Your AI Agent Has Amnesia. Here's the Fix.

I want to tell you about a problem you've almost certainly run into, probably solved badly, and then quietly accepted as just the way things are. You build an AI agent. It works great in a single session. Then the session ends and it wakes up next time with zero memory of who you are, what you've built together, what it learned. You're back to square one. You patch it. Maybe you dump a big system prompt at the start of every session. Maybe you set up a vector store and hope RAG is good enough. Maybe you just stuff the last N messages into context and pray the token bill doesn't kill you. None of it feels right. Because it isn't. This is the AI memory problem and it's more fundamental than most people admit. * Why the context window is not memory * Here's the mental model that helped me finally understand this clearly: The context window is RAM. It disappears when the process ends. Real memory does three things RAM doesn't: Persists across sessions — it survives restarts Decays intellig
