# MemoryRouter > MemoryRouter gives AI tools one shared, durable memory. Published hook packages for Claude Code and Codex, remote MCP for editors and CLIs, and connectors for Claude and ChatGPT. ## Product facts MemoryRouter is portable memory for AI tools: one vault that Claude Code, Codex, OpenClaw, Cursor, Windsurf, Cline, Zed, Continue, Claude, ChatGPT and other connected tools read and write. Pricing: 14-day free trial, then $20 per month with 200M memory tokens included, unlimited projects, no inference markup. Published clients: memoryrouter-claude (npm hooks for Claude Code), memoryrouter-codex (npm hooks for Codex), mr-memory (OpenClaw plugin), dsh-memoryrouter (DeepSeek Harness plugin), hermes-memoryrouter (PyPI provider), langchain-memoryrouter (PyPI for LangGraph). Editors and other clients connect over remote MCP at https://mcp.memoryrouter.ai/mcp with OAuth. Claude and ChatGPT connect through custom connectors. Memory scoping: per vault, so a person, a project, or a team gets its own memory. Claude Code and Codex capture the user prompt and the final assistant response per completed turn, excluding tool noise. The OpenAI-compatible endpoint for drop-in memory is https://api.memoryrouter.ai/v1.
