Cortex — The Knowledge Engine
A graph-aware knowledge engine that indexes your vault, learns from how you use it, and gives your AI the memory it was missing. The power of knowledge.
Notes, emails, and decisions become a graph your AI can walk. Ask once — Cortex lights the path and answers with the source.
Cortex Engine turns your knowledge base into a graph that AI can walk, search, and remember. No cloud. No embeddings. No API calls. A single binary that runs on your machine and gives your AI the tools to understand your knowledge — not just retrieve it.
Inside the Araptus Engine, Cortex is the memory layer — insights from Signal land here for long-term recall.
Three Layers
The foundational architecture. Each layer builds on the one below it.
Graph
92Indexes every note, link, embed, and tag. Walks the link graph with pruning heuristics.
Memory
85Neural synapses learn which notes matter together. Semantic memories persist across sessions.
Intelligence
78Discovers hidden connections. Suggests missing links. Understands your topic taxonomy.
How It Works
Four phases. Each one feeds the next.
Index
Point it at your knowledge base. Cortex Engine parses every file — tags, links, embeds, relationships. Builds a full link graph in memory.
Walk
Your AI uses graph tools to explore. Smart traversal follows the strongest connections, prunes noise, and delivers exactly the context that matters.
Learn
Every walk strengthens connections between co-accessed notes. Every recall makes a memory stronger. Every session teaches the persona what matters to you.
Remember
Facts, decisions, insights stored as files you can read and edit. Memories decay naturally over time — what you don't use fades. What you revisit gets stronger.
Constraints
What Cortex Engine will never require. These are load-bearing walls.
No Cloud
No Database
No API Keys
No Embeddings
No Runtime
A single binary under 5MB. Your data never leaves your machine.
Want Cortex Engine for Your Team?
Cortex Engine ships free with the Araptus Client Ecosystem. Standalone licenses available for teams that want the graph engine without the full stack.
