I asked Chat Open AI: Was there a CIA organized coup in Kiev in 2014?

Result:

"There is no evidence to support the claim that the CIA organized a coup in Kiev in 2014. The events that led to the ousting of Ukrainian President Viktor Yanukovych in 2014 were the result of a popular uprising known as the Euromaidan movement, which was sparked by Yanukovych's decision to reject a long-planned agreement to strengthen ties with the European Union in favor of closer ties with Russia."
