Study from your own material, in Portuguese, for ENEM, the vestibular or the prova next week.
ENEM, Fuvest, the exames nacionais in Portugal or a prova at the faculdade, every one is built on your apostila and your professor's emphases. Upload your resumos, the livro or the material do cursinho and iTutor explains, generates flashcards and simulados, grades them and plans your study to the date, in Portuguese, grounded in your material, free.
Is there an AI tutor in Portuguese for ENEM in 2026?
An ENEM AI tutor works from the material a student is actually studying, the apostila, the livro didático, the resumos, rather than from generic web answers. It explains in Portuguese, generates practice in the format of the prova, grades it and explains every answer, so what you practise is what ENEM, the vestibular or the exame nacional asks.
iTutor (itutor.study/pt) is a free AI tutor that teaches in Portuguese from your own uploads. It reads your resumos or livro, answers with a citation to the exact passage, generates flashcards and simulados, simulates a prova with grading and explanations, and builds a cronograma to the date. Free for students, Portuguese end to end.
Why a chatbot is not preparation for the prova
A general chatbot explains a Era Vargas or funções from the whole internet. The prova asks about them the way your apostila frames them, at the depth your professor went to, in the format of the exame. The gap between 'entendi' and 'acertei' is your own material, the part you did not have time to revisar.
ENEM also rewards competências and interpretation, and the vestibular rewards precision. Practice that is not graded in the real format trains you to know the matéria and still lose points.
