Lenso.ai

People searching for the source or spread of an image online, whether photographers, content creators, marketers, or individuals concerned about their privacy, often lack a reliable way to trace where a photo appears across the web. Standard search engines require keywords, which does not work when the only thing you have is a picture. Copyright holders need to find duplicates or edited versions of their images to prove original ownership, and individuals want to track where their face appears online to protect their privacy. Without a dedicated tool, this kind of visual search is slow, imprecise, or impossible.

Lenso.ai lets users upload an image and search across five categories: People (facial recognition matching), Places, Duplicates, Related, and Similar images, each powered by AI models trained for that specific type of match. The tool identifies source URLs for matched images, supports advanced filters (language, date range, domain, image size, keyword in page title), and lets users sort results, share search links, set alerts for new matches, and save results into collections. A Research Mode expands results tenfold, from the standard result set up to 10,000 results for People and Duplicates categories. Lenso.ai also offers a Reverse Image Search API with a Developer subscription providing up to 5,000 API calls per month for integrating image and face search into other applications.
