Troubleshooting chat
01 / 04The problem
When something breaks at home, people don't know whether it's a five-minute fix or a job for a professional, and nobody wants to install an app to find out.
02 / 04My role
- Built the PWA and its four-mode chat input
- Built session history and the contractor handoff
- Integrated the chat API
03 / 04Chat
The chat keeps a real session: describe a blank TV screen and get a structured, numbered answer, then keep asking follow-ups in the same thread, with a history sidebar of past sessions. All four input modes live in the same chat input on desktop and mobile.
