Agent memory
Reviewed resources in Agent memory. 450 resources listed.
Hippo
hippo-memory.comA memory layer for AI coding agents that learns from outcomes rather than only storing everything: a memory marked wrong stops being recalled, a newer fact replaces an older one, and used memories get reinforced.
Semantix
semantix.ensureok.aiA cross-session memory kernel for coding agents that extracts reusable knowledge from finished sessions and injects it into new ones, either as a standalone coding agent or attached to an agent already in use.
CodeSeek
github.comA Rust-powered code-intelligence command-line tool for AI coding agents, building call graphs and hybrid semantic search indexes across seven languages, and exposing the results as native MCP tools for Claude Code and Codex.
Second Brain
thesecondbrain.devA self-hosted memory layer, deployed on a personal Cloudflare account, that stores notes once and makes them retrievable by meaning from Claude, ChatGPT, Cursor or any other MCP-compatible AI tool.
AutoMem
automem.aiA long-term memory service for AI assistants that combines a graph database of typed relationships with a vector index, so an assistant can recall the reasoning behind a decision rather than only similar past text.
Wax
github.comA single local file that gives Claude, Codex, Cursor and other agents a shared, searchable memory of text, photos and video on Apple Silicon, with no server, account or hosted database.
Axon
harshkedia.comA code-intelligence engine that indexes a codebase into a structural knowledge graph of dependencies, call chains and clusters, browsable in an interactive dashboard or queried by an AI agent through MCP tools.
Memorix
mem.rglens.comA local-first, shared project memory layer for coding agents, accessible through MCP, that keeps session summaries, git history and design decisions searchable across tools and sessions.
projectmem
projectmem.devA local coding-agent memory server that records issues, attempts, fixes and decisions per project, then warns the agent before it repeats an approach that already failed.
AI Coding Assistant Data Extraction
github.comA free, open-source tool that extracts a user's own local chat history from AI coding assistants such as Claude Code, Cursor, Windsurf, Aider and Cline into one normalized JSONL format.
NornicDB
github.comA graph database that combines Neo4j-compatible Bolt and Cypher access with vector search and MVCC-based historical reads, aimed at agent memory, graph-RAG and audit-friendly knowledge stores.
iai-personal-memory-engine
github.comA local MCP server that gives Claude and other MCP-compatible agents long-term memory by capturing every conversation turn verbatim and serving back relevant context automatically.
Memind
docs.openmemind.comA Java-native, self-evolving memory and context engine for AI agents that distills raw conversations, tool calls and documents into memory graphs and evolving insight trees, retrieved through REST, MCP and SDKs.
Octocode
octocode.aiAn agentic code-research platform, backed by a Rust engine, that lets an AI agent or developer search and read local code and GitHub repositories, pull requests and npm packages token-efficiently through one CLI or MCP toolset.
Voicetree
voicetree.ioA graph-based mindmap system, of markdown-file and terminal-agent nodes connected by edges, for building human-in-the-loop multi-agent coding systems that can recursively decompose tasks and share memory with a person.
Echo Agent
ojlab.comA self-hostable, long-running AI agent for personal or team automation, with four-layer cognitive memory, a forgetting curve and contradiction detection, plus LLM-based approval for high-risk actions such as running commands or files.
LocalRecall
github.comA local, no-GPU RESTful memory and knowledge-base layer for AI agents and chatbots, storing files and text in a vector database behind a web UI.
IM.codes
im.codesA shared context, memory and supervision layer that connects coding agents such as Claude Code, Codex and Gemini CLI to each other and to enrolled machines, which authorized agents can operate directly with scoped commands and remote desktop access.
CodeAlmanac
codealmanac.comCodeAlmanac is a living wiki for a codebase, written and kept current by AI coding agents, that captures the decisions, invariants, past failures and cross-file workflows source code alone cannot express, stored as Markdown and reviewed through Git like any change.
Claude Code + Obsidian + Graphify
github.comThis is a setup guide combining an Obsidian vault as Claude Code's persistent, Zettelkasten-style memory across sessions with a companion tool, Graphify, that maps a codebase into a knowledge graph, so Claude Code stops re-reading its files every session.
MindMemOS
github.comA portable, self-evolving memory layer for AI agents that stores user and task context and reuses it across agents, automatically distilling recurring experience into reusable skills.
J-Space Cognition Suite
github.comJ-Space Cognition Suite is a model-agnostic, inference-time control system distributed as an installable Skill that organizes an agent's working context into a managed workspace for deep reasoning, tool use, verification and recovery, without changing model weights.
GrapeRoot
graperoot.devGrapeRoot is an open-source launcher that builds a semantic graph of a codebase's files, symbols and call chains, then pre-loads the relevant code into an AI coding assistant's prompt, instead of letting the assistant discover context turn by turn.
deja
vshulcz.github.iodeja is a Go binary that gives coding agents shared memory by indexing session history that Claude Code, Codex, Cursor and 30-plus other agents already write to disk, handing the right one back to whichever agent asks, with no model call or capture step.
