IntelliJ IDEA 2024.1 Help

AI Assistant

AI Assistant provides AI-powered features for software development. It can explain code, answer questions about code fragments, provide code suggestions, generate documentation, commit messages, and much more.

The AI Assistant plugin is not bundled and is not enabled in IntelliJ IDEA by default.

AI Assistant will not be active and will not have access to your code unless you install the plugin, acquire a JetBrains AI Service license and give your explicit consent to JetBrains AI Terms of Service and JetBrains AI Acceptable Use Policy while installing the plugin.

JetBrains AI Service licensing

The AI Assistant plugin is powered by the JetBrains AI Service. This service transparently connects you, as a product user, to different large language models (LLMs) and enables specific AI-powered features within many JetBrains products.

If you have an active IntelliJ IDEA Ultimate subscription, you can acquire the AI Assistant license at the JetBrains AI Service website. Before acquiring the license, you can sign up for a limited trial (available only for users with commercial and personal paid IntelliJ IDEA licenses). The AI Assistant license or your free trial will be linked to your JetBrains Account.

For more information about licensing plans and features' availability, refer to the FAQ at JetBrains AI Service website.

If you need any help regarding your license, you can contact our support team.

Use AI Assistant features

Here is how you can work with AI Assistant:

How we handle your code and data

When you use AI features, IntelliJ IDEA needs to send your requests and pieces of your code to the LLM (Large Language Model) provider. Besides the prompts you type, it may send additional details, such as file types, frameworks used, and any other information that may be necessary for providing context to the LLM.

In addition, IntelliJ IDEA builds with the AI Assistant plugin perform opt-in collection of detailed data about the usage of AI features, including the full communication between you and the LLM (both text and code fragments). This data is kept strictly confidential and is used by JetBrains for product improvement purposes only. It is never shared with any external parties, and it will not be used for training any ML models that generate code or text, or revealed in any form to any other users. The option that controls detailed data collection can be found in the IDE Settings under Tools | AI Assistant | Data Sharing | Allow detailed data collection and is disabled by default.

For more information about our data collection policies, refer to Data Collection and Use Policy.
