cortex vs telemem

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.; telemem: TeleMem is an advanced agent memory management layer, offering high-performance, character-aware, long-term, and multimodal memory capabilities for conversational AI. It significantly improves memory accuracy and speed, supporting complex scenarios like multi-turn dialogues and video content understanding.

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.
telemem logotelemem
01Automatic, isolated per-character memory profiles for multi-persona agents.
02Full multimodal memory pipeline for video understanding and ReAct-style video QA.
03LLM-based semantic clustering and deduplication for improved memory consistency.
04High-performance, efficient asynchronous writing with batch flush.
05Fully local operation by default with support for various LLM providers.
