Where your team's documents come together.
A familiar block editor, spaces for every team, and real-time collaboration — all running on your own database. Notion-style ergonomics without the lock-in.
Built for the way your team actually writes.
Real teams don't write docs to be pretty — they write to think out loud, capture decisions, and bring new people up to speed. Ink stays out of the way and lets the writing happen.
A block editor you'd actually pick.
Text, headings, lists, toggles, callouts, code, tables, embeds. Keyboard-first, slash commands, and every block is draggable. Familiar to anyone who's used Notion — without the per-seat invoice.
- Slash commands and keyboard-first flow
- Drag-and-drop block reordering
- Code blocks with syntax highlighting
- Inline math (KaTeX) and embeds
Spaces for every team.
Organize docs into spaces — engineering, design, ops, clients. Each space has its own permissions, templates, and index page. Nest pages as deep as your team needs.
- Independent spaces with their own permissions
- Nested pages and subpages
- Page templates per space
- Favorites, recents, and full-text search
Live cursors, inline comments.
Multiple cursors, inline comments, @-mentions, and presence. Everyone stays on the same page — literally — and the comment thread links right back to the message in Comms.
- Real-time multi-cursor editing
- Inline comments and @-mentions
- Version history per page
- Comms integration — chat about a doc inline
Markdown in, markdown out.
Every block is stored as structured JSON in your Postgres. Paste markdown, export markdown, query it, back it up, feed it to your own AI. No vendor export needed — you already have the data.
- Markdown import and export
- HTML and PDF export
- Public publishing with custom domains
- Every block is a queryable database row
A complete feature set, grouped by what you're trying to do.

Questions, answered.
Yes. Spaces + nested pages + search + templates give you a proper internal wiki out of the box.
Ink loads pages incrementally by block, so long docs stay smooth. Backends are just Postgres rows — there's no artificial size limit.
Yes. Any space or page can be published under a custom subdomain with SEO metadata. For more opinionated public docs, pair Ink with the ARK docs hub template.
Familiar UX, your infrastructure, no per-seat pricing, and customizable with AI. The tradeoff: Notion has a bigger feature surface (databases, formulas). Ink focuses on being a great editor + wiki.
Edits queue locally and sync when you're back online, but a live connection is still the primary mode. Full offline-first is on the roadmap.
