JetBrains AI Assistant is the built-in AI coding feature for the entire JetBrains IDE family — IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, DataGrip, and more. It is developed and maintained by JetBrains, the Czech company behind what remains the most widely used professional IDE suite in enterprise software development. Unlike GitHub Copilot or Cursor, which require installing a plugin or switching editors, JetBrains AI is native to the IDE — it understands JetBrains’ own refactoring, inspection, and code analysis systems and can leverage them directly. For developers already in the JetBrains ecosystem, it is the lowest-friction AI upgrade. For developers not already using JetBrains, it is not a reason to switch.
What It Does
JetBrains AI Assistant adds AI capabilities directly into the IDE experience JetBrains developers already use. Inline code completion (AI Full Line) predicts the next statement or block as you type, augmenting JetBrains’ existing autocomplete rather than replacing it. The chat panel (AI Chat) answers questions about your code, explains JetBrains inspections, suggests fixes, and generates new code. Code generation is aware of the current project’s structure, frameworks, and dependencies as indexed by the IDE. AI Actions provide quick commands: explain code, generate documentation, write unit tests, review diffs, and generate commit messages. JetBrains AI connects to cloud models (including Claude and OpenAI) and adds JetBrains’ own model for local completion.
Who It’s For
- Existing JetBrains IDE users who want AI without installing a separate extension or switching editors
- Java and Kotlin developers using IntelliJ IDEA, where JetBrains’ code intelligence is deepest
- Python developers in PyCharm who want AI integrated with PyCharm’s type checker and debugger
- Teams on JetBrains All Products license who can add AI Assistant at a lower marginal cost
- Enterprise teams who value a single vendor relationship for IDE and AI tooling
- Developers who find VS Code-based tools unsuitable for their workflow (Cursor is VS Code only)
Pricing
| Plan | Price | Key Limits |
|---|---|---|
| AI Free | $0/mo | Limited AI completions and chat; included with IDE |
| AI Pro (annual) | $8.33/mo | Full AI features; billed as $100/year standalone |
| All Products + AI (annual) | $16.67/mo | All JetBrains IDEs + AI; billed as ~$200/year |
Verification note: JetBrains AI pricing confirmed at jetbrains.com/ai as of 2026-04-14. Prices shown are annualized monthly equivalents; JetBrains bills annually.
Key Features
- Deep IDE integration: AI understands JetBrains inspections, refactorings, run configurations, and project structure — not just open files
- AI Full Line completion: predicts entire statements or blocks inline without a separate extension
- AI Chat: ask questions about your code, explain errors, generate tests, review diffs
- Commit message generation: automatically writes Git commit messages from staged diff
- AI-powered code review: summarizes changes and flags potential issues in pull request diffs
- Works across all JetBrains IDEs: one subscription covers IntelliJ, PyCharm, WebStorm, GoLand, Rider, DataGrip, etc.
- Language-specific awareness: understands Spring Boot, Django, React, and other framework patterns specific to each IDE
Limitations
- Only useful if you use JetBrains IDEs. There is no VS Code version. Developers in other editors cannot use it.
- Annualized pricing increases cost. JetBrains bills annually, not monthly. The $8.33/mo figure requires paying $100 upfront. Month-to-month is more expensive.
- Agent mode is limited. JetBrains AI can edit across files but does not have the autonomous multi-step capability of Cursor’s Composer or Claude Code.
- The model is not best-in-class. JetBrains routes to major model providers but the integration lags behind tools purpose-built for AI (Cursor’s tab completion is better).
- Completion quality below Cursor and Copilot. For raw autocomplete quality on complex code, both Cursor and Copilot produce better completions.
Bottom Line
JetBrains AI Assistant earns solid scores for longevity (8/10) and moat (7/10) — JetBrains has a large and loyal enterprise user base that will not easily migrate away. Utility (7/10) reflects genuine usefulness within the IDE combined with capability gaps versus Cursor. For existing JetBrains users, especially on the All Products license, adding AI Assistant is a low-cost, low-friction upgrade. For developers not already in the JetBrains ecosystem, Cursor or Copilot are stronger choices.
Best Alternatives
| Tool | Price | Key Difference |
|---|---|---|
| GitHub Copilot | $10/mo | Works in JetBrains too, stronger model selection |
| Cursor | $20/mo | VS Code only, but best AI IDE experience available |
| Cody | $9/mo | JetBrains plugin with codebase search, not built-in |
| Tabnine | $12/mo | Privacy-first, runs locally in JetBrains |
FAQ
Does JetBrains AI Assistant work in all JetBrains IDEs? Yes. One AI Pro subscription covers all JetBrains IDEs — IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, DataGrip, and others. If you use multiple JetBrains IDEs, the All Products + AI bundle is more cost-effective than buying IDEs and AI separately.
Can I use JetBrains AI alongside GitHub Copilot? Yes, both can be installed simultaneously. Some developers use Copilot for autocomplete and JetBrains AI for chat and code actions. There is overlap, so most users find one sufficient.
Is there a free tier? JetBrains includes a limited AI free tier in its IDEs. It provides a reduced number of AI completions and chat interactions. Most active developers will find it insufficient and need the Pro plan.
