Cortex

Memory for AI coding agents that you can hold accountable.
  Keep decisions, fixes and project context between sessions, and inspect what was retrieved.
  Runs locally by default. No account, no API key, no server to manage.

Sovereign is what it is today. Everything runs on your machine: a local SQLite file by
default, or PostgreSQL + pgvector if you prefer. No LLM in the retrieval loop, and nothing
leaves localhost unless you configure an integration that does. Your project's memory is a
file you own and can delete.

Claude Code and Codex share Cortex memory. Both native plugins provide the same
memory tools and 11 lifecycle hook modules for automatic capture, recall and project
context. Use either agent on a project and keep its memory when you switch.
Verified with real Claude and Codex sessions on macOS.
The same stdio MCP server also supplies memory tools to Claude Desktop, Claude Cowork
and other local MCP hosts.

Eco-responsible is what we are aiming at. Work that never reaches a datacenter is work
nobody has to power, and an agent that finds the right context first time re-reads fewer
files. We hold that intent to the
Green Software Foundation's SCI method, and we
publish no CO₂ or energy figure, because we have not measured one.
What we do and do not claim ↓
36 implemented, inspectable neuroscience-inspired mechanisms · 57 memory tools · 11 lifecycle hooks · a self-curating per-project wiki — all local, all open-source, MIT.
The committed ablations do not establish that these 36 mechanisms improve retrieval
collectively or individually. Published neuroscience references explain their design;
retrieval benefits require measurements in Cortex. See Verification.
