App Store screenshot generator: from URL to export in 10 minutes

App Preview Kit reads your product URL with Jina Reader, extracts your app's key features and value props, writes caption variants specific to your app (not generic templates), maps them onto one of 47 device-specific templates, runs Apple guideline compliance checks, and exports a ZIP with every required device size — all without Figma.

Yes. Every caption is editable in the inline text editor before export. You can also re-run caption generation with a different tone directive — for example, 'write for enterprise IT buyers' versus 'write for indie gamers' — and the AI rewrites all captions in that voice.

The export ZIP contains PNG files at the exact pixel dimensions required by App Store Connect — one file per device size per screenshot. PNGs use sRGB color profile by default; Display P3 output is available on Pro and Team plans. JPEG export is available but not recommended for screenshots containing text.
