This is not a well-shaped retention curve IMO. The others flatten. Muse tilts down extrapolating to zero.
This is one of the best ways to measure product-market fit.
My guess is that many people get fatigued with the proactive notifications and switch them off around week 3/4.
Meta Muse's retention is out, and it's almost as good as ChatGPT!
It's higher than ChatGPT at D7 (>30%) and just lower at D14 (22%). Not quite in the elite D14 tier of WA (67%) YT (59%) Insta (54%) or TikTok/Snap (37%), though.
Muse is one of the highest retaining AI products!
