Cardify - AI错题本

Take a picture of a wrong question, and it will automatically identify the question and the student's answer, generating a complete analysis and review flashcards. Automatically file by subject and knowledge point, and you can also filter out weak wrong questions and print them with one-click layout.

Cardify is an AI wrong-question notebook designed for students and parents. When you encounter a wrong question, take a photo or select a picture from the album. After confirming the question scope, Cardify will organize it into a clear wrong-question record for easy review and tracking later.

You can use Cardify to:
- Take a photo or import a wrong question from the album
- Confirm the scope of a question to reduce interference from irrelevant content
- View the question, the student's answer, the thinking process, the solution process, and feedback
- Keep the original photo to review the question details at any time
- Organize wrong questions by date, subject, and knowledge point
- Understand which subjects and knowledge points are mainly wrong through the analysis page

Cardify is suitable for K12 students to daily organize wrong questions in homework, test papers, and exercises, and is also suitable for parents to understand their children's recent weak points. We hope that wrong questions are not just taken pictures of, but become learning records that can be reviewed, traced, and continuously improved.

Before using the AI scanning function, Cardify will prompt you to confirm the data processing instructions. The wrong-question pictures and necessary request information are only used for this recognition and analysis request and will not be used to train the AI model.
