What it does

JetBrains AI is a set of AI solutions built around the JetBrains IDEs. The site says it pairs the company's own models with other leading AI, so developers decide how much AI to use, ranging from light help to heavier automation, and can pick the agents and providers they prefer. Junie is a coding agent that plans, writes, refines and tests code. JetBrains Air is an environment for running agents in which Codex, Claude Agent, Gemini CLI and Junie each carry out separate task loops in parallel. Koog is an open-source framework for building AI agents on the JVM in Kotlin or Java, and Mellum is a family of fast language models described as open source. For organizations, the site describes management and governance features that show how teams use AI, plus on-premises options for control over data and models. It states that customer code and data are not used to train its models and that its proprietary models are trained only on public, permissively licensed code.
