JetBrains has announced that JetBrains Air, its Agentic Development Environment (ADE) is now available for download on Windows x64 and ARM.

You might not be familiar with JetBrains Air. It's this new desktop app that the company launched back in March 2026 to let developers hand off tasks to AI agents instead of writing every line manually. You can see it as more of an Agentic Development Environment (ADE) rather than a traditional Integrated Development Environment (IDE). The latter builds its features around a central text editor, while the former arranges everything around the AI agent itself. Here's how JetBrains describes it:

The Air desktop app fills the gap between running agents in the terminal and working in a full IDE. It gives you a dedicated environment for agentic development, where you can run tasks, review results, and keep your main coding workflow focused.

Air was born from the ashes of Fleet, an experimental editor that the company quietly killed in December 2025 after realizing that competing directly with VS Code was a losing battle. The company repurposed Fleet's lightweight, modern architecture to build Air, transforming a basic code editor into a workspace for running multiple AI agents. When Air launched, it was only available for macOS. It wasn't until earlier this month that Linux users got a chance to play with the software.

Now that Air is on Windows, you can do things like map out a complex feature in Plan mode and watch an AI write the implementation plan to a markdown file before writing any code. You can iterate on this plan, add references to specific classes or files, and choose whether to run the agent locally or inside an isolated Git worktree. Running agents in parallel means you can have Claude refactor a database schema in one branch while Codex writes tests in another, leaving you free to do other important things. You can even set up a pipeline where Claude writes the code, and Codex reviews it.

At the moment, Air is free. If you have a JetBrains AI Pro or Ultimate subscription, you get full access to the built-in agents, though there is also the option to bring your own key (BYOK) to connect directly to Anthropic, OpenAI, or Google.
