Questi review
An interactive study assistant for working through questions and exam practice.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Questi is an AI study assistant for students who want help solving academic questions and preparing from course materials. Learners can upload images of problems or textbook PDFs for detailed explanations, then ask follow-up questions in a conversation. Its stated subject coverage spans general school subjects and major-specific work, with particular emphasis on mathematics, physics, and engineering. Web access and an iOS app give it two ways to study, while its tools extend beyond one-off answers into practice and review.
Its strongest fit is interactive, material-based study. Similar problem generation gives learners another question to work through after an explanation, and AI-generated cramming quizzes can draw on textbook uploads. Book Chat and personal library tools support working with saved study material; exam analysis, exam similarity analysis, question review, and essay correction address review and writing tasks. This breadth makes Questi more suited to a study workflow than to a narrow answer lookup, though students who need a different platform ecosystem should weigh its web and iOS availability.
Questi is freemium and offers a free plan alongside Basic, Plus, Super, and Premium. According to the vendor's plans page, Basic is KRW 6,900 per month; the listed tier names alone do not make paid-plan differences easy to compare. Addon T is priced at USD 3.27 per month and includes automatic monthly credit recharge and a 25% discount on additional feature fees. Questi was founded in 2024. Students seeking image and document-based explanations, follow-up help, and exam practice should consider it; buyers who need clear side-by-side paid plan comparisons may prefer to evaluate alternatives before choosing a tier.
