In-App Preview
Artifact Panel
Edit, preview, and run files without leaving the conversation.
Marnie includes a Claude-like side-by-side Artifact Panel for creating, viewing, editing, and previewing files in the browser while maintaining active conversations. HTML runs in a sandboxed iframe, Markdown renders GitHub-flavored, math equations render via KaTeX, and diagrams render via Mermaid.js.
