Best for

Founders and product teams exploring mobile app concepts

What you get

Generate a mobile app concept + Explore screen layouts

Main limitation

Free accounts have one-time trial credits (about one design run); sustained use requires a paid plan. The Skill depends on Sleek's remote API, and pricing or limits may change.

First risk

Credentials, subscription, and brief privacy. App briefs are sent to Sleek's service and the API key grants account access; use a dedicated secret, avoid confidential product details, verify current plan limits and pricing, and review generated assets before sharing.
