✨⭐Learn the AI tools themselves too
Open the tool guide to learn Codex, NotebookLM, GitHub, Vercel, and more in kid-friendly steps with Garu-chan.
✨⭐Level-based paths
Beginners should focus on learning one tool at a time.

Beginner
Start with one tool only and repeat the basic flow: open it, ask, and summarize. NotebookLM is a great first choice.
NotebookLMIntermediate
Once you are comfortable with one tool, combine tools like Codex or Veo to build projects. It helps to separate thinking tools from making tools.
