The missing
design mode
for Codex

Mowgli is a perfect tool for visual, AI-assisted development.

It strikes a nice balance between teasing out the details that make your project special, building out a comprehensive design, and allowing edits based on broad strokes or nitty-gritty details. From there, you can easily transport your work to a development environment, making the interoperability and time savings immeasurable.

Mowgli lets us ship features and test ideas with our market way faster at Hey Lilie.

Unlike other vibe design or vibe coding tools, the product scoping layer means you actually think through the problem before jumping into screens. The output respects our brand and design system out of the box, which is something I haven't seen anywhere else. It's the missing step between having an idea and building something that makes sense.

I discovered Mowgli by chance through a friend's recommendation, and it has become an essential tool for our development process.

Mowgli allows us to quickly model different UX approaches and leverage its suggestion engine. The resulting mockups streamline the design process for both client projects and internal products. The AI responds effectively to revision requests, enabling detailed work on every screen. We have seen significant improvements in production quality, workload management, and delivery timelines. Our application projects are now much better organized. Package exports for coding AIs allow for rapid implementation. We now consider Mowgli a full-fledged interface designer on our team.

Mowgli is one of those rare tools that actually makes you a better founder.

The onboarding brainstorming alone gave me angles on my business I hadn't considered, helping me build a much more complete product from day one. From PRD to design, everything is incredibly intuitive. What blew me away most is the design quality: Mowgli turns your ideas into mockups and prototypes with a UI/UX polish that's better than what you had in your head. No need to hire a designer or pay a fortune. And the best part is it evolves with you as your product grows. The variety of export options meant I could go straight from Mowgli into building my app. Whether you're a solo founder or an established business looking to move fast, reduce costs, and still ship professional quality work, I can't recommend it enough.
