Overview
Ink is ARK's block-based documents workspace. Text, tables, code, embeds, and real-time collaboration — running on your Supabase, with markdown in and markdown out.
What Ink does
Ink is an editor-first wiki. If you've used Notion, you'll feel at home within seconds.
- Block editor — slash commands, drag-and-drop, every block typed and structured.
- Spaces — separate areas per team with independent permissions, templates, and index pages.
- Real-time collaboration — live cursors, presence, @-mentions, inline comments.
- Tags — freeform labels that cut across spaces for easy discovery.
- Conversations & threads — per-page discussions that don't clutter the main content.
- Sharing — internal, external (signed links), or fully public with a custom domain.

Feature highlights
Block editor. Every unit of content is a block — paragraph, heading, list item, callout, code block, toggle, image, embed. Blocks are draggable; slash commands insert them inline.
Spaces. Top-level containers. One space per team is typical ("Engineering", "Design", "Ops"). Each has its own permissions, member roster, templates, and index page.
Real-time. Open the same page in two tabs and watch changes propagate instantly. Avatars render alongside the cursors of every co-editor.
Versioning. Every page has a full history of revisions. Restore any prior state. Diff any two revisions.
Import/export. Markdown round-trips cleanly. HTML export for sharing with people outside your workspace. Notion import available as a paid add-on for migrating from existing workspaces.
Publishing. Any page or space can be published as a public site under your own custom subdomain. Pair with the ARK docs template for a full documentation site.
