Open-source React chat UI building blocks — ship an LLM interface in hours, not weeks.
Tune the chat interface to match your product with configurable components and theming options rather than fighting a locked-down widget.
Handle file uploads, embedded content and markdown formatting out of the box, so conversations can carry richer information than plain text.
Switch between different AI models, or mix several models inside the same interface to serve different tasks.
An intuitive but flexible API designed so you can compose custom chat experiences without disproportionate glue code.
A drop-in React Markdown renderer built for streaming AI output
Built-in Tailwind typography for headings, lists and code blocks, plus GitHub Flavored Markdown for tables, task lists, strikethrough and autolinks.
Caret indicators show that content is still generating, unterminated blocks are parsed rather than broken, and transitions are animated for smoother output.
Shiki-powered syntax highlighting with copy and download buttons, automatic language detection and optional line numbers.
LaTeX math through KaTeX, interactive Mermaid diagrams with fullscreen viewing, and CJK support so ideographic punctuation renders correctly.
