Your Java AI Agent at Home – Ronald Dehuysser | IntelliJ IDEA Tech Talks

In the third episode of IntelliJ IDEA Tech Talks, I talk to Ronald Dehuysser – creator of JobRunr, about the ClawRunr project. Ronald shows us how to use ClawRunr as a personal AI assistant and shares stories of how he uses it himself.

Description

What if you had a personal assistant who could check your emails, schedule tasks, prepare a legal dossier, and send a thank-you note, all from your phone while you’re on a ski slope?

ClawRunr is an open-source Java-based personal assistant that combines AI with background job scheduling. You chat with it in natural language, it figures out what to do, and Spring AI and JobRunr handle the rest.

Ronald Dehuysser, the creator of JobRunr, walks us through setting up ClawRunr, from choosing your LLM provider and connecting MCP servers to scheduling recurring tasks using live demos. He also shares what he learned taking it from a vibe-coded idea to an extensible demo app: why solid architecture matters for agent-style development, and why handing off as much as possible to the AI beats coding everything yourself.
