Persistent Zettelkasten Storage With Metadata Indexing

via “note tagging and organization”

Manage and explore atomic notes using the Zettelkasten methodology through an MCP-compatible interface. Create, link, search, and synthesize notes with AI assistance to build a rich, interconnected knowledge graph. Enhance your knowledge workflow with bidirectional linking, tagging, and markdown-bas

Unique: Implements a flexible tagging system that supports nested tags, enabling users to create a structured organization of their notes.

vs others: More versatile than flat tagging systems, allowing for complex categorization that reflects user workflows.

Hey HN! Over the weekend (leaning heavily on Opus 4.5) I wrote Jargon - an AI-managed zettelkasten that reads articles, papers, and YouTube videos, extracts the key ideas, and automatically links related concepts together.Demo video: https://youtu.be/W7ejMqZ6EUQRepo: https:/&#x2F

Unique: Combines structured storage with full-text indexing and relationship metadata, enabling both efficient retrieval and graph-based exploration of the knowledge base

vs others: More queryable than plain file storage (Obsidian vault) and more portable than proprietary databases (Roam Research), with standard export formats
