Air is moving into your IDE Earlier this year, we introduced the Air app as our first step into agentic development. Since then, we’ve learned a lot and seen real productivity gains from developers working with agents. As we developed Air further, one thing became increasingly clear: developers don’t need another standalone app. Tools and agents should be built into the environment where you already work. Millions of developers work in JetBrains IDEs every day. So instead of asking you to keep two apps open and constantly switch between them, we’re bringing the Air experience directly into our IDEs, free versions included. Here’s what that means in practice🧵

we've completely rebuilt how AI agents work inside JetBrains IDEs it's called Air, and starting with 2026.3 it ships with all our IDEs Some features: ⛽︎ sign in with your existing ChatGPT, GitHub Copilot or Google account. Claude subscriptions work in terminal view ⛽︎ or bring your own OpenRouter, OpenAI, Anthropic or Gemini API key for supported chat agents ⛽︎ agents work right next to your code, so you can jump into any file they touch without leaving the IDE ⛽︎ hit a limit mid-task? switch to another subscription or API key right in the session, the work keeps going ⛽︎ Claude Agent, Codex, Junie and Copilot work out of the box. add Gemini CLI, Antigravity, OpenCode, Pi and more from the ACP registry, or connect your own agent through ACP ⛽︎ run agents in parallel in separate Git worktrees, then cherry-pick their changes back ⛽︎ agents get the IDE's symbol search, rename refactoring, inspections and run configurations, plus the debugger in IntelliJ IDEA and CLion ⛽︎ Junie Lite is free with a JetBrains account ⛽︎ leave notes on code or diffs and send them to your agent, Claude Code and Codex terminal sessions included ⛽︎ set up MCP servers once for every new agent chat, add skills from folders or GitHub ⛽︎ see at a glance which agents are running and which are waiting for you, use Caps Lock is LED of agents status ⛽︎ review the last turn, roll back individual files ⛽︎ stuck in a merge conflict? hand it to an agent right from the merge dialog ⛽︎ save agent presets and pin the prompts you keep reusing ⛽︎ macOS, Windows, Linux. Remote Development over SSH, WSL and dev containers too and yes, you can change the chat text size and much more features are coming before NY

GitHub Copilot now works with JetBrains Air for coding tasks, guiding execution, and reviewing results. • Run tasks locally in JetBrains IDE or in isolated cloud environments using your Copilot subscription.

Air Teams gives your team shared projects, cloud environments, and automations that run agents when something happens in your repository (like a new pull request) In this video Michelle showcases Air Teams, from the first sign-in to a finished cloud task

Today we're releasing Air Governance. For CTOs and tech leads: track AI usage, manage access, policies and spend org-wide. Any LLM provider. Any dev tool. Truly vendor-agnostic. Top-ups, guardrails, AI metrics, sessions. Battle-tested at JetBrains. Can't imagine going back.
