Plain UI design & app screens

Plain is a customer support tool built for modern product and engineering teams, offering a fast, developer-friendly help desk. It targets companies that want support workflows integrated with their stack rather than a heavyweight legacy ticketing system.

The interface is clean and keyboard-driven, with a unified inbox, threads, and tight integrations. Its conversation views, customer context panels, and minimal, precise aesthetic make it a strong reference for modern B2B support tooling.
