How to Use JetBrains AI Assistant in 2026: Step-by-Step Guide
JetBrains AI Assistant is an AI coding companion embedded natively across all JetBrains IDEs — IntelliJ IDEA, PyCharm, WebStorm, GoLand, and others. It provides AI chat, inline code completion, refactoring suggestions, and test generation that understands the full context of your project through deep IDE integration, with support for multiple AI providers.
JetBrains AI Assistant (jetbrains.com/ai) is the AI layer built directly into the JetBrains IDE family. Unlike standalone AI coding tools, it operates inside the same IDE environment where developers write code every day — with access to the project structure, type information, documentation, and code context that an external tool can't see.
IDE-native advantages
Because AI Assistant lives inside the IDE, it can reference the actual code in your project when you ask questions — not just the file you have open, but your full project structure, dependencies, and the semantic model the IDE maintains. When you ask 'How does this function interact with the database layer?', it can trace through multiple files using the IDE's code understanding rather than just text pattern matching.
Inline completions appear in the editor as you type, similar to GitHub Copilot — but with awareness of the IDE's type system. PyCharm's AI Assistant understands Python types; IntelliJ's understands Java generics. This reduces the frequency of completions that look syntactically correct but are semantically wrong.
AI chat
The AI chat panel allows free-form questions about code in the context of the current project. Common uses: explaining unfamiliar code, generating test cases for a function, suggesting refactoring approaches, debugging error messages, and generating code based on natural language descriptions.
Multi-model support
JetBrains AI Assistant supports multiple AI backends — JetBrains' own models, OpenAI GPT, and Anthropic Claude — letting teams choose which model to use based on capability, cost, and data residency requirements.
Who uses it
JetBrains IDEs are particularly popular in enterprise Java, Kotlin, Python, and Go development. AI Assistant is used by professional developers who already use a JetBrains IDE and want AI assistance without switching to a different editor.
Frequently Asked Questions
How does JetBrains AI Assistant compare to GitHub Copilot? Both offer inline completions and AI chat. AI Assistant's advantage is deeper IDE integration — it understands your project's type system and structure. GitHub Copilot has broader adoption and is editor-agnostic. Is AI Assistant included with a JetBrains IDE license? No — it's a separate subscription at approximately $10/month, or included with the All Products Pack.
What You'll Need
- A JetBrains AI Assistant account (starting from $10/month)
- A modern web browser or the JetBrains AI Assistant app
- Payment method for paid features
Getting Started
Create Your Account
Visit https://www.jetbrains.com/ai/ and sign up for a paid account. You'll need an email address to register.
Start Your First Conversation
Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. JetBrains AI Assistant supports text, code — start with a simple text prompt to get familiar.
Natural Language Chat
Type your question or task in natural language. JetBrains AI Assistant excels at understanding context and providing helpful, detailed responses.
Code Assistance
For coding help, paste your code or describe your problem: 'Here's my function, why isn't it working?' You can ask for explanations, debugging, or new code generation.
Pro Tips
- Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
- Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
- Use examples: Show JetBrains AI Assistant what format you want by including an example in your prompt.
- Share context: When asking for code help, include your programming language, framework, and what you're trying to accomplish.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
Common Use Cases
Programming & Code
AI assistants focused on writing, debugging, and explaining code across programming languages.

- Responses seem generic or unhelpful
- Add more context to your prompt. Specify the audience, tone, length, and format you need. Try starting over with a clearer description of your goal.
- The tool isn't responding or is slow
- AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
- Output is too long or too short
- Explicitly specify the length: "in 100 words," "as a brief summary," or "in detail with examples."
