Americans who have joined RedNote in protest of the U.S. government’s looming ban on TikTok have found new connections across international borders.

With TikTok's days in the U.S. potentially numbered, many American users are moving to another Chinese social media app: RedNote, a heavily censored platform similar to Instagram. Here's what to know.

RedNote has 300 million users, the bulk of those being young women, according to TechCrunch. TikTok, for its part, has 170 million American users. That’s attracted loads of investor attention, with backers including Tencent, Alibaba, and GGV Capital. It’s widely seen to be considered an IPO candidate.
