Lenso.ai
Lenso.ai is a reverse image search engine that lets you upload a photo or paste an image to find matching pages across the web. It supports JPG, PNG, and WEBP files up to 10MB with minimum dimensions of 200x200px, and searches billions of indexed images for places, people, duplicates, related shots, and text-described matches.
Generic reverse search tools treat every upload the same. Lenso.ai routes queries through category-specific models for faces, places, duplicates, related images, and similar results, plus dedicated flows for face search and copyright tracing. Professional plans add Research Mode with up to 10,000 people and duplicate results, advanced filters for language, domain, date, size, and title keywords, and a Developer tier exposes an API with 5,000 requests per month.
Photographers, marketers, journalists, and rights holders use Lenso.ai to track where images appear online, verify faces, and chase duplicate uploads. The interface is available in more than a dozen languages, free face search is advertised on the homepage, and paid Starter, Professional, and Developer plans unlock result links, alerts, watermark-free views, and API access at different unlock limits.
