Exam season in Brazil is relentless. Each year vast numbers of students prepare for the ENEM and other entrance exams, and the single hardest habit to build across that long runway is steady, daily revision. Descomplica and Google wanted to adapt Descomplica’s teaching into a voice experience that asked for very little effort but rewarded showing up every day.
As Senior UX Designer I developed the mobile Google Assistant experience, working closely with the conversational designer, alongside a senior UI designer and a product manager. The brief was for the experience to meet the student wherever they were: listening hands-free on a Google Home, sound-only through headphones on the move, or screen-only when playing audio was not an option. My part was making the on-screen side hold its own across that range, carrying the whole session when the sound was off and staying in step with the spoken flow when it was on. The work was in the restraint: short prompts, a clear read at a glance, and a rhythm that held whether you were listening, glancing or reading.
The core idea was a daily schedule built to form a habit. A themed week ran from a deliberately tough “Creepy Monday” through to a gentle “Zen Sunday” of soft skills and emotional resilience, with five fresh questions each day and an onboarding “tasting” series pitched at just the right difficulty, so first-time users felt capable rather than caught out. The whole loop, log in, answer, see or hear your result and leave, ran in under two minutes. That discipline was the design: a fast, consistent dose of value that respected a stressed student’s time and attention.
The Google Assistant team described it as one of the smoothest flows they had sponsored. The product met its launch goals before evolving toward lead generation for the wider Descomplica platform.
