Open Source Word Processor in Your Browser
Client-side .docx editor with React, Vue, real-time collab, and AI Agent SDK for LLM-driven document automation.
Today, I’d like to introduce a newly released 1.0 open-source project — docx-editor: a Word document editor that runs entirely in the browser. It supports both React and Vue, runs purely on the client side with no backend required, and keeps all documents inside the user’s browser. Even more exciting is its built-in AI Agent SDK, which allows large language models to directly manipulate the document — adding comments, enabling track changes, performing automatic review, and applying edits in real time as the model streams its output.
docx-editor is a WYSIWYG .docx editor component library open-sourced by the eigenpal team. Its positioning is crystal clear: DOCX in, DOCX out. Load a Word document as an ArrayBuffer, edit it in the browser, and save it back as a standard OOXML file. Open it in Microsoft Word, and the formatting remains perfectly preserved.
It uses ProseMirror as the underlying editing engine and provides official React and Vue 3 adapters on top, sharing a single framework-agnostic core package. Key highlights include:
