JetBrains AI is an integrated AI-powered coding assistant built directly into all JetBrains IDEs including IntelliJ IDEA, PyCharm, WebStorm, and more. It offers context-aware code generation, automated test creation, multi-file edits via AI chat with RAG-based file discovery, and deep IDE workflow integration. The AI Assistant supports MCP (Model Context Protocol) for connecting external data sources, a /web command for real-time documentation lookup, VCS assistance for commit messages and code reviews, and runtime error explanations. With the 2025.1 release, JetBrains made all AI features accessible for free with unlimited code completion and local model support, while premium features use a credit-based system. The AI Ultimate subscription includes matching AI credits for access to frontier models. Enterprise features include centralized team management, usage analytics, and compliance controls.
