How to Use JetBrains Junie in 2026: Step-by-Step Guide
JetBrains' autonomous coding agent — takes a task description and independently plans, edits, and tests code changes across a project inside JetBrains IDEs.
Junie is JetBrains' autonomous coding agent, distinct from the more suggestion-based JetBrains AI Assistant — it takes on a described task and works through it with less step-by-step supervision.
Core Capabilities
Autonomous Multi-File Changes Given a task ("add pagination to this endpoint"), plans the change, edits across relevant files, and runs the project's existing tests to check its own work.
Deep IDE Integration Operates inside JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, etc.), using the IDE's own indexing and code understanding rather than a bolted-on plugin.
Review Before Commit Surfaces a diff of all agent changes for review before anything is committed, keeping a human in the loop on the final decision.
Positioning
JetBrains' answer to Devin, Cursor's agent mode, and GitHub Copilot Workspace — aimed at JetBrains' existing professional developer base rather than a new IDE.
Pricing
Included with a JetBrains IDE subscription; usage-based limits on agent runs.
What You'll Need

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 Junie what format you want by including an example in your prompt.
- Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.
Common Use Cases

- 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."
