Junie

AI coding agent by JetBrains for autonomous task execution

open sourceupdated Aug 16, 2026

Junie is JetBrains’ AI coding agent for autonomous task execution inside JetBrains IDEs and Android Studio. It helps plan implementation steps, write and inspect code, run tests, and collaborate through code and ask modes. Current JetBrains AI positioning lists Claude, GPT, Gemini, Grok, local-model options, and provider-choice paths, with AI Ultimate recommended for regular Junie usage.

Junie is JetBrains’ AI coding agent for developers who already work in JetBrains IDEs such as IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, RubyMine, RustRover, Rider, CLion, and Android Studio. Instead of presenting the agent as a standalone benchmark result, the current product page emphasizes IDE-native workflows: Junie can propose a plan, adjust between code and ask modes, write code, run checks, and use IDE syntax and semantic analysis to keep changes aligned with the project.

The model and provider story is now part of the wider JetBrains AI surface. JetBrains lists Claude, GPT, Gemini, Grok, and local-model options, plus a multi-agent experience that includes Junie alongside other agents and ACP-connected tools. That positioning gives teams flexibility, but it also makes subscription and credit planning important: AI Pro is framed as a way to try Junie, AI Ultimate is recommended for regular Junie use, and AI Enterprise targets daily team usage with enterprise controls.

Junie is strongest for teams that already value JetBrains project indexing, inspections, refactoring support, and test workflows. The tradeoff is packaging complexity: organizations must evaluate IDE licensing, JetBrains AI credits, and any provider-key strategy together. CLI-specific and benchmark-specific claims should be checked against the latest JetBrains documentation before being used as buyer-facing proof points.

Comparisons

Junie vs JetBrains AI: Autonomous Agent or Everyday Assistant?

Junie and JetBrains AI are not fully separate purchases: Junie is the autonomous coding-agent workflow available through JetBrains AI plans, while AI Assistant provides completion, chat, explanations, and guided edits. Junie wins when the buyer's primary need is multi-step implementation, but AI Assistant is the better everyday layer for developers who mainly want help while staying in direct control.

Junie vs Cursor: JetBrains-Native Agent or AI-First Editor?

Junie and Cursor both execute multi-step coding tasks, but Junie is shaped by JetBrains project intelligence while Cursor is an AI-first editor and agent platform. Cursor is the stronger default across languages and repositories; Junie becomes the better choice for teams already committed to IntelliJ-platform inspections, run configurations, tests, and debugger workflows.
