/document writes long-form documents into the Document panel — a rich-text editor that opens beside your chat. Use it for essays, reports, proposals, letters, and anything you want to refine and export.
Cost: Billed on output tokens at your selected chat model’s rate — from 3 credits on the default model. Longer documents and pricier models cost more.
Type /document followed by what you want written:
/document Write a professional cover letter for a software engineer position

/document Create an executive summary for a Q3 sales report
/document Draft a blog post about sustainable living tips
The document streams into the panel live — you watch it being written.
When you use /document, Krater opens an editor panel next to the conversation where you can:
.md, .txt, .html, or .docxThe panel is resizable on desktop and full-screen on mobile.
