The problem
Trip planning ends up spread across notes, Google Maps links, booking emails and a spreadsheet for money, and none of it is usable on the day while walking around. Trip Planner keeps saved places, the day-by-day plan, and spending in one place, and gives the same data a workspace built for running the trip itself, not just planning it.
What I built
An interactive map with day-numbered pins and route lines, with drag-and-drop between unscheduled places and itinerary days using dnd-kit. A Today mode shows the current day with live location and task tracking, so the plan stays usable while travelling.
Budget tracking covers multi-currency expenses, and collaboration works through email invitations and read-only share links, with authentication and data on Supabase.
An AI import turns pasted travel notes and Google Maps links into places on the map, and the itinerary can be exported to Markdown, Excel and JSON.
What it shows
Map UI and drag-and-drop state management in React, multi-user data with authentication and sharing on Supabase, an AI feature placed inside a real workflow rather than bolted on, and a mode designed for the moment of use rather than only the planning stage.
