## What is Shotluma?

Shotluma is a local-first browser editor for App Store screenshot marketing. An AI agent drives the actual editor — real text layers, real shapes, real device frames — so every generated element stays selectable and editable. It is MIT licensed, costs €0 forever, and requires no account.

## How it works

1. **Describe your app** — type a short description; the AI uses it to design the set.
2. **Drop in raw screenshots** — PNG, JPG, or WebP into device frames with correct perspective geometry.
3. **Get the full set** — a multi-screen story on portrait artboards, with every layer editable.
4. **Export and leave** — 1290 × 2796 or 1242 × 2688 PNGs in one ZIP.

## Examples

Four screenshot sets built with Shotluma are shown on the homepage, twenty screens in total:

- **Datafast** — analytics for founders (Growth pulse, Buyer sources, Live visits, Every site, At a glance).
- **PartnerDeck** — Shopify partner earnings (Know your numbers, Live feed, Shops, Alerts, Control room).
- **Noah** — a private parenting journal (Clear picture, Small wins, Voice entry, Ready to share, Private by design).
- **Mononote** — a single-note focus app (One note. Zero noise., Glance, Pinned, Fresh, Everywhere).

Each set uses a different design system and was exported at 1290 × 2796 with every layer still editable.

## Product pillars

| Pillar | Detail |

## FAQ

### What is Shotluma?

Shotluma is a free, open-source, AI-powered App Store screenshot generator. You describe your app, add raw screenshots, and get a store-ready set in which every text, gradient, shape and device frame stays editable — not a flattened image.

### Is Shotluma really free?

Yes. Shotluma is MIT licensed and costs €0 forever. There is no paid tier, no freemium gate and no usage limit. AI generation uses your own provider key, so those runs are billed by your provider at their rates.

### Do I need an account?

No. Open the editor and start working. There is no signup, no email verification and no sales step.

### Where is my data stored?

Projects, screenshots, prompts and API keys stay in your browser — IndexedDB for projects, local storage for keys. They are never sent to a Shotluma server or to this site’s analytics.

### Which AI providers does Shotluma support?

Google, Qwen, OpenAI, Anthropic and xAI work directly in the browser with bring-your-own keys. Moonshot is available in local development through a CORS proxy. Each key is sent only to the provider handling that request.

### Which export sizes does Shotluma produce?

1290 × 2796 and 1242 × 2688 PNG App Store screenshots, downloaded together as a single ZIP archive.

### Can I use Shotluma for commercial work?

Yes. The MIT license permits commercial use, modification and redistribution. Exported screenshots are yours with no attribution requirement.

### Can I self-host or modify Shotluma?

Yes. Clone the repository, run it locally with Bun, and change whatever you need. Pull requests are welcome and there is no contributor licence agreement to sign.
