Lenso
Lenso.ai is a reverse image search platform that uses AI and CBIR (Content-Based Image Retrieval) to locate images across the web. It supports multiple search categories—People (face search), Places, Duplicates, Similar and Related—which produce category-specific results. The service targets content creators, photographers, artists, marketing professionals, researchers and developers who need to locate images, trace original sources, detect duplicates, or find where photos (including faces) appear online.
Beyond web searches, Lenso.ai provides features for deeper research and developer integration: a Developer subscription offering API access (including Image Search and Face Search API), a Professional Research Mode that returns up to 10x more results, and advanced filters to refine searches.
