Install AI Assistant in a JetBrains IDE
The AI Assistant plugin is not bundled and is not enabled in JetBrains IDEs by default[1].
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.
Install the AI Assistant plugin and activate your license
You can install AI Assistant with a single click from 
JetBrains AI widget or AI Chat tool window. Junie, the coding agent, will also be installed if it is available in your IDE.
After installation, AI Assistant checks your license status:
If you already have an active AI Assistant license, it will be automatically verified and activated.
If your previous AI Assistant license has expired, you will receive the AI Free license tier with a possibility to upgrade to a different tier at any time.
If you are an owner of All Products Pack or dotUltimate, you will receive the AI Pro license tier.
If you are a new user and do not have an AI Assistant license yet, you are eligible for a 30-day trial of AI Pro license tier. The free trial will be linked to your JetBrains Account and activated automatically.
To start the installation:
Click the
JetBrains AI widget located in the toolbar in the window header.
Click Let's go. The plugin installation and license activation will be performed automatically.
Click AI Chat on the right toolbar to open the AI Assistant chat tool window.
Click Install Plugin. The plugin installation and license activation will be performed automatically.
There is also an option to manually install the plugin from the JetBrains Marketplace:
Open and type AI Assistant in the search field.
Click Install.
Once the plugin is installed and the license is successfully activated, you can start using AI Assistant.
For more information about enabling and disabling AI Assistant on a company level, refer to How to enable AI Assistant for companies.
Check license details
If you want to check the details of your license, do the following:
In the AI Chat tool window, click the
Options button. 
Select the Manage License option from the list.
This opens a License pane where you can review the license details:
If you have multiple licenses, you can choose the one you want to use by selecting it from the list and clicking Activate.
To refresh the list of licenses, click Refresh license list.
Manage plugin settings
Once the plugin is installed, you can control its key settings in the JetBrains AI widget.
Using this widget, you can:
