About us
A modern-day Bụt
In Vietnamese folktales, Bụt (pronounced /buːt/) is a benevolent deity who appears whenever good people are in trouble. We built the Bụt app in that very spirit: an AI health assistant that appears when you worry about your family’s health.
What the Bụt app does
✓A lifelong health record for the whole family: history, allergies, prescriptions, test results — kept in one place, found in one tap.
✓On-time medication reminders and drug-safety warnings, especially for antibiotics.
✓Explains test results and medical jargon in plain words.
✓Shares your record with a doctor only when you allow it — controlled, revocable.
All features are free. Bụt supports doctors rather than replacing them: every diagnosis and treatment decision belongs to a qualified doctor.
