AI tutors
The AI tutors that try to teach across subjects. Several compete with software our publisher builds, so we list those with verified facts and don't rank them. The question that matters is whether a tutor fits the exam a student actually sits.
Our publisher also builds learning software, so we never rank by ad spend or our own interest. System-native tools are listed first; each is read through the Four Mismatches Test.
Listed, not scored
Our publisher also builds learning software in this area, so we don’t score or rank these tools. Each profile gives the verified facts; the judgement is yours.

Frequently asked questions
- What is the best AI tutor?
- It depends on the exam. A tutor built for a US curriculum can be excellent and still teach the wrong syllabus for a Commonwealth exam. Several tutors here compete with software our publisher builds, so we don't rank them: run the Four Mismatches Test against the exam your student sits.
- What is the best free AI tutor?
- Several are free, including non-profit ones. Free and exam-fitting are different questions, though: a free US-curriculum tutor still teaches the wrong syllabus for a local exam.
