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.

Preview Tailwind CSS and React output inside ChatGPT as you build
Renders HTML that uses Tailwind utility classes in a preview pane beside the ChatGPT conversation, so styles appear correctly without leaving the chat.
Interprets React output, including createRoot render patterns, and shows the resulting UI in the same live preview area.
Bundles curated prompts for Tailwind CSS page and component generation plus React component design, cutting the prompt-writing work on repeat tasks.
Regenerating a response refreshes the preview in place, keeping the design-prompt-redesign loop entirely within ChatGPT.
