OzBrain is described as 'Shared brain every AI agent you use can read and write. One structured source of truth across Claude, ChatGPT, Cursor, and coding agents' and is an app in the ai tools & services category. There are more than 10 alternatives to OzBrain for a variety of platforms, including Web-based, SaaS, Self-Hosted, Linux and Mac apps. The best OzBrain alternative is Claude-Mem, which is both free and Open Source. Other great apps like OzBrain are LedgerMind , Mem0, Memoir and SAME (Stateless Agent Memory Engine).
A Claude Code plugin that automatically captures everything Claude does during your coding sessions, compresses it with AI (using Claude's agent-sdk), and injects relevant context back into future sessions.
LedgerMind is a next-generation autonomous memory core for AI agents that achieves genuine zero-touch operation. Using client-side hooks, it automatically: • Searches and injects the most relevant memories before every user prompt • Logs all agent actions including tool calls...
Mem0 is a self-improving memory layer for LLM applications, enabling personalized AI experiences that save costs and delight users. Mem0 remembers user preferences, adapts to individual needs, and continuously improves over time.
Memoir is a high-performance semantic memory system for AI agents that brings Git-like version control to AI memory management. It replaces opaque vector databases with transparent, versioned, cryptographically secure memory storage using hierarchical semantic paths.

Local-first memory engine for AI coding agents featuring 12 MCP tools for context search, decision tracking, session handoffs, and knowledge graphs. Runs as a single Go binary with local embeddings, 17 knowledge vaults, and supports multiple MCP editors securely.
A local-first, open-source long-term graph memory engine for AI agents and developers that actively fights knowledge drift and eliminates context bloat using a local 3-model ML stack including NLI.
Serbia
ChainMemory gives AI agents persistent memory that belongs to the user, not the vendor. Save a memory in ChatGPT and recall it in Claude, Gemini, Perplexity or Copilot via Chrome extension, MCP server, or REST API.
Haki gives any AI agent a memory that lasts for months dated, sourced, and provable. Self-hosted on your own Postgres, Apache-2.0, no amputated edition.
Mali
MemoryBase turns your AI conversations across ChatGPT, Claude, Claude Code, Cursor, and Gemini into one searchable memory, so every response feels tailored.
United States
MemoryPlugin gives AI the ability to remember you — your preferences, history, and context — across chats and tools. No more starting from zero. Enjoy smarter, faster, and more useful conversations that help you accomplish more.
Open-source, self-hosted MCP server for project intelligence, semantic search, context engineering, and persistent agent memory for AI coding agents.
Switzerland
Maximem Synap is a managed long-term memory layer for AI agents. It stores what an agent learns across sessions and returns the relevant parts at inference time, instead of re-sending an entire conversation history into the context window.
