Why OpenTrip?
Group travel planning is usually a mess of group chats, spreadsheets, and half-updated maps. OpenTrip keeps the whole trip in one shared workspace:
- See the route — stops on a live map with day filters, weather, and place search
- Own the day — a schedule board per day so timing and transit stay clear
- Spend fairly — expenses, balances, and minimal settle-up transfers
- Decide together — votes, comments, and invites for the whole crew
- Ask the agent — a trip-aware AI companion when you need a second opinion
The seed demo is Japan · Autumn — Tokyo → Kyoto → Osaka, 5 days, 25 stops, and a full expense ledger ready to explore the moment you sign in.
