Learn more about the public preview

Explore

Interact with your codebase naturally using the built-in AI chat. Ask questions, refine prompts as you go, and get answers tailored to your specific project and programming language.

Code

Speed up coding with smart completions for single lines or entire blocks across popular languages like Java, Kotlin, Python, JavaScript, C#, C++, and TypeScript. Powered by Mellum, the JetBrains LLM built for developers, completions are fast, accurate, and syntax-aware.

Harness collaborative AI with Agentic mode – an orchestration of multiple models solving complex problems under your supervision. You stay in control, guiding AI Assistant as it tackles your tasks.

Improve

Let AI explain confusing code, identify potential bugs, and suggest optimizations on the fly. Ready to implement changes? Switch to Edit or Agentic mode and to apply changes to multiple files directly from your conversation.

A notice on language support

JetBrains AI Assistant does not provide language support features like code highlighting, code analysis, or refactoring. To access those capabilities, you may want to install a corresponding language support extension. For C#, we recommend using ReSharper for VS Code.

During the public preview, you can either use your current JetBrains AI subscription or, if you don’t have one, automatically get a free AI EAP license once you log in with your JetBrains Account. JetBrains AI Plans will apply after the full public release.
