GPT means Get-Paid-To, not AI. A GPT or rewards site lets users complete offers, surveys and games from offerwall partners, earn points, and cash those points out. The site earns a share of what advertisers pay for each completed offer. ### Can you add offerwalls to my existing site or app? Yes. I integrate offerwall partners into an existing site, including the postback endpoint, signature checks and a ledger that credits users only after the network confirms a conversion. For apps, I build native iOS and Android offerwall SDKs. ### Do you only design, or do you build too? Both, on my own: product design, frontend, backend, admin panels, deployment, and mobile apps. Every project on this site was built that way. ### Which stack do you use? Laravel with Filament and Livewire, or Inertia with React and TypeScript, and Tailwind on the web. Flutter for cross-platform apps, Swift and UIKit for iOS SDKs, Kotlin for Android SDKs, with MySQL and Redis behind them. ### Who owns the code? You do. You get the repository, the deployment and a walkthrough of the admin and the code. ### How do we start? Send a short brief through the form, or message me on Telegram or WhatsApp. I reply within one business day with questions, a rough scope and the closest project to look at. ## Optional - [Full case studies](https://gpt.ziadt.dev/llms-full.txt) - [Privacy](https://gpt.ziadt.dev/privacy/)
