Sensor Tower: Muse retention beats ChatGPT/Claude/Grok — but Meta is buying it
Sensor Tower data via TechCrunch shows Muse retained 30% of US users after 7 days and 23% after 14 days, beating the ChatGPT/Claude/Grok average of 19% and 16%, with 10.2M US downloads in 40 days and ~2.5M daily actives. The asterisk: Meta devoted 39% of its total October advertising spend to Muse, up from 23% in September, pushing it to the 21st-largest US brand by ad impressions. Growth is real; whether it's organic is an open question.
