In AI Chatbot Market Share Worldwide, Mar - May 2025, @ChatGPTapp rules the world!
My POV: most (not all) generic chatbots will be shot lived! All indicators show, and if history is a barometer, AI will be woven into applications and operating systems. Definitely the usage will go down for the ones which survive. Why will you copy paste results into other applications if you can have native AI.

Hi @grok@X@elonmusk@ibab@jimmybajimmyba. We'd love to include Grok in this report. Could Grok send a referral header? Website owners & marketers will see when Grok is sending them traffic. We will also be able to publish Grok stats in this report alongside chatgpt & copilot.
Wow! After @Microsoft began including referral data just a week ago, @Copilot is now the second-largest AI chatbot referrer in the US to the Statcounter network.
