Storyboard

Crank Storyboard is GUI Design and Development software that enables engineers and designers to create optimized GUIs for embedded devices rapidly and with ease. So much so that device manufacturers at Fortune 500 companies rely on Storyboard to help them create their award-winning, innovative touch screens for their smart kitchens, white goods, cars, and industrial devices. We're their secret sauce. Our proprietary design and development platform encourages GUI designers and software engineers to work side-by-side for maximum efficiency, yet independently so they can validate designs and performance much earlier, handle iterations in design with ease, and get their products to market faster. All applications created in Storyboard are automatically optimized for maximum performance on a range of platforms from resource-constrained microcontrollers to high-powered microprocessors, meaning a broader spectrum of devices can now have brilliantly-designed GUIs, without draining resources to run them. How does it work? Storyboard does not generate source code to be compiled but instead generates a data model that is in turn executed by an engine that is specifically targeted for resource-constrained embedded systems. Storyboard is specifically designed to be extensible and timeless. By not relying on a specific set of GUI widgets but instead leveraging standard file formats for graphics and fonts, Storyboard allows designers to craft GUIs using tools that they are most familiar with such as Figma, Photoshop, Sketch, and 3D modeling software. Later on, when the GUI needs a design update, the interface can be quickly re-skinned with a new look without affecting the underlying logic of the system.

Moonchild AI

Moonchild AI is an AI design platform built for product teams to design UI screens, user flows, and interactive prototypes that match their brand and design system. The platform helps teams move from product requirements and ideas to production-ready design directions in minutes. Moonchild allows users to generate interfaces from prompts, PRDs, screenshots, PDFs, references, and existing product experiences. Every generated screen remains editable, interactive, and connected inside a shared workspace designed for iteration and collaboration. A core part of the platform is its design system workflow. Teams can import or recreate their design systems directly from Figma links, live product URLs, or GitHub repositories. Once connected, Moonchild generates outputs that follow the team’s actual components, styles, spacing, typography, and visual language. This allows product teams to create AI-generated designs that stay consistent with their brand instead of producing generic outputs. The platform is designed for designers, product managers, and engineers working together across the product development process. Designers can explore and refine UI directions on a visual canvas. Product managers can turn requirements into flows and prototypes without manually designing every screen. Engineers can use Moonchild outputs as part of their development workflow through exports and integrations with modern AI coding environments like Cursor and Claude. Moonchild also supports live interactive prototypes, allowing teams to quickly visualize and communicate product ideas before development begins. Users can combine multiple screens into flows, preview interactions instantly, and share prototypes with stakeholders. Moonchild is a bridge between requirements, design systems, and code, helping product teams reduce friction between ideation, design exploration, prototyping, and implementation while maintaining consistency across the entire product experience.
