JetBrains' AI coding agent built into IntelliJ-family IDEs, licensed through the JetBrains AI plans.

Profile

JetBrains Junie is an AI coding agent built by JetBrains that works directly inside JetBrains IDEs, exploring your project, planning an approach, writing and testing code, and letting you review or refine the result rather than just autocompleting single lines.

Who builds it

Junie is developed by JetBrains, the company behind IntelliJ IDEA, PyCharm, and the wider JetBrains IDE family, and is distributed as a plugin/feature inside those existing IDEs rather than a separate standalone editor.

Core features

  • Seamless IDE integration: runs inside the IDE you already use, without requiring a separate app or context switch.
  • Codebase-aware planning: explores project structure and logic before proposing a plan, instead of jumping straight to code.
  • Two working modes: a code-execution mode where Junie writes, runs, and tests changes, and a collaborative ask mode for discussion before anything is applied.
  • IDE-backed quality checks: leverages the IDE's own static analysis for syntax and semantic validation of generated code.
  • Test integration: runs the project's tests and verifies changes rather than assuming they work.
  • Broad IDE coverage: available in IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, RubyMine, RustRover, Rider, CLion, and Android Studio.

Pricing

Junie's usage is metered through JetBrains' shared "AI Credits" system rather than sold as its own separate subscription:

  • AI Free: no cost, 3 AI Credits every 30 days, plus unlimited IDE code completion and context-aware chat.
  • AI Pro: $100/year (about $8.33/month), 10 AI Credits every 30 days, with the option to buy extra credits anytime.
  • AI Ultimate: $300/year (about $25/month), 35 AI Credits every 30 days — JetBrains positions this tier for people who use Junie or other agentic features frequently.
  • AI Enterprise: $720/year (about $60/month) list price, with the largest credit allocation, enterprise security features, and custom integrations available on request.
  • A 30-day AI Pro trial is available, and AI Credits are valued at $1 each and remain valid for 12 months from purchase.

Because agentic runs like Junie's consume credits faster than simple completions or chat, the free tier's 3 monthly credits are realistically enough only for light evaluation rather than daily agent use.

Who it's for

Developers already working inside a JetBrains IDE who want an agent that understands their existing project setup rather than switching to a separate AI-first editor. It suits both individual developers testing agentic workflows on the free tier and teams standardizing on JetBrains tooling who want predictable, credit-metered access to frontier models through AI Pro, Ultimate, or Enterprise.

Frequently asked questions

Is JetBrains Junie free?

There is a free AI tier that includes Junie access, but it's capped at 3 AI Credits every 30 days, which covers light evaluation rather than daily agentic use since agent runs consume credits faster than simple chat or completions. Regular use typically requires AI Pro, Ultimate, or Enterprise.

What does JetBrains Junie cost?

Junie doesn't have its own separate price; it's metered through JetBrains' shared AI Credits plans: AI Free (3 credits/30 days), AI Pro at $100/year (10 credits/30 days), AI Ultimate at $300/year (35 credits/30 days), and AI Enterprise at $720/year list price with the largest credit allocation.

Which IDEs support Junie?

Junie works across the JetBrains IDE family, including IntelliJ IDEA, PyCharm, WebStorm, GoLand, PhpStorm, RubyMine, RustRover, Rider, CLion, and Android Studio, rather than being limited to a single editor.

How does Junie work — does it just autocomplete code?

No, Junie is an agent rather than a line-level autocomplete tool: it explores your project's structure and logic, proposes an execution plan, then writes and tests code (or discusses the approach first in ask mode), using the IDE's own static analysis to validate what it generates.

What is the difference between AI Pro and AI Ultimate for Junie users?

AI Pro costs $100/year and includes 10 AI Credits every 30 days, aimed at regular AI-enhanced IDE workflows, while AI Ultimate costs $300/year for 35 AI Credits every 30 days and is positioned for people who use Junie or other agentic features frequently. Both allow buying extra credit top-ups anytime.

Is there an Enterprise plan for Junie?

Yes. JetBrains AI Enterprise lists at $720/year and includes the largest AI Credit allocation, enterprise security features, and custom AI integrations, with JetBrains requesting a demo request for full details rather than self-service signup.
