Elise UI

Introduction

Elise UI is composable UI for AI agents. The components read AG-UI events and show what the agent is doing: starting a run, calling a tool, writing an answer, or failing. Not a generic spinner.

Works with any AG-UI stream

Any agent that sends AG-UI events works, including TanStack AI, whose chat streams are AG-UI events.

Built from parts

Each component is a root and a few small parts. Put the parts in any order, leave some out, and add your own elements between them. The parts have no colors, so they take your design.

Components

  • Loading — one line that follows the latest event.
  • Loading Stacked — one row for each step: tool calls, messages, thinking.
