Cosma is a calm, private social map that helps you capture real moments in the places they belong.
Drop photos, thoughts, and memories where they happened, and watch your personal map grow into a story only you could tell.
Share quietly with friends, or keep things just for yourself; every Note, Beat, and collection is yours to control.
Because the best moments aren’t made for the feed, they’re made to be remembered.
For Those Who Look Closer

Why Cosma?
Your memories aren’t just content, they’re pieces of who you are.
Where mainstream social media turned connection into consumption, Cosma gives it back. Every coffee, every walk, every quiet moment deserves its own place on the map, not a trip to the bottom of a feed.
Private, human, and yours to keep.
