App Assets Generator

App Assets Generator turns your app into a complete set of store assets in one pass: marketing screenshots (slides), store copy, and ASO keywords. Give it your app, pick a tone and a platform, and it generates everything ready to download.

Every full generation counts against your daily limit. Sign in is required so the AI stays available and fair for everyone.

Screenshots (most reliable)

Switch to the Screenshots tab and upload up to 6 screenshots of your app. Claude analyses the UI and frames your shots in device mockups. This always works and gives the best result, because the screenshots are real and yours.

URL crawler

Paste your app or product URL. The tool reads the page for real title, description, and text, and live-captures the page as phone-sized screenshots. For public landing pages this works out of the box. For a web app behind a login, use the browser extension below (a plain URL capture would only see the logged-out login screen).

The App Assets Capture extension uses your own logged-in browser session, so it can screenshot pages and modals that only exist after you sign in.

Install (once)

1. Open chrome://extensions and turn on Developer mode.
2. Click Load unpacked and select the extension/ folder.
3. Works in Chromium browsers: Chrome, Edge, Brave, Arc, Opera. No token to set up: it reads your App Assets login from the browser.

Per app

Open your web app in a tab and log in, then either:

• Pick exact views (best for modals and single-page apps): open a view or modal, click the extension, then Add this view. Repeat for each screen worth showing, then Generate. Those exact captures become your slides.
• Auto-capture (multi-page apps): just click the extension, then Generate with no views added. It hands over your session and the generator screenshots your app's pages itself.

Either way it opens the generator with your app URL filled in and starts. Your tone and platform stick between apps, so doing many apps is fast.

Anonymise personal details

If your screens show real names, emails, or faces, tick Anonymise personal details and list any names or handles to redact. Before each screenshot it masks emails and your listed terms and blurs avatar photos. Your own browser tab is restored afterward, so nothing on screen is left changed.

For full control, after generating you can open Blur / edit screenshots above the slides and drag a box over anything (a face, a name, an order number). The slides update instantly, with no regenerating.

Tone

Tone sets the whole visual style of the slides, not only the wording. Bold & confident, Calm & minimal, Playful & friendly, and Professional & precise each have their own palette, typography, layout, and device treatment.

Platform

Platform sets the slide shape and the copy rules. App Store (iOS) and Google Play produce portrait phone slides; Product Hunt and Landing page produce landscape slides. The store copy is written to each platform's conventions.

• Slide concepts: 5 marketing screenshots, each with a selling headline, a use-case annotation, and your app framed in a device. Download each as PNG, all of them, or the full pack.
• Store copy: tagline, short and long description, written for your platform.
• Keywords: primary, long-tail, competitor targets, and an avoid list for ASO.

The complete deliverable in one file:

• slides/ the rendered marketing screenshots (PNG, high resolution), named per platform (for example appstore-6.7-1.png) so they map straight to store upload slots.
• screenshots/ the raw source screenshots used in the slides.
• store-copy.md, keywords.md, slides.md, overview.md all the text.
• pack.json everything in one machine-readable file.
• README.txt a short guide to the files.

Generation runs through a server proxy so the AI key stays server-side and never reaches your browser. For behind-login capture, your session and any credentials are used only for that one capture run and are not stored long term. Screenshots you upload or capture are processed only to build your assets.
