How to add persistent memory to your AI agent

What it is
Persistent memory for AI agents is like giving them a notebook they can reference later. Without it, your agent forgets everything the moment a session ends—you're always starting from zero. With memory APIs, agents can store facts, preferences, and context in structured storage, then retrieve them in future conversations. Picture a developer assistant that remembers your coding style, project structure, and past debugging sessions.
Why it matters
If you're building agents for real workflows—customer support, personal assistants, dev tools—memory is the difference between a chatbot and an actual assistant. This tutorial shows you how to implement it using Google's ADK, which means you're not hacking together your own database layer. Worth exploring if you're tired of re-explaining context to your agent every time you open it.
Key details
- •Tutorial uses Google's Agent Development Kit (ADK) with built-in memory APIs
- •Covers both the lab walkthrough and full ADK documentation for implementation
- •Includes a dedicated ADK session video walking through the memory feature
- •Memory persists across sessions, not just within a single conversation thread
- •Aimed at developers building agents that need long-term context tracking
