About cdeust/Cortex

Cortex provides persistent memory for Claude Code using PostgreSQL and pgvector. It stores and retrieves information across sessions based on 26 biological mechanisms with ablation evidence from 41 neuroscience papers, achieving 98.4% R@10 on LongMemEval and 94.2% on LoCoMo.

Best for

Developers who need reliable long-term memory for Claude Code in complex, multi-session projects.

Use cases

Maintaining conversation context across long Claude Code sessions
Retrieving relevant prior knowledge during agentic coding tasks
Building memory-augmented coding assistants with verifiable retrieval

Notes

41 stars on GitHub. Last updated 2026-06-01.

Pros

High retrieval accuracy validated on multiple benchmarks (LongMemEval, LoCoMo, BEAM-10M)
Neuroscience-inspired design with per-mechanism ablation evidence for transparency
Uses widely compatible PostgreSQL with pgvector extension

Cons

Requires managing a PostgreSQL instance with pgvector
Tied specifically to Claude Code, limiting reuse with other LLMs
Setup and tuning may be non-trivial for casual users
