About AI Sidebar

AI Sidebar is the navigation an AI app needs: search, a new chat button, starred and recent chats, projects that open like folders, rename on double click, and a spring collapse to an icon rail.

AI Sidebar is an AI interface component for React 19, styled with Tailwind CSS 4 and animated with Motion. It drops into Next.js, Vite, Remix or Astro through the shadcn CLI as a single file you own.

When to use AI Sidebar

  • Chat and assistant apps.
  • AI writing and coding tools.
  • Internal copilots.
  • Any app organised into threads and projects.

How it works

Every action is a labelled button and project folders expose aria-expanded. Folders open on height springs, rename is an inline input that commits on Enter, and the collapsed rail keeps every chat reachable with a title and label.

Streaming and status changes go through live regions, every action is a labelled button that works from the keyboard, and decorative motion stops for people who prefer reduced motion. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.

Customizing AI Sidebar

Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.

The Customize panel next to the preview lets you change defaultCollapsed live, and the Code tab updates to match, so the snippet you copy already carries your values.

  • projects.
  • recent ({ id; title; starred? }[]).
  • activeId (string).
  • defaultCollapsed (boolean, default false).

Goes well with AI Sidebar

These ai pieces share its tokens and motion language, so they sit together on one page without clashing.

  • Typing Indicator: A React typing indicator: a bubble with rippling dots that tells screen readers who is typing
  • Thinking Orb: A React AI thinking orb with nine motions for nine kinds of busy
  • AI Prompt Input: An animated React AI chat input: growing field, attachments, model picker and a stop button
  • Voice Input: A React voice input: the mic expands into a live waveform with a timer and cancel
  • Message Scroller: A React chat viewport that follows streaming text and lets go when you scroll up
