What is Lenso.ai?
Lenso.ai is a reverse image search engine that takes a picture as the query instead of keywords. It uses separate AI models for different result categories: people, places, duplicates, related images and similar images. The duplicates category is aimed at tracing original sources and spotting copies, including edited versions and other resolutions, which the site presents as useful for copyright protection. Face search matches facial details to find other photos of the same person and is available only in selected regions. Results can be narrowed with a website address or keywords, sorted, shared by link, saved into collections and monitored through email alerts when new matches appear. Paid plans named Starter, Professional and Developer unlock source links; Professional adds a deeper Research Mode and advanced filters, and Developer adds an API.
