Shotluma is a free, open-source AI-powered App Store screenshot generator that runs entirely in the browser without requiring an account. It allows users to describe their app, add raw screenshots, and generate editable, store-ready screenshot sets with every text layer, gradient, and device frame remaining adjustable.
THE PRODUCT, BEYOND THE PITCH
Editorially reviewed · Sources checked Sep 12, 2026
A good fit for
- Users who prefer local-first tools that keep projects and API keys stored only in their browser without uploading data to external servers.
Know the limitations
- AI generation requires users to provide their own API keys from supported providers and pay those providers directly at their rates.
- The software runs entirely in the browser and stores data locally, so it depends on browser storage limits and does not upload projects to any server.
What you can do
- Generating store-ready App Store screenshot sets from raw app captures with editable layers for marketing and app presentation.
- Editing and refining AI-generated screenshot sets directly on the canvas to customize typography, colors, spacing, backgrounds, and imagery.
Features
- Every text, gradient, shape, and device frame remains a live, editable layer after AI generation.
- Supports real device mockups with flat or perspective device frames and correct screen geometry and corner masking.
- Exports complete screenshot sets as 1290 × 2796 or 1242 × 2688 PNGs packaged in a single ZIP ready for App Store Connect.
Integrations
- Supports AI generation using API keys from Google, Qwen, OpenAI, Anthropic, and xAI providers directly from the browser.
Platforms & data export
- Runs entirely in the web browser with no account or server upload required.

A practical workflow
- Describe your app with a few sentences to provide context for copy, hierarchy, and visual direction.
- Add raw screenshots by dragging them in; Shotluma places them inside device frames with correct perspective and masking.
- Generate and refine the screenshot set; the AI lays out a consistent multi-screen story and users can adjust any element on the canvas.
- Export the entire set as a ZIP archive of App Store resolution PNGs ready for upload to App Store Connect.
