JetBrains AI Assistant is the AI layer built directly into JetBrains' IDE family, including IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, PhpStorm, RubyMine, RustRover, CLion, DataGrip, and DataSpell. Built by JetBrains and operated alongside its core IDE business, it brings AI-powered code completion, chat, refactoring help, test generation, documentation, and commit message writing into the editor that JetBrains users already know.
A distinguishing feature is its model routing. Rather than asking users to bring their own API keys, JetBrains AI Assistant gives access to multiple frontier models behind the scenes and automatically routes between them. In 2025 and 2026 the company expanded this with the Junie autonomous agent and direct Claude Agent integration, allowing the IDE to plan and execute longer multi-file tasks on behalf of the developer, while keeping JetBrains' refactoring tools, indexing, and code intelligence in the loop.
Pricing follows a clear ladder. JetBrains offers AI Free with three credits per month and unlimited classic code completion, AI Pro for individuals at around $10 per month, AI Pro for business at around $20 per month, AI Ultimate at around $30 per month for individuals and $60 per month for business, and AI Enterprise with custom pricing. A single subscription works across every JetBrains IDE, which is useful for polyglot developers.
The assistant is best suited to engineers already invested in the JetBrains ecosystem, especially Java, Kotlin, Python, and JVM-heavy teams, who want AI features that respect existing JetBrains refactorings and project structure rather than a separate AI-first editor. It is less attractive to developers who prefer VS Code or terminal-first tools, or who want a single open-ended chat product without an IDE.
