JetBrains AI

JetBrains AI is an integrated ecosystem of intelligent tools embedded directly into the JetBrains IDE family and supported environments like VS Code. It combines proprietary models, such as the code-completion-optimized Mellum, with leading third-party LLMs from providers like OpenAI, Anthropic, and Google.

The platform offers a range of specialized tools: AI Assistant for context-aware coding, refactoring, and commit generation; Junie, an agentic coding assistant for planning and testing; and specialized integrations like YouTrack for project management and Datalore for data science.

Unlike external plugins, these features leverage the IDE's deep structural analysis of your codebase to ensure refactoring and code comprehension are accurate and safe. JetBrains prioritizes developer control and privacy, explicitly stating that user code and data are never used for model training.

The platform supports a modular approach, allowing developers to choose their preferred AI model or switch to deeper automation features. It is designed to minimize repetitive tasks, facilitate pair programming via intelligent agents, and provide enterprise-grade security for organizations needing full control over their AI usage and compliance.
