Plan together. Split fairly.
Keep your group trips organized — from where you're staying to who owes what.
All your flights in one place
Search 500+ airports by name or code. Save a flight and watch the route appear as a great-circle arc on the map. Paste a confirmation email and AI pre-fills everything — flight number, times, even multi-leg itineraries.
- Airport autocomplete for 500+ airports worldwide
- Great-circle arc routes visualized on the map
- AI import from confirmation emails

Every stay, all in one place

Split costs the way you actually want

- Even, exact, fractional, or by-room splits
- Link expenses directly to flights or lodging
- Forgive a portion — it stays in the record
- Members settle their own splits independently
