Built for the way your team actually works.
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.
Spaces for every team
Organize docs into spaces — engineering, design, ops, clients. Each space has its own permissions, templates, and index page.
Real-time collaboration
Multiple cursors, inline comments, @-mentions, and presence. Everyone stays on the same page — literally.
Your docs, your database
Every block is stored as structured JSON in your Supabase. Query it, backup it, feed it to your own AI. No vendor export needed — you already have the data.
Markdown in, markdown out
Paste markdown, export markdown. Ink plays well with your existing docs workflow, static-site generators, and README files.
A complete feature set, grouped by what you're trying to do.

Can we use it like a wiki?
Yes. Spaces + nested pages + search + templates give you a proper internal wiki out of the box.
Does it handle big documents?
Ink loads pages incrementally by block, so long docs stay smooth. Backends are just Postgres rows — there's no artificial size limit.
Can I use it as a public docs site?
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.
How does it compare to Notion?
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.
Is there offline support?
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.
