InstantTutor is a school-trusted AI study companion, aligned to major exam boards, designed to support students with their homework while keeping parents informed and in control. InstantTutor helps your child understand difficult concepts step by step, rather than simply giving answers.

Your child can type a question or take a photo of their work to receive instant, age-appropriate guidance. InstantTutor also gives parents visibility into how support is being used. You can see where your child is asking for help, which subjects they find most challenging, and where they may need extra support. As part of the weekly progress reports you receive, the app also suggests questions you can ask your child to spark meaningful conversations about their recent learning. Students can also choose to share their activity with teachers, giving teachers valuable insight into where support is needed and reducing the pressure on students to speak up in class.
