Business Model

Mix of one-time, subscriptions & credits.

Target Audience

Asking Price Reasoning

The price reflects its multiplatform availability (iOS, Android, Web), early revenue, 1,000 MAU, zero fixed costs, and strong growth potential with marketing.

Reason for Selling

I built it as a side project to validate structured AI prompt generation. It now has paying users and active traction, but I don’t have the time to continue growing it.

Growth Opportunity

My product is still very early stage — launched only 3 months on Android and 1 month on iOS — yet it already has 1,000 monthly active users, consistent daily activity, and paying subscribers.

30 days free support from seller

Competitors

My platform competes with other AI prompt marketplaces and prompt engineering tools such as: • Promptbase (prompt marketplace) • PromptPerfect (prompt optimizer) • Other smaller AI prompt libraries and template apps on App Store / Play Store.

Tech Stack

Flutter, RevenueCat, ChatGPT, Firebase, Google Firestore, Gemini API.
