Choose Mem0 if you are building your own AI app and want an open-source memory SDK that extracts user preferences and facts from conversations, with a large ecosystem of vector stores and LLMs.
Choose OwlMem if you want the AI tools your team already uses — Claude, ChatGPT, Cursor, Codex — to share one memory without writing code, with readable Markdown history and a vault for credentials.
They work at different layers, so they can sit side by side: Mem0 inside a product you ship to your users, OwlMem for the AI agents your team works with every day. Mem0 also offers a hosted MCP server; if you have used it for personal coding-agent memory and want to share with a team, ask your agents to save what matters into OwlMem with kb_write and kb_retain — there is no automatic importer.
Yes. The Mem0 library is open source under Apache-2.0 and can be self-hosted. Mem0 Platform is the hosted version, with a free tier and paid plans from $19 a month (as of October 2026).
No. OwlMem doesn't read your chat transcripts. Agents decide what is worth keeping and save it with kb_write (pages) or kb_retain (facts), guided by your team rules. That keeps the knowledge base readable and avoids storing conversations you didn't mean to keep.
Yes, both through MCP. Mem0's hosted MCP server lists Claude, Claude Code, Codex, Cursor, Windsurf and VS Code. OwlMem works with any MCP client, including ChatGPT, and every AI connects under its own identity, so you can see which agent wrote what.
