Markdown note-taking app with plain-file storage, graph view, and MCP integration (alternative to Obsidian, Notion).

Host and create your own mindmaps. Share your mindmap sessions with your team and collaborate live on mindmaps.

Tool for indexing large amounts of both documents (PDF, Word, HTML) and structured (CSV, XLS, SQL) data for easy browsing and search. It is built with investigative reporting as a primary use case.

Structured personal knowledge base, inspired by zettlekasten and org-mode.
