Harnessing the Power of AI in IntelliJ IDEA by Anton Arhipov, JetBrains - 26 March, 2025

AI-powered tools are transforming software development, but how much control do they give developers over their workflow? Is it a productivity booster or a placebo? Anton will do his best to explain in this session. In this session, we’ll explore how AI assistance in IntelliJ IDEA — through both JetBrains AI Assistant and the new Junie coding agent—supports developers in writing, understanding, and improving code. Anton will demonstrate the capabilities of the AI-assisted coding in IntelliJ IDEA by exercising the prompts for various development workflows: explore legacy code, improve existing code via refactoring and tests, learn new technology, or implement new functionality in your application.
