Shotluma

Shotluma is an AI-powered App Store screenshot generator that works like a design tool. Describe your app, drop raw captures, and the AI lays out a consistent multi-screen story. The key difference: everything the AI produces lands on the canvas as real, selectable layers (text, shapes, gradients, device frames). You can restyle, move, or replace any layer after generation.

The editor runs entirely in the browser; projects live in IndexedDB, nothing is uploaded. AI generation is bring-your-own-key (Google, Qwen, OpenAI, Anthropic, xAI). Exports are 1290×2796 or 1242×2688 PNGs packaged in a ZIP, ready for App Store Connect.

The source is MIT licensed, with no paid tier, no seat count, no usage cap. It's a finished, remixable tool for indie developers who need store-ready screenshots without a design tool.
