Who it's for
Best for
Developers working in JetBrains IDEs who want AI agents inside their editor
Teams already on JetBrains IDEs who need several model providers on one bill
Not for
Heavy agent users who need long monthly quotas before topping up- Developers running local models or own API keys who expect no usage limits
Features
Runs in IDE, browser, CLI and mobile
Air runs agents in JetBrains IDEs, the browser, the command line and on mobile, with cloud runs keeping work tied to a project rather than one machine.
Connects existing agents
Claude Agent, Codex, Junie, Copilot and OpenCode are recognized agents, and further agents connect through ACP or the agent registry.
Parallel project tracking
Several projects stay open at once, each with its own sessions, unread updates, changed files and outgoing commits listed for tracking.
Review changes in context
Diffs open directly from an agent session, changes are validated with IDE tools, and comments on specific lines guide the agent's next action.
Flexible AI access
An existing provider subscription, API keys or a base URL can be used, and subscriptions can be switched mid-session.
What users say
Pros
- Diffs and IDE review tools sit in the editor, which makes checking AI-written edits in large unfamiliar codebases far easier.
- One subscription covers Claude for planning and GPT for implementation, so a second AI bill is not needed.
- Global and keyword search plus find-dependencies work straight from the IDE panel on a large .NET codebase without extra setup.
- Gemini requests through the JetBrains account finish a task in about three minutes, against half an hour through a Google account.
Cons
- A month's credit allowance disappears within a few hours of agent work, leaving the rest of the month on top-ups.
- Credits get consumed while working through a company Claude subscription, a local Ollama model or an own API key.
- After almost every IDE update the newest model disappears from the model picker and stays missing for days.
- Junie falls back to command-line tools and hundreds of slow hand edits instead of the IDE build and refactoring tools.
- The chat, assistant and Junie panels overlap, the agent window is sluggish, and output is badly formatted and hard to read.
- Applying an assistant suggestion garbles source files about one time in ten or twenty.
