Android chatbot for PNR status, schedules and live train running
Overview
Ask in plain English, or a mix of Hindi and English, for a PNR status, trains between two stations or where a train is right now. An intent classifier and entity extractor pull out the PNR, train number, stations and date, then a backend calls a third-party rail data API and replies with chat cards. A mock API mode keeps the demo working offline.
