khoj and SurfSense
Both are self-hostable AI tools for knowledge management, but Khoj AI is a standalone personal AI second brain and research assistant, whereas SurfSense is an open-source alternative to NotebookLM explicitly designed for teams, suggesting they are competitors with different target users (individuals vs. teams).
