Triplyfy
A web app that helps travelers generate and customize itineraries using a custom GPT.
Overview
We used an existing custom GPT with traffic to build a trip planner that turns AI-generated itineraries into a flexible, editable tool for real travel use. I led end-to-end UX design, from user research and interface design to product iteration and feature proposals.
