Cortex

Cognitive knowledge system with formal ontology, reasoning, and intelligence serving.

Cortex captures knowledge objects (decisions, lessons, fixes, sessions, research, ideas), classifies them with an OWL-RL ontology, discovers relationships, reasons over the graph, and serves intelligence through hybrid retrieval.

Install

pip install abbacus-cortex[embeddings]
cortex setup

The setup wizard configures everything: LLM provider, embeddings, dashboard password, background services, and Claude Code registration.

Other install methods

Lightweight (no PyTorch — wizard offers to install embeddings):

pip install abbacus-cortex
cortex setup

Homebrew:

brew install abbacusgroup/cortex/abbacus-cortex
cortex setup

From source:

git clone https://github.com/abbacusgroup/Cortex.git && cd Cortex
uv sync --extra embeddings
cortex setup

Docker:

docker compose up -d

For non-interactive installs (CI, scripts): cortex setup --auto uses environment variables.

Quick Start

cortex capture "Fix: Neo4j pool exhaustion" --type fix --content "Root cause was..."
cortex search "Neo4j"
cortex list
cortex context "Neo4j"
cortex dashboard                    # web UI at http://localhost:1315

Configuration

cortex setup writes configuration to ~/.cortex/.env. You can also edit it directly:

CORTEX_LLM_PROVIDER=anthropic
CORTEX_LLM_MODEL=claude-sonnet-4-20250514
CORTEX_LLM_API_KEY=sk-...
CORTEX_EMBEDDING_MODEL=all-mpnet-base-v2

Cortex loads .env from these locations in priority order: environment variables (highest), .env in the current working directory, then ~/.cortex/.env. The recommended location is ~/.cortex/.env for persistent configuration.

See .env.example for all options.
