Earlier this week Elon Musk rebranded Twitter to X – another step in his plan to emulate Chinese mega app WeChat.
Mr Musk has long said that he wants to transform his social media firm, which he bought last year for $44bn (£34.4bn), into a much larger platform.
He has previously praised WeChat – a so-called “everything app” that combines chat, dating, payments and social media – and has said creating something “even close to that with Twitter… would be an immense success”.
In a post on X this week, Mr Musk said that over the coming months, “we will add comprehensive communications and the ability to conduct your entire financial world”.
He will hope that growing X will lead to a jump in revenue – the company has lost almost half its advertising revenue since Mr Musk bought it, and it is struggling under a heavy debt load.
So what is WeChat - and why does Mr Musk want to emulate it?
Launched by technology giant Tencent in 2011, WeChat is now used by almost all of China’s 1.4bn people.
Calling it a super-app is an understatement.
Its services include messaging, voice and video calling, social media, food delivery, mobile payments, games, news and even dating.
It is like WhatsApp, Facebook, Apple Pay, Uber, Amazon, Tinder and a whole lot more rolled into one.
It is so woven into the fabric of Chinese society that it is almost impossible to live there without it.
