Steve Moraco leveraged Replit to build an AI service called DATA that replaces Siri with ChatGPT, and it has scaled rapidly to $18k MRR, 800 paid subscribers, and 100k+ impressions. DATA is a digital assistant built for iPhones using Apple Shortcuts, which can solve tasks across various Apple applications and devices. To get started, users create an account on HeyDATA.org, go through the setup process, and install several Shortcuts that have specific functionalities such as creating long-term LLM memory, connecting to Calendar and Weather apps, and transcribing audio files into text. Replit has been pivotal for DATA's rapid development and scalability, enabling Steve Moraco to spin up an entire business and AI-powered iOS application service with ease. The platform offers a seamless editor, package manager, and generative coding functionality through Ghostwriter, which enabled Steve to quickly prototype and deploy applications. DATA promises a user-focused approach that emphasizes efficiency, integration, and adaptability, and its success can serve as a case study for developers looking to build on Replit.
