For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A floating right Sidebar that pushes the page, where selecting a reply sentence opens a quote pill and arrow keys walk a suggestion list

When to use

  • A full page assistant chat, new chat welcome screen or 2 model comparison inside an AI product
  • A copilot docked beside the page it works on, or opened from a launcher in the page corner
  • Answers that show the work behind them: sources read, tool steps, plans to approve and run cost

When not to use

  • A task workspace where the assistant panel sits beside lists and color tags: use the To-Do AI Assistant block
  • A docs support sidebar that ticks off each knowledge base article it reads: use the Docs Support Assistant block
  • The product layout around the chat: a sidebar of threads, workspaces and account menus: use the App Shell blocks
  • A plain overlay chat panel opened from a button, with suggestion chips and a composer: use the Sheet blocks
  • A highlighted snippet with a filename header and copy button, outside any conversation: use the Code Block component

Agent notes

  • PageBody is Skeleton placeholder rows; put your page inside SidebarInset and keep SidebarProvider wrapping it and ChatPanel
  • Replace THREADS, SOURCES, SUGGESTIONS and REPLY_LIBRARY in data.ts; Attach offers only the 2 SOURCES documents, not a file picker
  • send hands draftReply the prompt and quote only, so modelId and modeId never shape the canned reply
  • Each AiChat root sizes itself to the viewport with h-svh, or min-h-svh in ai-chat-5; give it your layout's height inside an app shell
  • Every reply is canned content from the block's data file, played back on setTimeout and setInterval timers; stream your model's output there instead

Shadcn Quote Reply Sidebar Block

Floating right chat sidebar that pushes the page and replies to a quoted sentence. Part of the ReUI Shadcn AI & Agents AI Chat blocks collection.

Reveal and hide a floating AI panel beside any page: select a sentence in an answer to reply to that line, a keyboard suggestion palette, a workspace Personalize toggle, thread switcher, model and mode picker, and a designed thinking indicator.

It is composed from Attachment, Avatar, Badge, Bubble, Button, Card, Dropdown Menu, Empty, and more, so every part of it is a primitive you can restyle with your own design tokens.

What You Can Build With the Quote Reply Sidebar Block

  • Install it with the ReUI registry command in the toolbar above, then swap the placeholder content, data wiring, and business logic for your own.
  • Compare it across all eight ReUI styles and both the Base UI and Radix bases in the customizer before committing to one direction.
  • Combine it with the other Shadcn AI & Agents AI Chat blocks to assemble a full screen instead of a single section.
