It enables multiple users to brainstorm and create content together on a shared virtual canvas using freehand sketching, geometric shapes, and text labels. The platform focuses on private workspace management, allowing the creation of restricted boards via unique URLs and token-based access control to manage editing permissions. It integrates real-time state synchronization for drawing updates and a built-in chat system for text communication between collaborators. The workspace includes tools for canvas navigation, stroke customization, and data persistence across sessions. Users can export their visual work as scalable vector graphics or save workspace states to local files. The system includes administrative infrastructure for server performance monitoring, request rate limiting to prevent abuse, and content moderation tools to ban users. The interface supports global use through a multi-language localization system. ## Tags ### Business & Productivity Software - [Real-time Collaboration](https://awesome-repositories.com/f/business-productivity-software/team-collaboration-events/collaboration-communication-tools/collaboration-tools/real-time-collaboration.md) — Implements a shared virtual canvas for simultaneous multi-user sketching and real-time visual brainstorming. - [Private Board Generation](https://awesome-repositories.com/f/business-productivity-software/team-collaboration-events/collaboration-communication-tools/collaboration-tools/workspace-collaboration/workspace-access-controls/private-board-generation.md) — Allows the creation of restricted boards via unique URLs to ensure access is limited to invited users.
