm install @superdoc-dev/react

import { SuperDocEditor } from '@superdoc-dev/react';
import '@superdoc-dev/react/style.css';

function App() {
  return (
    <SuperDocEditor
      document={file}
      documentMode="editing"
      onReady={() => console.log('Ready!')}
    />
  );
}

See the @superdoc-dev/react README for full React documentation.

Vanilla JavaScript

import 'superdoc/style.css';
import { SuperDoc } from 'superdoc';

const superdoc = new SuperDoc({
  selector: '#superdoc',
  toolbar: '#superdoc-toolbar',
  document: '/sample.docx',
  documentMode: 'editing',
});

For AI Agents

If your agent needs to produce a real Word or PDF artifact, start here.

MCP server

npx @superdoc-dev/create              # generates AGENTS.md for your framework
claude mcp add superdoc -- npx @superdoc-dev/mcp   # connect agent to DOCX files

Why agents use SuperDoc

Structured document operations — not brittle file mutation or string replacement
Same document model across editor, SDK, and automation
Tracked changes and comments as first-class outputs
Reviewable artifacts humans already understand and trust
