The Revise Editor SDK is a browser-only React component that embeds a word processor in your application. Your application keeps its own shell, authentication, storage, and users. You give the SDK a document (.docx, .odt, .rtf, Markdown, plain text, or HTML) and get a .docx back. The component:
  • parses the file with Revise’s converters, keeping comments and tracked changes on the DOCX path;
  • opens a Yjs-backed editing session. Every document is a CRDT, so real-time collaboration over your own transport needs no extra setup;
  • renders the document on canvas with pagination, with the built-in ribbon or your own toolbar;
  • keeps comments and tracked changes through the round trip;
  • exposes Revise’s document-local JSON-schema tools, so the model you already run can read and edit the document;
  • exports to .docx.
Server-side work is revise, the MIT CLI and TypeScript library built on the same engine and released at the same version. Your server can join the same collaborative documents: seed rooms before anyone opens them, edit live documents headlessly, propose tracked changes for a user to review in the browser, and export to Word. All of this works on a host-owned Y.Doc, with no React mount and no model. Browser and server share one tool contract: the same tools, schemas, and { ok, value | error } results. See collaboration and the revise library.

​
What it does not include

The SDK does not provide accounts, authentication, document storage, collaboration servers, tenancy, billing, or an application shell. It is a component, not a platform. Nothing leaves the browser unless you connect an agent.
For multi-user editing, pass a Yjs provider (Hocuspocus, y-websocket, or your own). The document then shows remote carets and presence. The SDK never opens a connection or stores anything. There is no document locking, and roles are enforced on the client, not the server. See collaboration and roles.
Install it with npm i @reviseio/editor. The SDK is closed-source and free for evaluation, personal projects, and education. Production use by businesses, nonprofits, and government requires a license.

​
Two API surfaces

The SDK has one API for your application and one for your agent.

Your application

Component props, callbacks, and the typed controllers on ReviseEditorHandle. Subscriptions, focus management, File and Blob objects, custom toolbars and panels. See the handle reference.

Your agent

JSON-schema tools with serializable inputs and outputs. They operate on semantic document state, not UI geometry, and run without React state or browser focus. See agent tools.
Some capabilities exist on both surfaces, such as selection, with different shapes for each. Interactive state such as review navigation and the comment panel is host-only. Agents get semantic mutation tools instead.
