Kotlin Notebook Meets IntelliJ Platform
summary
Kotlin Notebook opens inside IntelliJ IDEA 2025.x and runs Kotlin cells either in a separate JVM or run in IDE process so code can access the real IntelliJ Platform jars and a live Project instance. It fetches Maven/Gradle deps and line-magic libs (Candy for charts), renders Compose-style UI and images, can register actions and load bundled plugins, and even trigger UI effects (example: shake IDE). Expect to restart kernel after code change; execution order and disposables matter and EAP builds may be unstable.
