Why AI Agents Need Long-Term Memory to Be Truly Useful Every AI agent you've built has the same fatal flaw: amnesia. Your chatbot nails the first conversation. The user says they prefer dark mode, work in fintech, and hate verbose responses. Perfect — the agent adapts. Then the session ends, and it's all gone. Next conversation? "Hi!
