When I run, I collect all my training data in Strava. When I actually want to understand that data, or get some coaching out of it, I don't open Strava. I bring the data to Claude instead.
That's a small, personal habit, but it points to a bigger question every product team is now facing. Where should intelligence live? Inside your product, where you build and control the whole experience? Or outside it, in the assistant your customer already has open, Gemini, Siri, Claude?
That's not just a fitness question. Products used to compete only with others in their category. Now they compete with whatever AI system a user turns to for the same task.
