Pen-pal studio is the latest development in my quest to get AI agents to produce high-quality, editable, and always-on-brand digital design.
A standalone Mac app
Built in Electron and powered by Claude, it brings a dedicated UX to produce, edit, manage, approve and export digital design assets, created over a purpose-built brand design system.
The path here
I've been pursuing this for a while, and the same core idea has assumed different forms over time.
The difference here is that you don't even have to open a design editor.
It has a headless mode, meaning that you can ask pen-pal to use Pen.dev autonomously to create assets from your design system based on a brief, and bring back the results for you to approve and/or edit.
Submit a job brief and come back to the resultsYou can also use it as a design copilot while you are working on the canvas.
Open the live project and work alongside Claude, or make changes yourself.

Optimized for building, managing and using brand data or a design system.

What's next will be a big deal! (WIP, tho)
Pen-pal is about to get its own internal canvas, with layout, text and vector editing tools, image generation, and design system management.
Next step: a native canvas.
