Magic Patterns Presentations vs pen.dev

Magic Patterns Presentations is a web tool that turns product designs, prompts, or slide outlines into editable presentation decks. It generates copy, layouts, and visuals, and can convert screens from an existing Magic Patterns design into slides. Generated slides may be refined with the AI assistant or edited manually. A connected design system supplies typography, colors, and visual language for branded presentations. Decks can be presented with presenter view, shared by live link, exported as PDF, or linked to an interactive product design. The service targets product managers, designers, engineers, marketing, and sales teams. It offers a free plan with monthly credits; only direct AI generations consume credits, while editing, exports, and sharing do not. Starter costs $20 a month, Business $100 a month, and Enterprise pricing is custom. Paid plans can add on-demand credits at $0.02 each.
