Lenso.ai

Lenso.ai is an AI-powered reverse image search engine that finds where a photo appears online across billions of web images, with dedicated models for faces, places, duplicates, related, and similar images. It's aimed at photographers, artists, marketers, and privacy-conscious individuals who want to trace original sources, protect copyrights, or find pictures of a person or place — no keywords needed, just an uploaded image. What sets it apart is its category-specific facial recognition search plus a Research Mode that surfaces up to 10,000 results (10x normal), and a developer API for building the search into other apps.
