Small utilities for your next launch
Free tools for makers launching on marketplaces — no account required, no files ever uploaded.
Marketplace image resizer
Bulk-resize screenshots to any marketplace's exact dimensions — contain-fit, no cropping, padded to match. Runs entirely in your browser.
Device mockup generator
Drop a screenshot into a MacBook, iPhone, or iPad frame and download a high-res PNG. Runs entirely in your browser.
AI product description generator
Paste your product URL and get a launch-ready copy kit — short and long descriptions, plus Product Hunt, AppSumo, and Gumroad copy.
Cover image generator
Turn a few screenshots into a real cover image — pick a background, a layout, and a headline written from your product URL.
No account required
Use either tool right away — nothing to sign up for.
No files uploaded
Nothing you drop in ever leaves your device — the description generator only sends a URL to our AI, never a file.
Free, no catch
No watermark, no trial limit, no upgrade prompt hiding behind the download.
Need more than a resize or a frame?
List Pro turns a screenshot and a feature description into a fully annotated, AI-composed marketing card — sized for the exact marketplace you're launching on.
