AI coding assistant deeply integrated across the JetBrains IDE family with in-editor chat, code completion, test generation, and multi-provider model choice.
Deeply integrated AI coding assistant across the JetBrains IDE family from the Czech-based maker of IntelliJ, PyCharm, and WebStorm.
JetBrains AI Assistant is a deeply integrated AI coding companion that runs inside every JetBrains IDE (IntelliJ IDEA, PyCharm, WebStorm, GoLand, CLion, Rider, RubyMine, PhpStorm, and more), delivering in-editor chat, inline code completion, automatic test generation, commit message drafting, and refactoring suggestions. It leverages the IDE's own static analysis so completions understand the full project context, not just the nearby text.
Unlike plugin-first competitors, the assistant is built by the makers of the IDE itself, so features like project-aware refactoring, safe code transformations, and JetBrains' award-winning code inspections feed directly into AI prompts. Users can choose between multiple underlying models and plug in local LLMs via Ollama or LM Studio for fully offline work.
Key benefits:
- Native IDE integration gives the AI access to full project context and static analysis
- Multi-model choice with OpenAI, Anthropic, Google, and local Ollama / LM Studio options
- Inline completion and chat work together across every JetBrains IDE seamlessly
- Commit message generation and automatic test writing accelerate day-to-day flow
- Free quota available for personal learning and evaluation
- AI agents automate multi-step refactors and cross-file changes inside the IDE
