Astra AI is a personal AI tutoring tool. According to the official description, it has been used by more than 10 million people and covers all-subject learning and exam preparation. Based on users' own notes, slides, past exam papers, photos, and other materials, it can automatically build a topic-based study plan and turn it into lessons, quizzes, and simulated mock exams, helping users review only what will actually be tested.
Its main capabilities include: after setting an exam date and adding personal materials, generating a step-by-step study plan tailored to the exam scope; providing multiple learning formats such as quizzes, guided lessons, and automatically generated podcasts; supporting oral exam simulations and timed full mock exams with scoring; allowing users to ask their dedicated AI tutor questions at any time, with the tutor explaining step by step according to the user's level until they understand; enabling users to upload a photo of a question and receive a step-by-step explanation; instantly generating quizzes, flashcards, mock exams, and even podcasts on any topic; providing dozens of interactive apps, including interdisciplinary 3D simulations, visual models, and challenges, and allowing users to create their own learning apps; and increasing motivation through gamification mechanisms such as study streaks, badges, and daily challenges, while tracking mastery on a weekly basis.
In terms of how to use it, the official description says users can get started without credit card registration and setup, and can begin experiencing it for free. After adding study materials such as notes, slides, past exam papers, and photos, Astra AI generates a plan around the exam scope. Users can ask questions on any topic at any time, upload a photo of a question, or directly generate quizzes, flashcards, mock exams, and podcasts.
Applicable scenarios include students preparing for exams (officially described as aimed at middle school, high school, and university students), parents helping their children study and checking progress, and teachers using it in the classroom with a class, creating learning apps, and sharing them with students.

Regarding limitations and commitments: the official description states a guarantee of "improve grades by two levels, or get a full refund," and mentions an average rating of 4.73 stars, about 500 posts per day, and thousands of people posting content daily, but it does not provide specific details of the refund terms. As for the differences from ChatGPT and Photomath, whether there is a free version and the specific pricing, the specific subjects and exam list supported, and the methods of data security and privacy protection, the official text lists these only in the form of FAQ questions without giving specific answers, and no clear information is currently provided.
