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 greeting over Start rows that fill the composer and attach a source, with Instant, Extended or Deep effort and an in thread Questionnaire

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

  • Starter prompts sorted into Create, Explore, Code and Learn with a context meter: use the Copilot Shell block
  • Connected work apps toggled in the composer to decide what an answer reads: use the Connected Apps Chat 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

  • Replace STARTERS, THREADS, CONTEXT_SOURCES and GREETING in data.tsx; the stats under GREETING are fixed strings, not live counts
  • draftReply matches on prompt text alone: attached contextIds never reach it, and the effort pick delays the same canned reply by its planMs
  • planFromScope turns Questionnaire answers into a fixed plan template, and attachment downloads in replies only fire a toast
  • 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 Prompt Starter Welcome Block

AI chat welcome screen with prompt starters and a docked composer. Part of the ReUI Shadcn AI & Agents AI Chat blocks collection.

AI assistant welcome screen and zero state: an Empty greeting with live workspace stats, one rail of start and resume rows that fill the composer and attach context, an InputGroup composer with Attachment chips, and a streaming reply with Stop. A new chat page with prompt suggestions and recent conversations.

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

What You Can Build With the Prompt Starter Welcome 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.
