Yisi AI Education

Yisi is a learning application for A-Level and IGCSE students. It helps learners organise questions, understand mistakes, practise targeted topics, and track progress. Yisi currently focuses on mathematics and economics learning content for the Edexcel and Cambridge examination systems.

1. Photo-based question answering

Students can photograph or upload a question and request an explanation. Yisi may recognise the question, match it with available question-bank content, and show an answer or step-by-step explanation. If a question is not matched, Yisi may use an AI service to generate an explanation. Automatically generated or recognised answers should be checked against authoritative course materials.

2. Smart practice-paper generation

Students or teachers can choose topics, difficulty, examination years, and other available criteria to generate a practice paper and answer materials. Yisi may use learning records and selected knowledge points to support targeted practice.

3. Wrong-question book

Users can photograph or otherwise record a wrong question. Questions created through question answering or learning analysis may also be added to the wrong-question book so that users can review them later.

4. Learning analysis

Yisi can analyse completed papers and practice activity to show knowledge-point accuracy, wrong-question frequency, and progress trends. Students, parents, and teachers may see different views depending on the product feature and the permissions associated with their account.

5. Free access

All currently available Yisi features and learning content are provided free of charge. Users do not need to make a payment inside or outside the app to access available content, and Yisi does not offer subscriptions or paid feature upgrades.

For information about data used by these features, see the Privacy Policy and Personal Information Collection List.
