Log in
To start working with AI Assistant, you need to log in first.
Click the AI Assistant icon on the right toolbar to open AI Assistant.
Click Log in to JetBrains AI service and follow the steps in the browser.
You can change your account on the Tools | AI Assistant page of the IDE settings Control+Alt+S.
Chat with AI
Use the AI Assistant tool window to have a conversation with the LLM (Large Language Model), ask questions about programming-related topics, or iterate on a task. The AI Assistant takes into consideration the language and technologies used in your project.
Click the AI Assistant icon on the right toolbar to open AI Assistant.
In the input field, type your question and press Enter to submit your query.
AI Assistant keeps the chats during one IDE session. You can find the saved chats in the All Chats list. 
Names of the chats are generated automatically and contain the summary of the initial query.
Use prompts to explain and refactor your code
Use pre-written prompts to explain code, find potential problems, and refactor your code. GoLand provides project-specific context, such as the languages and technologies used in your project.
You can also define your own custom prompts and add them to the AI Actions menu.
Explain code
Select a code fragment and right-click it to open the context menu.
Alternatively, select a code fragment and press Alt+Enter.
Select AI actions and then Explain code.
The AI Assistant tool window will open to provide you with an explanation.
Explain regex, cron expressions, and SQL queries
AI Assistant can explain regular expressions, SQL queries, cron expressions, and other injected fragments.
Select a code fragment and right-click it to open the context menu.
Alternatively, select a code fragment and press Alt+Enter.
Select AI actions and then Explain fragment.
AI Assistant automatically detects the type of injected fragment, so the context menu option for regular expressions will be Explain RegExp fragment and likewise for other fragments.
AI Assistant will analyze and explain the fragment.
Suggest refactoring
Select a code fragment and right-click it to open the context menu.
Alternatively, select a code fragment and press Alt+Enter.
Select AI actions and then Suggest refactoring.
The AI chat will open to offer you refactoring suggestions.
If you like the result, click
in the field with the refactored code to put the AI-generated code into the editor and replace the originally selected code fragment.
Find potential problems
Select a code fragment and right-click it to open the context menu.
Alternatively, select a code fragment and press Alt+Enter.
Select AI actions and then Find potential problems.
The AI chat will open to show the potential issues you may want to look into.
Add your own prompts to prompts library
You can add your own prompts to the prompts library and use them via AI Actions menu.
Press Control+Alt+S to open the IDE settings and then select .
Click
to create a new prompt. In the text field, write the prompt. If needed, use the following variables:
$SELECTION: a Markdown-formatted code block with current code selection and language name.$SELECTION_RAW: selected code fragment.$SELECTION_LANG: the language of the currently selected code fragment.$PRODUCT_NAME: the name of the product that is currently launched, for example, GoLand.
In the advanced options, edit the new prompt name.
Select the first checkbox if you want AI Assistant to wait for you to make additional input in the chat after invoking the prompt.
Keep the second checkbox if you want your new prompt to be listed in the AI Actions menu.
Click Apply.
After you created a prompt, you can always edit or delete it.

How we handle your code and data
When you use AI features, GoLand 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, GoLand 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 controlls detailed data collection can be found in the IDE Settings under .
For more detailed information on our data collection policies, please refer to Data Collection and Use Policy.
