What SAGE3 is

SAGE3 is an open-source collaborative workspace for people working together and with AI. Shared boards distribute uploaded content to connected devices, including laptops and display walls, and support wireless sharing of multiple computer screens. The infinite canvas accepts sticky notes, pictures, videos, PDFs, Google Docs, maps, and web pages, with voting tools for group work. Its chat interface supports collaboration with ChatGPT or Llama, including document summaries and comparisons. SAGECells are spatial two-dimensional code cells where multiple developers can work simultaneously using the same or different Python kernels. Teams can create dashboards by dragging existing web-portal URLs onto boards and extend the workspace with native applications or plugins. Users may connect to hosted hubs or host a hub on their own server. Platforms include Linux, macOS, self-hosted, web, and Windows. The no-fee license covers academic, research, and internal business use; commercial use requires another license.

Who it suits

SAGE3 suits academic, research, and internal business teams collaborating across shared canvases, screens, documents, and code. Organizations wanting commercial use must obtain a separate commercial license.
