Every part of getting a group to converge on one trip.
Coordination is the actual hard problem - not the map. These are the five capabilities that carry a group from a scattered chat to one shared, paid-for, up-to-date plan.
Disruption detected - Priya's return train was rescheduled. Whole group's itinerary adjusted automatically.
The four-stage flow, in depth.
Each stage removes a specific way group trips usually break down.
Gather without the poll thread
Dates, budgets and preferences come in from every traveler through a single structured invite - not a running tally in the group chat that nobody can read.
One plan from many constraints
The shared itinerary is generated to fit the group's real overlap of dates, budgets and interests, with per-person variations where they diverge.
Fair math nobody has to check
Shared and individual costs are separated, split fairly, and tracked - so who owes what and who has paid is never in question.
The whole group moves together
When one traveler is disrupted, the plan is re-solved for everyone affected at once, and the group is told what changed.
