Meet Cal, an AI tutor for students in grades 7–12, built by a teacher who spent thirty years in the classroom.
Cal will teach your child how to do their homework—it won’t do it for them.
Cal works from your child’s actual courses — their syllabus, their review sheets, the assignment set this week. A grade 7 meeting AI for the first time gets a tutor that will explain a concept six different ways and still won’t write the paragraph. A grade 12 gets full mock exams in IB, AP or Ontario formats, and handwritten work marked from a photo. For a technical account of how it works, visit The Architecture.
"I designed Cal to be the tutor I wanted for my own students: one that values the struggle of learning over the convenience of a quick answer."
— Andy Moore, 30-year teacher of IB Global Politics, History, and English at Ashbury College in Ottawa, Ontario.

Parents come to us for three different reasons:
“My child is about to start using AI.”
The first AI your child uses will teach them what AI is for. Cal makes that lesson the right one. Grades 7–8.
“My child needs to build real study habits.”
Where students quietly stop understanding and start coping — and where Cal changes method until the idea lands. Grades 9–10.
“My child is heading into IB, AP or Ontario exams.”
Mock exams in IB, AP and Ontario formats, built from your child’s actual course documents. Grades 11–12.
