Shotluma

An AI-first, local-first canvas editor for creating complete iOS App Store screenshot sets in the browser. The AI agent builds real, editable designs instead of flattening your ideas into generated images. Describe your app, upload raw screenshots, and an AI agent designs the full set — not as opaque bitmaps, but by driving the same editor operations you'd use by hand. Every text layer, gradient, shape, and device mockup it places stays a real canvas element: select it, restyle it, move it, or redo it manually. Then export every artboard at exact store resolutions. Projects live entirely in your browser — no Shotluma account or project backend. The editor itself works without AI credentials. For AI generation, connect a local Codex app/CLI signed in with your ChatGPT plan, or bring your own provider key. Shotluma is the open-source project realZachi/shotluma (https://github.com/realZachi/shotluma) by realZachi, released under MIT. Ion packages it unmodified from commit fd92c2ac889e, adding only a manifest, an icon and a storage compatibility script.
