JetBrains AI Assistant FAQ (2026): Pricing, Models, and Common Questions

Last updated: May 2026

What is JetBrains AI Assistant?

JetBrains AI Assistant is the built-in AI feature set across all JetBrains IDEs — IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider, CLion, and others. It provides code completions, AI chat, code generation, test creation, documentation, and autonomous workflow agents — all without leaving the JetBrains IDE you already use.

Is JetBrains AI Assistant free?

Yes, there is a free tier with limited usage. Full access is included with a JetBrains IDE subscription or All Products Pack. JetBrains bundles AI Assistant into its existing subscription model rather than charging separately — making it effectively free for developers already paying for a JetBrains IDE license.

How much does JetBrains AI Assistant cost?

AI Assistant comes with JetBrains IDE subscriptions:

For developers already on a JetBrains subscription, AI Assistant adds no incremental cost. This makes it considerably cheaper than adding Copilot ($10/month) or Cursor ($20/month) as a separate tool.

Which AI models does JetBrains AI Assistant use?

JetBrains AI Assistant uses a rotating set of frontier models including Claude 4.0 Sonnet, Claude 4.5 Haiku, Gemini 2.5/3.0, Azure GPT-5, and Qwen 2.5. You can select which model to use for different tasks. The 30% average code autocomplete rate reported by JetBrains puts it among the more accurate autocomplete tools available.

What can JetBrains AI Assistant do beyond autocomplete?

• AI chat — codebase-aware Q&A, code explanation, refactoring suggestions
• Image to code — generates code from UI mockup screenshots
• Test generation — creates unit tests for selected functions
• Documentation — generates KDoc/JavaDoc/docstrings automatically
• Code review agents — autonomous review with organizational standards enforcement
• Jira implementation — takes a Jira ticket and implements the described change
• Coaching — explains what it did and why, with learning-oriented explanations

How does JetBrains AI Assistant compare to GitHub Copilot for JetBrains users?

Both run in JetBrains IDEs. For a developer already paying for a JetBrains subscription, AI Assistant is the obvious default — no additional cost. GitHub Copilot at $10/month adds model flexibility (Claude, GPT-4o, Gemini in a single subscription) but at an additional price on top of your JetBrains license.

The practical rule: if you are a JetBrains subscriber, start with AI Assistant. Add Copilot or a BYOK tool like Continue only if AI Assistant's models or features are insufficient for your workflow.

Does JetBrains AI Assistant work with local models?

Limited support. JetBrains has added some local model options in recent releases, but the integration is less mature than tools like Continue.dev or Cline, which were built around BYOK from the start. For full local model flexibility in JetBrains, Continue.dev with Ollama is the more capable setup.

Does JetBrains AI Assistant send my code to external servers?

Yes. Code context is sent to JetBrains' AI backend, which routes to the selected model provider. JetBrains states that code is not used to train models. For teams with strict data residency requirements, check JetBrains' current data processing agreements — they offer EU data residency options for Enterprise customers.

Is JetBrains AI Assistant worth it compared to switching to Cursor?

If you are deeply embedded in JetBrains workflows — project structure, run configurations, debugger, database tools — the switching cost to Cursor is high and often not worth it. JetBrains AI Assistant gives you capable AI inside the environment you already know. Cursor is a VS Code fork and does not replicate JetBrains' deep language-specific tooling for Java, Kotlin, or C#. Stay on JetBrains with AI Assistant unless you have a specific reason to switch.
