What Studyh is
StudyH is a browser-based active-learning platform from Brazil that uses AI with learner-provided materials. Its workspace places PDFs, slides, YouTube videos, or text beside notes, formatted writing, drawings, images, and subject-organized flashcards. The service creates summaries, flashcards, and quizzes. Review questions retain a source excerpt and page, and the “Abrir fonte” action returns to that PDF location. StudyH lists more than 800 ENEM questions from 2020 and 2022–2025, with official INEP answer keys and explanations checked against them. Free access includes the board, materials, notes, flashcard review, progress panel, and three ENEM questions daily. Paid features include unlimited ENEM questions, AI tools, lecture recording and transcription for up to five hours monthly, and email support. Essay correction estimates five competency scores in 40-point increments, allows up to five monthly AI corrections on an active plan, and does not rewrite essays. The ABNT editor exports DOCX or PDF. No mobile app coverage is listed.
