yeah, ~1B active users + when non-tech people think of AI, they think of "ChatGPT" not many of the competitors.
Claude has impressive mindshare in many engineering disciplines too, and given how many open source projects are a play on its name I’m not sure I’d argue it isn’t catchy either. Certainly rolls off the tongue easier for me than “chatGPT” does, which even Sam Altman their CEO agrees is an awful product name they are stuck with.
