Cognee is the open-source AI memory platform for agents.
Cognee is an open source memory platform for AI agents. It gives agents persistent memory across sessions by combining graph, vector and relational retrieval, so an agent can recall what it did last week, connect facts that live in different systems, and follow domain rules it was never trained on. Developers install i...
Give your AI a real, persistent memory.
AI Memory Vault is a free memory system for Claude Code published by the creator behind jaredrhod, who shares practical AI setups for business owners. The vault is a folder of plain text files on your own computer: Claude Code reads it at the start of every conversation and writes to it as you work, so the assistant ke...
Memory for AI agents that learns what is wrong and stops repeating it.
Hippo is a long term memory layer for AI coding agents. It stores lessons from your sessions locally and surfaces them again in later ones, so an agent does not repeat the same deployment mistake or forget a project convention such as which package manager a repository uses. The design borrows from how human memory be...
Memory library for building stateful agents
Honcho is an open source memory library, with an accompanying managed service, for building stateful AI agents. It gives an agent persistent memory about users and other entities across sessions, tools and models, and it reasons over stored data to draw out insights instead of only retrieving text chunks. It works with...
Local persistent memory store for LLM applications including claude desktop, github copilot, codex, antigravity, etc.
OpenMemory is an open source long term memory system for AI agents and assistants. Rather than storing flat embeddings, it encodes conversations into five sectors: factual, emotional, temporal, relational and behavioral. Memories decay along configurable curves with per sector slopes and floors, and reinforcement pulse...
Shared memory for AI agents
PLUR is an open standard and toolkit for persistent AI agent memory. It gives coding agents one shared memory that carries across tools, models and sessions, so a correction made in Claude Code is already known to Cursor, and a pattern learned by a subagent is available to an orchestrator on its next run. Memory is st...
