FAQ about Pencil AI

QWhat exactly is Pencil AI?

Pencil AI is an IDE-native AI design tool built on the “design-as-code” principle—design in your editor, export production code instantly.

QWhat can it do?

Visual canvas in VS Code/Cursor, AI UI generation from prompts, Figma-to-code export, real-time design-code sync and component-level editing.

QHow do I install and run it?

Install the extension from the VS Code or Cursor marketplace, open a .pen file and start prompting or import Figma. A standalone desktop build is also available.

QIs it free?

Currently free while in early access; paid tiers may follow—check the official site for updates.

QWhich languages or frameworks does it export?

Generates production-grade front-end: HTML, CSS, React components with Tailwind CSS out of the box; more frameworks on the roadmap.

QHow is it different from Figma?

Figma is a standalone design app; Pencil AI brings the design surface into your IDE so you iterate, commit and ship in one place.

QDo I need design skills to use it?

No. Plain-English prompts create UI automatically, and the familiar canvas lets you refine details if needed.

QHow are design files stored and managed?

Every design is a human-readable .pen JSON file—commit it, diff it, review it like any other source file.

QCan my team collaborate on the same file?

Yes. Because designs live in Git, your normal branching, pull-request and code-review workflow handles collaboration. Join the Discord for extra help.
