1. tipping feature; donation function (on a live-streaming platform)
An online feature that allows viewers to send money to a streamer, creator, or performer in real time while watching or reading their content. Common on live-streaming sites, video platforms, and social media, where it serves as direct viewer-to-creator financial support.

Composed of ()(せん) (tossing a coin; tip, historically a coin tossed to street performers) and 機能(きのう) (function; feature). The original ()(せん) referred to coins thrown to traveling musicians and street performers; the modern digital usage extends this image to online platforms.

USAGE:
A 21st-century tech term. You will see it on service-description pages, news articles about streamers, and in conversations about YouTube, Twitch, niconico, and similar platforms. The 機能(きのう) part can be dropped when context is clear — people often just say ()(せん)をもらう (to receive a tip). On English-language platforms, the feature often has brand names like "Super Chat," "Bits," or "Tips," which in Japanese are grouped under ()(せん)機能(きのう).
