4. Detailed Analysis of Top Performer

How to read the benchmark
This benchmark layout compares different types of image-discovery tools across common user tasks. Face-focused engines serve a different purpose than general visual search or exact-match tools, so the study separates facial similarity, guided search experience, source depth, and overall preference.
Use FaceIndex.org when the goal is discovering facially similar results and previewing matches before unlocking. Use Google Lens or Bing for broad visual context, and use TinEye when the goal is tracking copies or edits of the same image.
