App Store Screenshot Generator: AI Copy That Matches Your Keywords
Generate App Store and Google Play screenshot copy from your keyword pool. Headlines and bodies that sell the search intent, not just the feature list.
An **app store screenshot generator** that only resizes images is half a tool. The harder part of a screenshot set is the copy: the headline and the supporting line that tell a searcher why to install in the two seconds they spend on your page. NewASO's Screenshot Studio generates those lines from the keyword pool you already researched, exports them at the exact device dimensions each store requires, and keeps everything local.
Key takeaways
- Screenshot copy should sell the search intent, not just describe the feature.
- Generating copy from your keyword pool keeps screenshots consistent with your listing and ads.
- Each store has different required dimensions; auto-fit by aspect ratio avoids manual resizing.
- Export PNG or JPG at the exact device size — no watermark on Pro.
- The copy is a starting point; always review for tone and accuracy.
Why screenshot copy matters more than screenshot design
Most teams spend hours on screenshot frames and backgrounds, then write the headline in five minutes. That is backwards. A searcher skims the first two screenshots before reading a single word of your description. The headline on screenshot one is your second most important piece of store copy after the title.
Good screenshot copy does three things: names the outcome the user wants, ties it to a keyword they actually searched, and stays short enough to read at thumbnail size. Bad screenshot copy lists features ('Sync across devices', 'Dark mode', 'Offline support') that describe the app but do not answer the question the searcher brought to the store.
How Screenshot Studio generates copy
Screenshot Studio takes your app name, category, and the keyword pool from your research run. It sends those to your configured AI provider (Groq, Claude, GPT, Gemini, or any OpenAI-compatible endpoint) with a prompt tuned for store screenshots: punchy headlines (6-12 words), supportive body lines (8-14 words), benefit-led, no invented features.
The result is a set of headline/body pairs you assign to screenshot slots. Each pair is editable. The tool does not generate images — it generates the copy and the device frame. You bring your own screenshots.
Device dimensions and auto-fit
Screenshot Studio ships with a device catalog covering every store-required size: Play phone (1080x1920, 9:16), landscape (1920x1080), tablets, wearables, TV, automotive, XR, and the full Apple range (iPhone 6.9, 6.5, iPad 13, iPad 11, Watch, TV, Vision Pro). When you upload a screenshot, the tool auto-fits it to the selected device by aspect ratio.
| Device | Dimensions | Aspect ratio |
|---|---|---|
| Play phone | 1080 x 1920 | 9:16 |
| Play landscape | 1920 x 1080 | 16:9 |
| iPhone 6.9 | 1320 x 2868 | 9:19.5 |
| iPhone 6.5 | 1284 x 2778 | 9:19.5 |
| iPad 13 | 2064 x 2752 | 3:4 |
| iPad 11 | 1488 x 2266 | 3:4.5 |
Export and watermark
Export as PNG or JPG at the exact device dimensions. Free users get a watermark on exports. Pro users export clean. The watermark is the only visual difference between free and paid screenshot export — the copy, dimensions, and device frames are identical.
Frequently asked questions
Does Screenshot Studio generate images?
No. It generates the copy (headlines and body lines) and the device frame. You bring your own screenshots. The tool composes them into store-ready images.
Which AI providers work?
Any provider you configure in Settings: Groq, Claude, GPT, Gemini, DeepSeek, Mistral, Grok, OpenRouter, or a custom OpenAI-compatible endpoint. Groq and Gemini have free tiers.
Can I edit the generated copy?
Yes. Every headline and body line is editable. The AI output is a starting point, not a final draft.
What image formats are supported?
PNG and JPG for both upload and export. The tool auto-fits uploaded images to the selected device by aspect ratio.
