StoreScribe: An Open Model Tool for Automated App Store Listings

StoreScribe is a new open-source tool designed to help indie developers automate the creation of App Store and Google Play listings. Built for the Hacktoberfest AI Challenge, the tool utilizes Google's Gemma 4 model to generate optimized app descriptions, titles, and keywords in up to six languages. By leveraging vision capabilities to analyze screenshots and integrating with SerpApi for competitor research, StoreScribe ensures listings adhere to strict platform character and byte limits. The project includes both a web interface and a CLI that scans project repositories—supporting Flutter, React Native, and native mobile stacks—to generate metadata files automatically. By running locally via Ollama or on DigitalOcean serverless infrastructure, StoreScribe offers a cost-effective, privacy-focused alternative to expensive ASO agencies. The project is open-source, MIT-licensed, and demonstrates how combining LLMs with rigorous programmatic rule-checking can solve complex content generation tasks for mobile developers.
