Vibe Coding the LoopedIn Crochet App with Kimberly Erni & Pei Pei Wang

Today, co-founders Kimberly Erni and Pei Pei Wang join the Elixir Wizards to discuss their crochet app, LoopedIn. Recognizing a gap in the market for a more user-friendly and interactive crochet pattern experience, they're building an app that makes following patterns easier and more enjoyable for crocheters of all skill levels. They're building features such as step-by-step guidance, video tutorials, and the ability to upload and convert PDF patterns into an interactive format. Kimberly explains how she's leveraging AI tools to vibe code in Elixir and LiveView. They highlight the challenges and successes they encountered while creating a Progressive Web App (PWA) that integrates AI-powered features. They also discuss their user research and testing process, which involved gathering feedback from the crochet community to prioritize features and improve the app's UX. Kimberly and Pei Pei share their thoughts on the potential of AI in the tech industry and how it has assisted them in the development and iteration process. They emphasize the importance of understanding the code generated by AI and the need for proper testing and verification. They offer advice to others looking to create passion projects, stressing the value of finding a partner with complementary skills and shared enthusiasm for the project.
