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 release notes draft beside a collapsible assistant dock, where Insert writes the drafted section into the page and Undo takes it out

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

  • An assistant overlay with no document beside it to write a reply into: use the AI Model Chat block
  • An agent that runs a multi step plan with approvals inside its replies: use the Agentic Task Panel 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 THREADS, CONTEXT_SOURCES, STARTERS and COLLABORATORS in data.ts; Share copies the fixed DOC_SHARE_URL
  • handleToggleDraft only sets draft state, so Insert and Undo never save; ReleaseDoc shows skeletons for every section but DRAFT_SECTION_ID
  • Attached CONTEXT_SOURCES chips clear on send and never reach onSend, which receives only the typed text
  • 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 Docked Assistant Block

Docked AI assistant chat panel beside a page with insert into draft. Part of the ReUI Shadcn AI & Agents AI Chat blocks collection.

Sticky right side AI copilot beside a page: streaming thread, grouped Message bubbles, markdown code block, model picker, quick replies, and an Insert action that writes the reply into the document. Sheet on mobile.

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

What You Can Build With the Docked Assistant 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.
