Collaborative text editor for teams writing and organizing knowledge together, built by the French and German public administrations.
Docs is a collaborative editor for teams whose notes should turn into shared knowledge. It comes out of a joint initiative between the French and German governments, through DINUM and ZenDiS, and is aimed at public organizations, companies and open communities that want to keep their documents on their own infrastructure.
The editor is built on ProseMirror and BlockNote, with Yjs and HocusPocus handling live collaboration, a Django Rest Framework backend and a Next.js front end. Writing is rich text and Markdown with slash commands, a block system and offline editing.
Day to day, the workspace covers more than typing.
- Live collaboration: cursors and presence, comments, sharing and granular access control per document.
- Knowledge structure: subpages and hierarchy, with search across the content inside them.
- Presentations: a delimiter turns any document into slides, with full screen, keyboard navigation, a share link and PDF export.
- Import and export: bring in docx and Markdown, send out docx, odt and pdf.
- Optional AI: model and gateway agnostic rewriting, summarising and translating, configured with an API key and an address.
An interoperability API lets other services push content in, and the project's own video tool uses it to file meeting transcripts. Self-hosting runs on Kubernetes or Docker Compose, with community recipes for Nix and YunoHost. The license is MIT, though PDF export pulls in GPL packages, so a build flag produces an image without them.
End-to-end encrypted document editor for teams that want Google Docs style collaboration without handing the contents to a hosted service.
Collaborative editing normally means handing the text to a server that can read it. dDocs is an end-to-end encrypted document editor where the contents stay readable only to the people holding the keys, built as a privacy focused alternative to Google Docs.
The project ships as a React package called DdocEditor that drops into an application already using Tailwind CSS. Peer dependencies for drag and drop, the Fileverse UI and crypto libraries, viem and animation stay outside the bundle, so an app that already has them does not ship two copies. Props control preview mode, initial content, change callbacks and collaboration.
The editor covers what a shared document is expected to do.
- Collaboration modes: real-time and asynchronous editing, with suggestion mode for tracked changes and commenting.
- Authoring formats: Markdown and LaTeX input plus MermaidJS diagrams inside the document.
- Import and export: documents move in and out as docx, md, pdf and html among other formats.
- Offline work: older documents stay open and editable with no connection, then sync across desktop and mobile.
- Zero-knowledge access: proofs gate private access permissions and drive social recovery of an account or its files.
- Agent API: an opt-in encrypted programmable interface aimed at automated clients.
Version history, dark mode and color themes round out the editor, and the web app is optimized for mobile and installable as a progressive web app. It suits a team that wants document collaboration inside its own product rather than a hosted office suite.
