JetBrains opened early access for Air inside its IDEs on October 1, 2026. The post describes the Air plugin as a conduit for agents and subscriptions a developer already uses. It is not an AI provider, and it ships with no agents installed. The early access is available as JetBrains Marketplace plugin 33314, or natively in the 2026.3 EAP builds. Air detects agents already on the machine, the way the IDE detects a terminal. Nothing runs, and no data leaves the machine, until the user signs in to an agent or a JetBrains AI plan. If an organization does not allow agents, JetBrains says there is nothing for Air to run and nothing to send. Local use of those existing agents does not require a JetBrains AI subscription. Out of the box, Air supports Codex, Gemini, GitHub Copilot, Claude Agent, and Junie. The same post also names Cursor among agents it can bring into the IDE, and says many others can be connected through ACP. A Claude subscription can be used in Air’s terminal surface, which opens as a full-screen IDE tab. With a third-party subscription, data goes directly to that provider under the agreement the user already has. It does not pass through JetBrains. If the user chooses JetBrains AI instead, the existing JetBrains AI Terms of Service apply. Air adds no new data processing terms. Cloud runs are the part that still needs JetBrains. The FAQ says a JetBrains AI subscription is currently required for cloud runs. Separately, the product walkthrough says running agents in the cloud, then closing the machine, is currently available to organizations with AI seats. Following those runs on mobile is described as coming soon. Junie Lite, offered free so people can try Air without paying, is a coding agent with a cost-efficient model for everyday tasks. Access requires a JetBrains Account. The free offer applies to the Junie Lite configuration after sign-in, and JetBrains says terms and available models may change. The reason for a new surface, rather than another chat pane, is parallel work. JetBrains says it tried adding more agents to AI Assistant’s chat and found that orchestrating several tasks at once is different from a conversation with AI. Air keeps sessions visible in one place across projects, including activity, unread updates, changed files, outgoing commits, and what each session costs. A new session starts with a double-tap of Ctrl from anywhere in the IDE, with the current context already attached. Sessions can open as editor tabs, stay in a terminal UI, or use a graphical chat. Parallel work can be isolated with temporary worktrees: start from any branch, on a new branch or detached, track changes and commits from the chat, then cherry-pick the result back into the main project. Supported agents also get built-in IDE skills and tools for debugging, performance profiling, database exploration, and semantic code search. JetBrains says that can help agents produce better results and, for some tasks, use fewer tokens. Review stays in the IDE, through diffs, navigation, and inspections. AI Assistant is not retired. JetBrains expects Air to become the primary experience for agentic workflows in its IDEs over time, but says AI Assistant will remain available and supported as a separate Marketplace plugin. Installing Air from the notification inside AI Assistant disables AI Assistant so the two do not run side by side. It can be re-enabled in Settings | Plugins, or reinstalled from Marketplace. Disabling the Air plugin leaves the rest of the IDE unchanged. The October 1 post presents this IDE early access as the follow-on to JetBrains introducing Air the previous week as an open system of products for agentic development. Feedback goes to YouTrack project IJAI or the comments on the post. To try the local path, install Marketplace plugin 33314 or open a 2026.3 EAP build, connect an agent you already use, and start a session with a double-tap of Ctrl. Read the October 1 post before turning on cloud runs: they currently require a JetBrains AI subscription and, per the walkthrough, are available to organizations with AI seats. Junie Lite requires a JetBrains Account after sign-in and is not a JetBrains AI subscription. ## Sources - [A New Agentic Experience\: JetBrains Air in IDEs – EAP Now Open](https://blog.jetbrains.com/ai/2026/10/air-in-ides-eap/)
