Codex
The canonical knowledge repository for AI systems. Structured as Weaves, Looms, and Strands—designed for both human exploration and machine comprehension.
The Fabric Architecture
A four-tier hierarchy designed for both human understanding and machine traversal.
Fabric
The entire knowledge corpus as a living whole. Enables cross-weave synthesis by superintelligence.
Weave
Self-contained knowledge universes. Clean boundaries prevent knowledge pollution between domains.
Loom
Curated collections that define how strands connect and the order they should be consumed.
Strand
Atomic units of knowledge. Immutable, versioned, and richly typed with relationships.
One Model, Infinite Applications
Because everything is a Strand with relationships, OpenStrand can model any knowledge structure.

There's no fundamental difference between a "file" and a "folder"—both are Strands. A folder is just a Strand with children. This recursive model means you can nest infinitely, link anything to anything, and traverse your knowledge as both a tree AND a graph.
Built for the Future
Every feature designed with AI-first principles while remaining human-friendly.
Semantic Search
Client-side vector search with ONNX runtime. Find knowledge by meaning, not just keywords.
Dual Summaries
Extractive TF-IDF summaries plus optional AI-generated abstracts for every strand.
Local-First Cache
SQL.js powered caching keeps your browsing fast and works offline.
OpenStrand Schema
Typed YAML frontmatter with relationships, prerequisites, and rich metadata.
GraphQL + REST
Automatic fallback from GraphQL to REST. Works with or without a GitHub PAT.
Personal Notes & Tags
Add your own annotations and tags to any strand. Stored locally, never leaves your browser.
Pen & Paper Ready
Index card view for modeling knowledge without computers. Print, copy ASCII, organize physically.
Relationship Graph
Visual mini-graph showing prerequisites and references. Click to navigate between connected strands.
