JetBrains AI Assistant
JetBrains AI Assistant is a cross-IDE plugin that weaves large-language-model capabilities into all JetBrains products (IntelliJ-based IDEs, Fleet, Rider, ReSharper and, since 2025, VS Code). It provides:
- Context-aware code completion & chat that marries JetBrains’ static-analysis engine with LLMs
- Refactoring, documentation & commit-message generation triggered directly from the editor
- Multi-LLM routing (OpenAI, Gemini, Meta, JetBrains’ own Mellum) plus optional on-prem/local models
- Enterprise features such as audit logs, admin policy (.noai) and JetBrains AI Enterprise offering
First unveiled in the June 2023 EAP builds, AI Assistant graduated to general availability in December 2023 and, with the 2025.1 release, became free for most use cases, introducing an optional tiered subscription (AI Pro / AI Ultimate) for higher-quota cloud features and Junie, an agentic coding companion.
