Below are the answers to some common questions. If you don’t find the answer to your question, feel free to contact junie@jetbrains.com. JetBrains Junie is an AI-powered coding agent by JetBrains designed to handle tasks autonomously or in collaboration with a developer. Developers can fully delegate routine tasks to Junie or partner with it on more complex ones. Junie will explore the project for you, write code that fits, run tests if needed, and share the result for your review. With the power of JetBrains IDEs, coupled with reliable LLMs, Junie quickly solves tasks that require hours of work. When you use AI-powered features, the IDE needs to send your requests and code to the LLM provider. In addition to the prompts you type, the IDE may send additional details, such as pieces of your code, file types, frameworks used, and other information that is necessary for providing the LLM with sufficient context. Additionally, in EAP builds, we collect anonymous data about AI feature usage, including all of their communication with the LLM (both text and code fragments). This data is kept strictly confidential and is used by JetBrains for product improvement purposes only. JetBrains offers a variety of tools that increase developer productivity. Many of these tools complement each other and fit well in JetBrains IDEs. The difference between JetBrains Junie and JetBrains AI Assistant is the level of autonomy and collaboration available with the coding agent. While AI Assistant supports developers with unique functionality to code faster, Junie operates more independently and collaboratively with a developer, solving larger tasks step by step. Developers may fully delegate a task to Junie or partner with it on a more complex one. Junie will explore the project for you, write code that fits, run tests if needed, and share the result for your review. There may be projects where it makes sense to use both Junie and AI Assistant for different tasks, as they complement your work in different ways. For now, JetBrains Junie is in Early Access Program and compatible only with IntelliJ IDEA Ultimate and PyCharm Professional. For now, Junie is compatible with JetBrains IDEs, such as IntelliJ IDEA Ultimate and PyCharm Professional. If you use one of these products, you may join the waitlist for the chance to be among the first to use Junie. Access to JetBrains Junie and JetBrains AI services is currently restricted to the territories where OpenAI or Anthropic is available. You can check the full list of territories here. The Early Access Program is a phase where a product, feature, or tool is made available to a limited group of users before its full public release. Participants often gain early access to innovative tools or features, and their input helps shape the final version. Starting January 23, we invite JetBrains users to join the Early Access Program for the chance to be among the first to try JetBrains Junie. Junie is powered by different configurations, including external providers, such as Anthropic and OpenAI. We do our best to make sure that we use the best possible model and that we get maximum value from the model we use. However, this may change depending on how Junie performs with other products. Junie is being released in an Early Access Program, where it will be available to a limited number of users. We are committed to providing access to as many users as we can. However, we ask for your understanding that not everyone can be among the first to try it. Currently JetBrains Junie is available for IntelliJ IDEA Ultimate and PyCharm Professional. For the time being, JetBrains Junie is only available to users of IntelliJ IDEA Ultimate or PyCharm Professional. Click here to learn more about JetBrains IDEs.
