Pencil

pencil.dev/

The pencil.dev URL now redirects to pen.dev, an agentic design canvas built for handling large volumes of visual content — it specifically claims to handle "10000 photos, 10GB of content, 60fps, no problem" via a custom WebGL rendering pipeline, a performance figure that's unusually concrete for a design tool's marketing page. Its hero states it's "an agentic canvas for building bold ideas," and it supports importing existing Figma files or live webpages (via a Chrome extension or built-in browser) and exporting straight to HTML/CSS/Tailwind. It supports multiple AI models by name — Claude, OpenAI, Grok, Qwen, Gemini, Kimi, Deepseek, Minimax — rather than committing to a single provider, and states it's backed by a16z's Speedrun program.
