What JetBrains Junie does
Junie is JetBrains' IDE-native coding agent for exploring projects, editing files, running commands and tests, and iterating on complex tasks.
Junie brings agentic coding into the JetBrains environment where many developers already navigate, refactor, run, and debug software. It can interpret a task, plan a multi-step approach, edit multiple files, invoke commands, and use test results to iterate. Context is controllable: the active file and selection can be attached automatically, while broader files are added explicitly. Users can also choose a model and reasoning level, which lets them trade speed, credit consumption, and deeper analysis according to task complexity.
Confirmation boundaries deserve as much attention as model quality. Junie normally asks before potentially sensitive actions, while Brave Mode permits commands and modifications without approval; JetBrains explicitly warns of data-loss and security risk. Teams should keep Brave Mode off for unfamiliar repositories, inspect shell commands, use version control, sandbox services, and prevent access to production credentials. Agent-generated refactors can compile while changing behavior, tests can be shallow, and dependency edits can introduce license or supply-chain risk. The IDE agent does not remove peer review, trusted CI, or threat modeling.
AI Pro costs $100 per user annually and includes 10 AI Credits per 30 days with limited Junie experimentation. AI Ultimate costs $300 annually, includes 35 credits, and is recommended for regular agent use; AI Enterprise is $720 annually and advertises daily Junie use plus enterprise controls. Top-ups make workload cost variable. JetBrains says requests and relevant code are sent to an LLM provider. Detailed code-related collection, which can include full prompts and code and may support model training, is opt-in and disabled by default. Administrators should verify this setting, provider routes, retention, project exclusions, and enterprise terms.
How JetBrains Junie works
Junie combines a prompt with explicitly attached files and optional active-editor context, selects a supported model and reasoning level, then plans edits and uses IDE tools or commands. By default sensitive actions request confirmation; Brave Mode can remove that barrier, so developers must inspect the diff and tests.
Attach only the required project material
Junie receives the prompt, explicitly attached files, and optional active-editor file and selection. Developers state architecture, commands, expected behavior, and exclusions while keeping credentials outside model context.
Choose a model and approve the plan
The selected model and reasoning level shape the agent's approach, latency, and credit use. The developer reviews its multi-step plan and corrects mistaken scope before file or command execution.
Edit and run tools with confirmations
Junie changes project files and invokes IDE or shell tools, using results to iterate. Confirmation prompts protect sensitive actions; Brave Mode removes that control and should remain off for unfamiliar or high-risk work.
Audit the complete local change
Review the diff, dependencies, commands, tests, and runtime behavior, then run trusted CI and peer review. Check credit usage and data-sharing settings before using the workflow on broader proprietary code.
How to set up JetBrains Junie
Verify IDE and subscription eligibility
Confirm the target JetBrains IDE, plugin, account, plan, and credit allowance support Junie, then update the IDE and test in a disposable branch.
Review data-sharing controls
Keep detailed code-related data collection disabled unless explicitly approved, identify model providers and retention terms, and exclude secrets, credentials, and regulated source material.
Constrain automatic context
Inspect whether the active file and selection are attached, add only the files necessary for the task, and state architectural rules, commands, and forbidden changes in the prompt.
Keep command confirmation enabled
Leave Brave Mode off for initial and high-risk work, examine every proposed command and file operation, and run services against local or disposable resources.
Validate the completed change
Review the entire diff and dependency graph, run trusted tests and security checks independently, inspect credit usage, and require normal peer approval before merge.
JetBrains Junie FAQs
Is JetBrains Junie free?
Junie access is tied to JetBrains AI subscriptions and credits. AI Pro provides limited experimentation; regular agent use is positioned with AI Ultimate or Enterprise.
How much does Junie cost?
AI Pro is $100 per user annually, AI Ultimate is $300, and AI Enterprise is $720. Included credits differ, and optional top-ups can increase actual cost.
What is Junie Brave Mode?
Brave Mode lets Junie execute commands or modify files without asking for individual confirmation. JetBrains warns this can lead to data loss or security problems.
Does JetBrains collect code from Junie?
Code context required for a request is sent to the selected LLM route. Separate detailed code-related collection is opt-in, disabled by default, and may be used for product improvement and model training.
Can Junie replace peer review?
No. Engineers must verify commands, diffs, dependencies, tests, security, and runtime behavior. IDE integration and successful compilation do not prove that a change meets product intent.
