What Whos offers
Its defining tool is reverse-image search: upload a screenshot from a scene, and the engine attempts to match it to a title, returning the alphanumeric ID code — sone-131, ipx-504 — that JAV fans use as shorthand for specific films. Matches come back with related scenes and counts of similar titles. Beneath the matcher sits a structured encyclopedia. Film pages collect HD highlight screenshots and online streaming options, while an actress database the site counts at more than 23,000 performers links individuals to their work histories. Frame exploration surfaces timestamped stills from across the catalog, and separate leaderboards track videos, actresses, and members, the last ranked by points across weekly and all-time boards.
Accounts carry real weight here: favorites, ratings, and search functions require a Whos.tv login, and a points system rewards sharing material and completing tasks, with boards recognizing the most helpful answers. The interface is Chinese-first, with a full English version, and the scope is deliberately narrow — a retrieval and reference engine for Japanese AV instead of a general tube site. For someone holding a mystery screenshot, or tracing one performer's catalog scene by scene, that focus is the point.
