JetBrains AI Assistant has matured significantly — a free tier, Junie agent integration, and bundling with the All Products Pack make it worth using on real projects for teams already in the JetBrains ecosystem.
Why It Moved from Assess to Trial
When this entry was first written in January 2025, JetBrains AI was catching up to Copilot and Cursor. Since then:
- Free tier launched (2025.1): Unlimited code completion + local model support for all JetBrains IDE users, removing adoption friction
- Junie agent integration (Jan 2026): JetBrains' own coding agent, built on Claude Agent SDK with MCP support — handles multi-step tasks autonomously within the IDE
- Bundled with All Products Pack: AI Pro ($8/mo) is included free for All Products Pack subscribers — effectively free for many professional developers
- Multi-file edit mode: AI chat can now propose changes across multiple files with reviewable diffs
- Model flexibility: GPT-5, Claude 4.x, Gemini, plus local models via Ollama/LM Studio
Pricing (credit-based, as of September 2026)
JetBrains moved AI from flat monthly plans to a credit model — 1 AI Credit = USD 1.00 (valid 12 months), with anytime top-ups.
| Plan | Price | What you get |
|---|---|---|
| AI Free | $0 | 3 AI credits / 30 days; IDE-native completion, BYOK, local models |
| AI Pro | $100/user/year | 10 AI credits / 30 days; regular agent use |
| AI Ultimate | $300/user/year | 35 AI credits / 30 days; frequent coding-agent use |
| AI Enterprise | $720/user/year | Max credits, enterprise security, custom AI integrations |
JetBrains Central and Air (March 24, 2026)
JetBrains announced JetBrains Central, a governance and execution platform for AI agent fleets (Anthropic, OpenAI, and Google Cloud are launch partners), and JetBrains Air, a dedicated multi-agent development environment now in public preview. Of the 11,000 developers surveyed in the January 2026 JetBrains AI Pulse survey, 90% reported already using AI at work. Both are early — see the dedicated JetBrains Central and JetBrains Air entries for detailed assessments.
When to Choose JetBrains AI
- You're already on IntelliJ, PyCharm, WebStorm, or another JetBrains IDE and don't want to switch
- You want deep IDE integration with JetBrains' code analysis (PSI, type info, refactoring engine)
- Your team uses the All Products Pack (AI Pro is effectively free)
- You work primarily in Java/Kotlin where JetBrains' code understanding is strongest
