# Shotluma

> Shotluma is a free, open-source, AI-powered App Store screenshot generator. Describe your app, drop in raw screenshots, and get store-ready screenshot sets where every text layer, gradient, shape, and device frame stays editable. €0 forever. MIT licensed. No account required.

Shotluma is a local-first browser editor for Apple App Store screenshot marketing. An AI agent drives the real editor (not a flattened image renderer), so every generated element remains selectable and editable. Projects and API keys stay in the browser; the marketing site at shotluma.com does not receive editor project data.

- Export sizes: 1290 × 2796 and 1242 × 2688 PNG, packaged as ZIP. Both are App Store sizes; neither meets Google Play's rule that a screenshot's long side may be at most twice its short side, so Play uploads are not supported today

- Privacy: projects, screenshots, prompts, and API keys stay in the browser IndexedDB / localStorage; they are not sent to marketing-site analytics
