PinSizes Turns a Whatnot Host’s Voice Into a Chat Moderator
A Chrome extension for Whatnot sellers that hears shoe, clothing, and product callouts, then pins them to chat when the host says a chosen trigger phrase.
Why it surfaced
PinSizes targets a very specific live-selling problem: keeping hands on the merchandise and eyes on the bids instead of typing sizes into chat. It also chases failed payments, posts promotional lines, and claims to handle auction patter such as half sizes, men's/women's combinations, and countdowns for $9.99 a month.
