Case study

Gabarito AI.

An AI study console that turns a PDF exam syllabus into a study plan, flashcards and annotated practice questions.

The problem

Studying for Brazilian civil-service exams means turning a dense, dozens-of-pages syllabus into an actionable study plan — manual, repetitive work that is easy to abandon.

What I built

An AI study console: upload the official syllabus as a PDF and the app generates a study plan, spaced-repetition flashcards (Leitner method) and annotated practice questions using Claude, with auth and persistence on Supabase.
