CollabWrite: Real-time Collaborative Text Editor ## Abstract This document outlines the core features and architecture of CollabWrite, a real-time collaborative text editor with integrated git-style version control. Key features include concurrent editing, committing changes with commit messages, viewing document version history, and inviting other users to collaborate. ## Core Features 1. **Concurrent Editing**: Leveraging CRDTs (Conflict-free Replicated Data Types) to ensure seamless, real-time text synchronization between multiple users without a central server for conflict resolution. 2. **Version Control**: - **Committing**: Users can create a snapshot of the document's current state, similar to a 'git commit'. Each commit is associated with a descriptive message. - **History**: A visual timeline allows users to browse through past versions, view diffs, and revert changes if necessary. 3. **Collaboration**: - **User Invitations**: A unique, shareable link can be generated to invite collaborators to a document. - **Presence**: Real-time cursors and selection highlighting show what other users are doing in the document. ## Technology Stack - **Frontend**: Next.js, React, Tailwind CSS - **Real-time Engine**: To be determined (e.g., Liveblocks, PartyKit, or a custom WebSocket solution) - **AI Integration**: Genkit for AI-powered features like commit message generation.
