Making sense of Google’s agentic dev tools

Making sense of Google’s agentic dev tools

Google released a few cool new AI-assisted developer toys recently. Have you tried them? Do you know which one to use and when? That’s the goal of this talk, to make sense of those new agentic dev tools.

First, we'll start playing with Google AI Studio, to get a sense of the existing models and agents developers can pick up, and we'll see how you can quickly get started vibe-coding apps easily and deploy them in the cloud.

Next, we’ll discover Stitch, an AI-powered tool which helps app builders create high-quality user interfaces for mobile and web apps. You can then eventually export them to vibe code a first prototype with Google AI Studio.

We will look at Antigravity, a new kind of IDE where the main view is actually your AI agent manager dashboard. You plan the work, and autonomous agents execute the tasks. Of course, anytime, you can switch to the more classic code editor with all the smart completions you’d expect.

Last is Jules, a coding agent that lives in the cloud. You can assign Jules boring tasks (fixing bugs or updating tests) and it will work in the background to send you a Pull Request when it is finished.

Join me to see how these tools work in real life. You will leave knowing how to speed up your development and how to become a great boss for your new robot interns!
