A design screen for your agent.

Screenie gives your agent a canvas to render and iterate designs on — then export them as high-res PNGs, or hand off straight to your coding agent to ship to production.

Proof of work

Screenie was designed in Screenie.

Every panel of the app — and the page you're reading right now — came off Screenie's own frames. The agent designed, we approved, Copy prompt built it. No Figma file exists.

should we make it export pngs/pdfs? or ship to prod? should we state what file they're exporting?
Yes — name it. Concrete beats vague on a landing hero. Rec: "export high-res PNGs, or hand off to your coding agent to ship to prod."
Done. Subhead now reads: "…then export high-res PNGs, or hand off straight to your coding agent to ship to production."

What can you do in Screenie?

One screen for everything you ship.

Point Screenie at your codebase, your brand, or a blank prompt. It renders on the right frame and hands off ready to ship — five things teams do every week.

01 Ship your mobile app

Design your app on its own components — then ship it.

Attach your mobile codebase, describe a screen, and iterate against your real components and tokens. Approve it, hit Copy prompt, and hand it straight to your coding agent.

Production-ready code in your own design system — not a redraw.

02 On-brand content

Turn your brand guidelines into content that ships.

Reference your design system and brand assets, then generate posts, stories, and carousels for every platform — the agent holds your palette, type, and voice on every slide.

On brand, exported pixel-perfect at each platform's exact aspect ratio.

04 Web · Full page

Design full landing pages, hero to footer.

Describe the page and Screenie lays it out as live HTML — real sections, real hierarchy, reflowing like the shipped site. Export a PNG or hand the spec to your coding agent.

A working spec you can ship — not a flat picture of a page.

05 Desktop app

Design a desktop app — the way we designed Screenie.

Native window chrome, sidebars, dense dashboards, dark panels. Describe the flow and iterate on real screens. The app you're reading this in was designed exactly like this.

Every panel of Screenie came off these frames — yours can too.
