Why it exists

After a few years of coliving, the spaces start to blur. Which one had the good desks, which one had the kitchen nobody cleaned, which one you would book again without reading a single review. The listing said one thing, the stay said another, and the stay is the part that gets forgotten first.

cotrail is where that memory goes: one entry per stay, written while it is still true.

What’s inside

  • A log of every stay — the coliving spaces you’ve lived in, and what they were really like.
  • Your footprint — every stay on one map.
  • A checklist of hubs — the places you have been, against the ones still on the list.

Where it stands

Coming soon to iOS and Android. The landing page is up at cotrail.co; the apps are in development.
