Install Extension

Install by editor

Pick your editor and follow the steps below.

Antigravity (recommended)

1. Open Antigravity. If you don’t have it, grab it from antigravity.google.
2. Open the Extensions sidebar (Ctrl+Shift+X on Windows/Linux, Cmd+Shift+X on Mac).
3. Search for “Jetro” and click Install.

Or from the terminal:

antigravity --install-extension jetro-ai.jetro

VS Code

1. Open VS Code. If you don’t have it, grab it from code.visualstudio.com.
2. Open the Extensions sidebar (Ctrl+Shift+X on Windows/Linux, Cmd+Shift+X on Mac).
3. Search for “Jetro” and click Install.

Or from the terminal:

code --install-extension jetro-ai.jetro

Cursor

3. Search for “Jetro” and click Install.

Or from the terminal:

cursor --install-extension jetro-ai.jetro

Set up your AI agent

Jetro needs a coding agent to work. Here’s how to get one running.

Antigravity

Antigravity ships with Claude Opus, Claude Sonnet, and Gemini built into its agent chat. If you’ve got a Google AI Pro or Ultra subscription, you can use Antigravity’s agent chat directly. We recommend picking Claude Opus or Claude Sonnet as your coding companion.

That said, for the best experience with Jetro we recommend installing Claude Code separately:

1. Open the Extensions sidebar (Cmd+Shift+X).
2. Search for “Claude Code” and click Install.
3. Sign in with your Claude Pro or Claude Max subscription.
4. Claude Code picks up Jetro’s tools automatically through the MCP config file. No manual setup needed.

VS Code

1. Open the Extensions sidebar (Ctrl+Shift+X / Cmd+Shift+X).
2. Search for “Claude Code” and click Install.
3. Sign in with your Claude Pro or Claude Max subscription.
4. Claude Code picks up Jetro’s tools automatically. No manual setup needed.

Cursor (already built in)

Cursor ships with built-in AI agents. If you’ve got a Cursor Pro or Business subscription, you already have an agent. Jetro’s tools plug in automatically. No extra setup.

You can also install Claude Code inside Cursor if you prefer using Claude.

Once you’re set up, head over to Your First Canvas for a complete cold-start walkthrough.
