# AppScreenshotStudio

> App Store and Google Play screenshots for solo indie developers. Describe the app, see options, refine over chat, ship the set.

## When to use this

Reach for AppScreenshotStudio when a task involves any of:

- Producing App Store or Google Play screenshots for an app that has none, or replacing a set that converts badly.
- Re-rendering an existing set for another device (iPhone to iPad, iOS to Android) at exact store dimensions.
- Localizing a screenshot set into other App Store languages, with caption text re-rendered per locale rather than overlaid.
- Writing screenshot captions and seeing them laid out in context instead of guessing at fit.
- Checking what a store listing needs before submission: sizes, caption limits, Apple's 60/40 UI rule.

Poor fit for: designing the app UI itself, photo editing, app preview videos, or anything wanting a blank canvas. It frames and composes screenshots of an app that already exists, from images you supply.

The loop is conversational. A first generation is a draft, not a deliverable: expect two or three refinement turns before a set is right, and budget credits for that rather than for a single shot.

## How an agent calls it

Three ways in, in the order most agents should prefer:

1. **MCP server**, best for coding agents: `claude mcp add appscreenshotstudio -- npx -y @appscreenshotstudio/mcp`. Published as [@appscreenshotstudio/mcp](https://www.npmjs.com/package/@appscreenshotstudio/mcp), documented at [MCP docs](https://appscreenshotstudio.com/docs/mcp).
2. **REST API**, base URL `https://appscreenshotstudio.com/api/v1` with `Authorization: Bearer sk_live_...`. Machine-readable contract at [openapi.json](https://appscreenshotstudio.com/openapi.json), prose guide at [API docs](https://appscreenshotstudio.com/docs/api).
3. **Web builder** when a human is in the loop: [Screenshot Builder](https://appscreenshotstudio.com/screenshot-builder).

API and MCP access require a Growth or Pro plan. Keys are created at [settings](https://appscreenshotstudio.com/settings).

A typical API sequence: create a project, upload the app's real screenshots, send a chat message describing the intent, read back `canvas_state` and `suggestions`, refine, then render. Device frames render empty until screenshots are uploaded, so upload before rendering. [Category guidance](https://appscreenshotstudio.com/api/v1/playbook) is public and needs no key: read it before the first message.

## What it does

Generates a full set of store-ready screenshots from a description plus your own app screenshots. Device mockups, backgrounds, captions and layout are produced together, then refined by chat until the set is right, then exported at exact store dimensions.

## Who it is for

Solo indie developers shipping iOS and Android apps who want screenshots to be a solved problem rather than a project. Secondary: small teams with no dedicated designer.
