A single general assistant answers every question in the same tone. Aura splits that into five named characters with their own rooms, colours and jobs: a council that gives you a position rather than a balanced summary, a mentor who speaks in character, a psychologist with a one-tap mood check-in, a teacher who explains a chapter photo or PDF and then quizzes you back, and poets who answer in verse. Rooms don't share context, and the mood log is written to the device, never a server. Hindi, Hinglish or English.
