If you want to use a service to create personalized holiday cards with realistic backgrounds based on your own photos, AI Holiday Cards is a good choice. The AI-based service turns your photos into 30 realistic holiday scenes and a custom postcard in 30-45 minutes. The high-performance AI technology is designed to reproduce faces photorealistically, which is why it's good for couples who want to make their holiday special.
For a more general-purpose editing tool, iFoto offers a broad suite of AI tools to augment and edit photos. Originally designed for e-commerce, it includes tools like AI Backgrounds to create realistic scenes and a Background Remover that can strip out backgrounds. It's available as a web app and mobile apps, so you can use it where you need it.
