What Lenso.ai is
Lenso.ai runs reverse image search. Upload an image and it looks for visually similar material across categories the vendor describes as people, places, duplicates, similar and related, using content-based image retrieval rather than metadata alone.
What you can do with it
- Trace where an image came from
- Check whether your own photos appear elsewhere
- Find duplicate copies of an image
- Verify images before using them
- Monitor a person's or brand's imagery
Who it is for
- Photographers and content platforms
- Brand and copyright teams
- People checking misuse of their images
What to watch out for
- The people category is face search: using it on someone without their knowledge is surveillance and, in several jurisdictions, restricted biometric processing
- Matches are similarity, not proof of identity or ownership
- Do not use it on children or to track partners, employees or strangers
- Verify the context behind any match before acting on it
