🌱 A Gentle Introduction

What is Memento? Imagine you're solving a complex bug, figuring out a tricky configuration, or establishing a new coding pattern. Usually, you'd forget the details in a few weeks. Memento is a "long-term memory drive" for your AI assistant. It allows your AI to save these solutions, decisions, and facts so it can recall them instantly across different projects, even months later.

💡 The Agentic Mindset: A Guide for Traditional Developers If you are used to deterministic software (where things happen automatically because a script says so), interacting with AI agents requires a slight mental shift.

Memento is not an autonomous agent that watches your screen and magically decides what to remember. Instead, Memento is a toolbelt provided to your AI assistant (like Claude, Cursor, or Gemini).

  • The AI is the worker: It needs to be told when to use the toolbelt. Nothing is saved without explicit instruction or a pre-defined rule.
  • You are the manager: You control what gets stored. You can either tell the AI during a chat ("Save this database connection string"), or you can give the AI standard operating procedures (via system prompts or .cursorrules/CLAUDE.md files) so it knows to automatically save certain things, like bug fixes or architecture decisions.

How to build the habit:

  1. Start of session: Ask your AI, "What do we know about the authentication system?" to pull context.
  2. During work: When you fix a tricky issue, say, "We fixed the Redis timeout. Store this solution."
  3. End of session: Tell your AI, "Store a summary of what we accomplished today."

Alternatively, you can add custom instructions to your AI (see our Agent Configuration Guide) to make it automatically execute these steps without you having to ask every time.
