Pencil – Design on canvas. Land in code.

Overview

Pencil – Design on canvas. Land in code – is an AI-powered design canvas built directly into your IDE, so your UI and your code always stay perfectly in sync. Instead of jumping between design tools and engineering workflows, product teams can sketch, iterate, and ship from a single, developer-first environment. Pencil uses agent-driven intelligence to translate visual layouts into production-ready code with pixel-perfect alignment. Designers can explore ideas on an infinite canvas, while engineers see instantly how those decisions map to components, tokens, and real project structure. Every change stays grounded in your existing codebase and tech stack, helping teams move faster without losing control over implementation details. With live previews, layout suggestions, and smart refactors, Pencil eliminates the friction between design specs and actual UI code. It’s built for modern front-end workflows, supporting rapid prototyping, tight design–dev collaboration, and continuous iteration. Whether you’re refining a design system, implementing new product surfaces, or cleaning up legacy interfaces, Pencil keeps your canvas and your codebase aligned at every step. For teams tired of static mockups and handoff docs, Pencil turns your IDE into a shared visual workspace where designs are always executable and code is always design-aware.
