What is Lenso.ai?

Lenso.ai is an AI-powered reverse image search tool. You upload an image, and it finds matching photos across the web. It specializes in searching by face, place, duplicate, related, and similar images. Each category uses a dedicated AI model to deliver relevant results.

To use it, you drop, paste, or upload an image. The tool then scans billions of images from websites. You can refine results with filters like language, domain, date, size, or keywords. For deeper searches, Research Mode gives you up to 10,000 results for people and duplicates, which is 10 times more than standard searches.

It suits photographers, content creators, and anyone protecting copyrights. You can trace original sources and find exact duplicates. A Developer subscription offers up to 5,000 API calls per month for image and face search. The site also mentions a free face search trial, but it does not detail all pricing plans or limits.

Lenso.ai features

  • Face Search: Finds where photos of your face appear online with high precision by matching facial details.
  • Duplicate Finder: Locates exact copies of your images and traces their original sources across the web.
  • Research Mode: Accesses up to 10,000 results for people and duplicates, giving you 10 times more pages to explore.
  • Advanced Filters: Refines searches by page language, domain, date range, image size, or keyword in the title.
  • Search Alerts: Sets alerts for categories you care about and notifies you when new matches appear.

What you can do with Lenso.ai

  • Upload a selfie to see where your face appears publicly online.
  • Find all duplicate copies of your copyrighted photos across websites.
  • Trace the original source of an image you found on social media.
  • Search for similar images of a product, like a diamond ring, to compare options.

How to get started with Lenso.ai

  1. Go to lenso.ai and drop, paste, or upload an image to start a search.
  2. Choose a search category like face, place, duplicate, or similar to see results.
  3. Use filters or Research Mode to refine results, then save or share your search.

Tips for better results with Lenso.ai

  • Upload the clearest, highest-resolution image you have, since Lenso.ai matches based on visual details and a blurry photo will return fewer relevant results.
  • Use Lenso.ai's Research Mode when you need exhaustive results for people or duplicates, because it returns up to 10,000 matches instead of the standard search limit.
  • Apply advanced filters like language, domain, date range, and image size in Lenso.ai to narrow down large result sets and find the exact source or copy you need.
  • Set up search alerts in Lenso.ai for categories you care about, so you get notified when new matches appear without manually re-running the same search.

Lenso.ai pricing

Lenso.ai has a free way to start, with paid plans for heavier use. Check lenso.ai for current limits and prices.

What to check before you rely on Lenso.ai

  • Check the free plan limits before relying on Lenso.ai for regular work, since the site mentions a free face search trial but does not list all plan details or search quotas.
  • Verify whether your intended use case, like tracing copyrighted images, is covered by the free tier or requires the Professional plan, as Research Mode and advanced filters are not free.
  • Confirm the export options and data handling policies for your uploaded images, because the website does not state how long images are stored or whether they are used for training.
