Product preview

Overview
Pi is built around conversation rather than tasks: it asks follow-up questions, remembers context between sessions and leans warm instead of transactional.
It is deliberately narrower than work assistants — no file uploads or heavy coding — which keeps exchanges focused, and voice mode makes it feel closer to a phone call than a search box.
