Trip planning between friends usually dies in the group chat: links everywhere, screenshots nobody can find, and no one quite sure who booked what. I kept running into this on my own trips, so I built the thing I wished existed: one shareable trip with a leader, travellers, and AI agents that quietly do the legwork.
I got to design and build all of it myself, which was a treat: the trip data model, the agent integrations, reminder scheduling, and the marketing site. Agents are wired through Manage-agent flows, and travellers get their reminders without needing an account.
The part I underestimated was trust. Generation turned out to be the easy bit. Getting myself comfortable letting agents act meant every action is scoped, logged, and reversible, and the leader always has the final say.
