Supplemental curator note

We treat it as a programmable design tool rather than merely a Figma-like UI because `.fig` documents are writable from CLI and MCP surfaces. Validate round trips on real files while it remains v0.x.

Try it in 3 steps

  1. 1

    Open the web demo

    Evaluate the editor and document compatibility without installing the desktop app.

    https://app.openpencil.dev/demo
  2. 2

    Open a design document

    Keep the original when testing an existing .fig file and validate round-trip compatibility.

    Open or create a .fig / .pen document
  3. 3

    Try AI or export

    AI uses the selected BYOK provider externally, so review what design context is sent for confidential files.

    ⌘/Ctrl+J → Try AI, or Export → PNG / SVG / JSX
