Ask HN: How to deal with UI within the agentic loop

#1

Post by mattsadowsky » Wed, Jun 17, 2026, 8:48 PM UTC

I am planning to the module in may SaaS to allow user to chat about its data, features, modules that he have in his workspace with LLM Agent.

What approach should I use to render UI within the chat? any recommendations?

I know two approaches. One is free-form rendering, like Anthropic's Artifacts. The other is to designate a category of tools whose output gets caught by the frontend and rendered in the chat using the corresponding components. I used the second one in several projects.

Ok, but what tech you are using second one approach? any open source, specific tech?

I built it by myself. If you want, I can share the code with you.

No, it is fine. Could you tell me only what langage you use to generate UI? HTML, JSON, MD? I what output you expect from AI Agent to generate UI component?
