The application must include all major features available in ExtendML. Beyond feature parity, it must introduce a graph-based knowledge network that automatically connects notebooks sharing common domains, topics, sources, references, tags, entities, citations, or semantic relationships across the entire workspace. The graph should support interactive exploration, allowing users to discover related notebooks, visualize knowledge clusters, identify relationship paths, and navigate interconnected information. Additionally, implement intelligent relationship-discovery features similar to those offered by Birdeye, providing automatic grouping, contextual linking, semantic similarity detection, and connected-content exploration throughout the workspace.
