HocThem.app is an AI tutor for Vietnamese students, helping to explain 9th grade math problems step by step and closely following the textbooks that the students are studying. Instead of just providing answers, the application guides how to analyze the problem, choose methods, present solutions, and check results, helping students understand the essence of the problem and do similar exercises on their own.

The product addresses a common issue for parents and students: the child gets stuck on homework in the evening, has no one to explain immediately, or searches online but finds solutions that do not follow the curriculum, notation, and presentation used in class. With HocThem.app, students can take a picture or enter the problem, select the textbook they are using, and then receive step-by-step guidance in Vietnamese, easy to understand and appropriate for 9th grade math.

Main features include: explaining math problems step by step; closely adhering to the content of the textbooks; searching in a library of 311 textbooks for grades 1–12; practice tests and review for entrance exams to 10th grade; asking follow-up questions to clarify steps not understood. Students can also request hints instead of complete solutions, fostering thinking instead of simply copying answers.

HocThem.app is for 9th grade students who are reviewing, parents who want to support their children, and teachers who need tools for quick explanations of specific types of problems. Users can directly access the web, try it out immediately without creating an account; then log in to save their learning history and continue practicing.

The difference is the experience designed specifically for Vietnamese students: following the textbooks, explained in natural Vietnamese, focusing on the reasoning process and review for the 10th-grade entrance exam, rather than just giving quick answers or generic solutions.
