About
About Assistant UI
This comprehensive UI toolkit provides fully composable primitives built on Radix UI with built-in features like message streaming, automatic scrolling, typing indicators, and complete accessibility support through WAI-ARIA compliance. The library supports integration with major AI providers including OpenAI, Anthropic Claude, Google Gemini, and any backend compatible with Vercel AI SDK, offering maximum flexibility for AI application development. With enterprise-ready components, developers get features like markdown rendering, code syntax highlighting, file attachments, voice input support, conversation threading, and customizable themes that work seamlessly with shadcn/ui styling.
The composable architecture allows fine-grained control over every aspect of the chat interface, from message bubbles and input areas to suggestion chips and action buttons, while maintaining excellent performance and developer experience. Perfect for building AI assistants, customer support chatbots, documentation helpers, or any conversational AI application, Assistant UI eliminates weeks of UI development by providing battle-tested components that handle the complexity of real-time streaming, state management, and user interactions, allowing teams to focus on AI logic rather than interface implementation.

FAQ
Frequently asked questions
Everything you need to know before you ship with Assistant UI.
Assistant UI is an open-source TypeScript/React library designed for rapidly building production-grade AI chat interfaces with ChatGPT-like experiences. It is an open source template in the shadcn.io collection of 215.
Assistant UI is made by Assistant ui, an independent developer; shadcn.io lists it but did not make it. Assistant ui has 1 template in the collection, and the author's page lists them.
The listing tags Assistant UI with Radix UI and UI Kits & Component Libraries. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.
Yes. The Assistant UI page embeds its live demo from assistant-ui.com, and links to it so you can open the real deployment before you clone.
The Assistant UI listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.
Clone the repository (git clone https://github.com/assistant-ui/assistant-ui), then follow the README. The Assistant UI page shows the usual steps and a terminal block with the commands to copy.
Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Assistant UI repository says which package manager and environment variables it needs.
No. Assistant UI is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.
Follow the deployment notes in the Assistant UI README: the right host depends on its framework and any services it needs. The page's categories show what it is built for.
The Assistant UI listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/assistant-ui/assistant-ui), and ask the author if there isn't one.
That depends on Assistant UI's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.
Attribution follows Assistant UI's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.
No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. Assistant UI is the author's project, under the terms in its repository.
Assistant ui supports Assistant UI, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.
Yes. Once you clone it, Assistant UI is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.
Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Assistant UI uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.
Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up Assistant UI for you. Your files stay on your machine.
The collection has 19 other open source UI Kits & Component Libraries templates like Assistant UI, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/ui-kits-and-component-libraries.
Assistant ui has no other templates in the collection.
Yes. The 14 premium templates (Solaris, Reframe Labs, Spherule and Max and more) are built by shadcn.io and come with every Pro plan, if you want maintained code with a design file.
