Thought Keeper
A markdown-based knowledge management system that combines the simplicity of plain text with powerful organization features. Thought Keeper uses a Zettelkasten-inspired approach with bidirectional linking, tags, and hierarchical organization.
The system supports mathematical notation, code blocks, diagrams, and embedded media while maintaining clean markdown compatibility. It includes full-text search, backlink discovery, and graph visualization for exploring knowledge networks.
Thought Keeper manages references and citations for academic and research use cases. The architecture prioritizes longevity with open formats, export capabilities, and version history for all notes.
