 ## Features
 
 - **Figma .fig file import and export** — read and write native Figma files
-- **Copy & paste with Figma** — select nodes in Figma, paste into OpenPencil (and vice versa). Uses Figma's own fig-kiwi clipboard format
+- **Copy & paste with Figma** — select nodes in Figma, paste into OpenPencil (and vice versa). Uses the same Kiwi binary format as .fig files
 - **Real-time collaboration** — P2P via WebRTC, no server required. Cursors, presence, follow mode
 - **Drawing tools** — shapes, pen tool with vector networks, rich text with system fonts, auto-layout, components with live sync, variables with modes and collections
 - **AI chat** — describe what you want, the AI builds it. 29 tools wired to chat, CLI, and MCP

 Select nodes in Figma, <kbd>⌘</kbd><kbd>C</kbd>, switch to OpenPencil, <kbd>⌘</kbd><kbd>V</kbd> — they appear with fills, strokes, auto-layout, text, corner radii, effects, and vector networks preserved. Works the other way too: copy from OpenPencil, paste into Figma.
 
-Under the hood, both directions use Figma's own fig-kiwi clipboard format — the same base64-encoded Kiwi binary that Figma puts on the clipboard. OpenPencil decodes the full schema on paste (194 definitions, ~390 fields per NodeChange) and encodes it on copy. Vector data round-trips through the `vectorNetworkBlob` binary format. Also works between OpenPencil instances via a separate native clipboard format.
