# Overlay Designer > AI generator for photo-booth overlays — the decorated frames with custom text, logo and > transparent photo windows that sit on top of guest photos. Describe a style, place the photo > windows and text, and the AI produces a polished, print-ready overlay (transparent PNG + 300 DPI > PDF). Works with any photo-booth app, and offers a public REST API + an embeddable website widget. ## Key pages - [Home](https://overlaydesigner.com/): what Overlay Designer is and how it works - [Design app](https://overlaydesigner.com/app): the web tool to create overlays - [API documentation](https://overlaydesigner.com/api-docs): the public REST API reference - [Terms](https://overlaydesigner.com/terms) · [Privacy](https://overlaydesigner.com/privacy) ## Photo-booth app guides - [Snappic overlays](https://overlaydesigner.com/for/snappic): AI photo-booth overlays for Snappic booths - [Touchpix overlays](https://overlaydesigner.com/for/touchpix): AI photo-booth overlays for Touchpix - [dslrBooth overlays](https://overlaydesigner.com/for/dslrbooth): AI photo-booth overlays & templates for dslrBooth - [Simple Booth overlays](https://overlaydesigner.com/for/simple-booth): AI overlays for Simple Booth HALO - [LumaBooth overlays](https://overlaydesigner.com/for/lumabooth): AI photo-booth overlays for LumaBooth - [Breeze Systems overlays](https://overlaydesigner.com/for/breeze): AI overlays & print templates for Breeze ## For developers (API) - Base URL: https://api.overlaydesigner.com/v1 - Auth: `Authorization: Bearer ` (create keys in the dashboard) - Capabilities: generate an overlay (async job), restyle, reposition windows, apply an overlay onto a guest photo/video, detect/convert a designer layout into a spec.
