AI Mobile App Design Chat SaaS

Chat with AI to produce polished mobile app screens for founders who cannot hire a designer.

In plain English

Founders who cannot hire a designer chat with Sleek and get polished screens for a mobile app. A free try covers a small project, paying opens more projects plus extra design credits, and the finished screens can be passed on so someone else can build the app. Founders pay because a clean set of screens usually needs a designer they do not have. The AI makes most of the screens, handles billing, and stores the projects. The person running Sleek still watches design quality, talks with builder communities, and answers support questions.
