Ad Creative Variant Studio

Build an offline product ad editor with this Codex prompt. Upload your image, enter checked product details, and get matching photo colors automatically. Compare Benefit, Feature and Offer layouts, then export PNGs at 1080x1080, 1080x1350 or 1080x1920. Includes local upload, preset palettes, live preview and reset. Product copy is entered by the user; the app does not recognize products or generate images. No API, account or server required to run the finished app.
