# Build with Mem0

Universal, self-improving memory layer for LLM applications.

**Add memory to your app**  
[Start with the quickstart and store your first memory in minutes.](https://docs.mem0.ai/platform/quickstart)

**Add memory to your agent**  
[Give Claude Code, Cursor, and Codex memory that persists across sessions. A drop-in plugin, no code to write.](https://docs.mem0.ai/integrations/claude-code)

**Sign up for Mem0 as an agent**  
[Let an AI agent mint a Mem0 API key, claim ownership later, and write its first memory from the terminal.](https://docs.mem0.ai/platform/agent-signup)

**Explore Mem0 integrations**  
[Connect Mem0 to LangChain, CrewAI, Vercel AI SDK, and 20+ partner frameworks.](https://docs.mem0.ai/integrations)

**See memory-app examples**  
[Browse cookbooks for companions, support agents, voice agents, research tools, and more.](https://docs.mem0.ai/cookbooks/overview)

**Self-host Mem0**  
[Use Open Source when you want memory without the hosted platform.](https://docs.mem0.ai/open-source/overview)
