Use AI prompts to explain and refactor your code

Last modified: 21 February 2025

This functionality relies on the AI Assistant plugin that requires an additional license.

For more information about licensing and enabling AI Assistant, refer to JetBrains AI Service licensing and Enable AI Assistant plugin.

Use pre-written prompts to explain code, refactor, and find problems in 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, or modify the built-in prompts.
