cortex vs agent-memory

cortex: Cortex is a private, free, and local memory engine for personal AI agents, built with Rust. It provides multi-tier, self-evolving long-term memory that persists across sessions and devices, offering sub-millisecond performance and end-to-end encrypted cloud synchronization.; agent-memory: Agent-memory offers local, Git-native project memory for AI coding agents, leveraging Markdown as the single source of truth for durable, human-reviewable, and secret-safe knowledge. It facilitates structured memory updates and seamless integration with various agent runtimes, operating entirely locally without external cloud or vector database dependencies.

Features

cortex logocortex
01Private by Default: Memories reside in a local SQLite file, ensuring zero telemetry and data privacy.
02Real, Multi-Tier Memory: Features 4 memory tiers (Working, Episodic, Semantic, Procedural), multi-signal retrieval, Bayesian beliefs, and a cross-channel people graph.
03Sub-millisecond Performance: Achieves 156µs ingest and 568µs search speeds, significantly faster than cloud memory APIs.
04Cross-Device End-to-End Encrypted Sync: Optionally syncs memories across devices through your own cloud storage (iCloud, Google Drive, etc.) with AES-256-GCM encryption.
05Drop-in Integration: Serves as an MCP server for Claude, offers Python bindings, and integrates with frameworks like LangGraph, DeerFlow, and OpenClaw.

01Git-native, Markdown-based memory with version control.
02Human review gate for durable changes via diffs.
03Automated scanning and rejection of secrets/PII on write.
04Fully local operation without cloud or vector database dependencies.
05Verifiable Task Protocol (VTP-1) for cryptographic task lifecycle.
06Federated memory for referencing shared, read-only 'landscape' stores.
