Lensa

Lensa is Prisma Labs' consumer photo-editing app for iOS and Android, best known for its one-tap face retouching, background blur/replace, and the 'Magic Avatars' feature that fine-tunes a Stable Diffusion model on a handful of selfies to produce stylized AI portraits. The core editor leans on neural segmentation to split foreground from background so you can recolor, blur, or swap each independently, plus skin smoothing, eye brightening, and blemish removal that run on-device.

The target user is a phone-first creator who wants Instagram-ready selfies without learning Lightroom. Pricing is freemium: the app is a free download, but the useful retouching tools and Magic Avatars sit behind a Lensa Pro subscription (roughly $35.99/year, with Magic Avatar packs sold as one-off in-app purchases). It's a closed mobile product with no public API and no desktop version.

Lensa drew real controversy around the Magic Avatars launch over training-data sourcing and the way it handled NSFW outputs, so editorial buyers should weigh that alongside its slick UX. For pure casual portrait editing it's one of the better-polished mobile AI apps; for professional retouching or any kind of programmatic use, it's the wrong tool.
