JetBrains Junie is JetBrains’ own AI coding agent, built into the IDEs millions of developers already use — IntelliJ, PyCharm, WebStorm, GoLand and the rest.
- From JetBrains, makers of IntelliJ and the Kotlin language (25+ years of IDE tooling).
- Delegate routine tasks or collaborate on complex ones, with a plan you review.
- Backed by the IDE’s deep index — it knows your project’s structure.
- Now joined by Junie CLI and the agent-first Air environment (2026).
Junie leans on JetBrains’ code intelligence and frontier models.
- Powered by Claude (Anthropic) and OpenAI models.
- Reads project structure, logic and relationships via the IDE index.
- Runs code and tests, verifying the project still builds after changes.
- Available across IntelliJ IDEA Ultimate, PyCharm Pro, WebStorm, GoLand and more.
Bundled into the JetBrains AI subscription, with a free tier.
Junie is for developers committed to the JetBrains ecosystem.
- JetBrains IDE loyalists (IntelliJ, PyCharm, GoLand…).
- Java/Kotlin and Python teams already on JetBrains tooling.
- People who want an agent that respects the IDE’s project model.
- VS Code-centric developers.
- Anyone who wants a model-agnostic, bring-your-own-key setup.
No tool is perfect — the trade-offs to weigh:
- JetBrains-only — no help outside their IDEs.
- Requires a JetBrains subscription for full use.
- Cloud models — Junie doesn’t run fully local.
- Younger than Copilot or Cursor as an agent.
- ✓Deeply native to JetBrains IDEs and their code index
- ✓Code + Ask modes for delegating or collaborating

JetBrains users like that Junie feels part of the IDE rather than bolted on — it understands the project and runs tests like the IDE does. Reviews are mixed on autonomy: some find it a real time-saver on routine tasks, others feel it’s still catching up to Copilot and Cursor on harder work. Sentiment is positive among committed JetBrains developers and cooler outside that world.
Junie is built by JetBrains, the long-established maker of IntelliJ IDEA, PyCharm and the Kotlin language.
