JetBrains AI Assistant

JetBrains AI Assistant is the deeply integrated AI coding layer inside IntelliJ IDEA, PyCharm, WebStorm and the rest of the JetBrains IDE family, now evolving into the agentic JetBrains Air system.

Overview

JetBrains AI Assistant brings completion, chat, refactoring suggestions, commit message generation and test writing directly into the editor, using full project context from the IDE’s indices rather than just the open file. Because it lives inside the IDE, it understands run configurations, frameworks and build tools, so its answers match the way your project actually works. The 2026 roadmap pushes this further with JetBrains Air, a multi-agent workflow layer that can plan, delegate and verify tasks across the codebase.

The assistant supports cloud-hosted models as well as local and third-party model providers, and lets teams choose which models power which features. Everything is governed by JetBrains AI Enterprise policies for organizations that need control over data flow.

Beyond day-to-day coding help, the assistant connects to Junie, JetBrains’ autonomous coding agent that can take an issue, explore the project and prepare a change for review. Model flexibility is a core design choice: teams can route different features to different providers, use cloud models for speed and switch to local or on-premise models for sensitive repositories. Everything works consistently across the whole IDE line — IntelliJ IDEA, PyCharm, WebStorm, Rider, GoLand and Rider — so polyglot teams get one AI experience rather than a different tool per language.

There is no public inference API; the assistant is exposed through JetBrains IDEs and the JetBrains AI services used by JetBrains products.

How does JetBrains AI Assistant compare to alternatives?

Its advantage is native IDE context — indices, frameworks and run configurations — rather than a generic chat window bolted onto the editor.

Which IDEs include the AI Assistant?

The assistant is available across the JetBrains IDE family, including IntelliJ IDEA, PyCharm, WebStorm, Rider, GoLand and Rider; each gets context-aware features tuned to its language and framework stack.
