Write with ease

A rich editor — or Markdown, your choice

Format with a familiar toolbar or write raw Markdown; both edit the same document and stay in sync. Paste screenshots straight into a step, lay out tables and color panels, and run one click of AI proofreading before you publish.

What you get

  • Tables, color panels, heading highlights, and email-safe fonts
  • Paste screenshots in place — drag to size, side-by-side layouts, zoom, alt text
  • Rich blocks, fully editable in the WYSIWYG editor: callouts, tabs, and accordions as live boxes; Mermaid & PlantUML diagrams with live preview while you type; video & website embed cards; click-to-tick checklists; decision-tree guides; filterable tables — all one click from the toolbar
  • A toolbar that stays with you as you scroll long documents
  • AI proofread with apply-or-dismiss suggestions that keep your meaning

Markdown under the hood

Documents are stored as portable Markdown — export them anytime, edit them anywhere, no lock-in.

Images that behave

Uploads live with the document, render sized and zoomable, and print cleanly.

Every edit versioned

Each save snapshots a version with its author — browse and preview any past revision.

Frequently asked

Do I have to know Markdown?

No. The rich-text toolbar covers everything — bold, headings, tables, panels, lists, links, images. Markdown mode is there for those who prefer it, and both stay in sync.

What does AI proofread change?

Grammar, spelling, and clarity — presented as individual suggestions you apply or dismiss. It preserves meaning and formatting, and it needs an Anthropic API key configured by an admin.
