Inkury

Everything you need to write, together.

Inkury combines local-first reliability, real-time collaboration, and controlled AI assistance in a single editor. Here is what that looks like in practice.

Local-first storage

Every keystroke saves to your device before it touches any server. If your network drops, your browser crashes, or our servers go offline, your document is already safe on your machine. When connectivity returns, changes sync automatically.

  • Offline-capable by default
  • Automatic background sync
  • Works on planes, trains, and bad hotel Wi-Fi
  • No loading spinners -- ever

Deterministic document replay

Every edit creates a precise, ordered record. You can reconstruct any document to any point in time, see who changed what, and revert individual changes without losing everything after them.

  • Full version history
  • Per-change attribution
  • Surgical reverts (undo one change, keep the rest)
  • Audit trail for compliance

Fast at any document size

A 10,000-block document feels as responsive as a 10-block one. We virtualize rendering so only visible content hits the DOM, and we batch writes to avoid layout thrashing.

  • 16ms keystroke-to-paint target
  • Virtualized block rendering
  • Batched DOM updates
  • No jank on large documents

Security built into the editor core

Inkury converts all incoming content into a structured canonical model. Pasted HTML, imported Markdown, and API inputs all pass through the same sanitization pipeline. Unsafe DOM writes are blocked before they execute.

  • XSS-resistant architecture
  • Content Security Policy enforcement
  • Plugin sandboxing
  • End-to-end encryption (Team and Enterprise)

Real-time collaboration with CRDTs

Multiple people can edit the same paragraph at the same time without conflicts. The CRDT engine merges changes deterministically, so everyone converges on the same document state without manual conflict resolution.

  • Conflict-free concurrent editing
  • Suggestion mode with approval workflows
  • Presence indicators and cursors
  • Works across time zones and connectivity gaps

AI that you control

AI proposes changes through the suggestion system, the same system your human collaborators use. Every AI edit is visible, reviewable, and reversible. AI cannot silently rewrite your content.

  • AI suggestions appear as tracked changes
  • Accept, reject, or modify each suggestion
  • Context-aware writing assistance
  • Runs within your security perimeter
