Other products named Arca
These descriptions come from each company's own website, as of October 27, 2026.

Each friend gets AI travel ideas, the group discusses and votes on them in one chat, and the trip is booked through a provider the user chooses. It's a different company from ours, and the similar domain name is a coincidence.
