"Going to create a site where the public can rate the core truth of any article & track the credibility score over time of each journalist, editor & publication," Musk tweeted.
He said the service could be called Pravda, which is Russian for "truth" and also happens to be the name of the newspaper central to the Soviet Union's Communist Party.
A California business called Pravda Corp was incorporated late last year, with Jared Birchall listed in a filing as its president.
Birchall's name has also been listed in filings for other Musk projects, including The Boring Company.
In response to a tweet noting the Pravda Corp filing, Musk simply offered a hugging face emoji.
"The question is why should Elon Musk be the one running it and how trustworthy would it be if he ran it.".
After one Twitter user raised concerns about Musk fanning distrust of the media, the CEO replied: "The media has earned this mistrust.". »
