College Board framework
Every AP Chemistry skill maps to a unit and topic in the College Board's course and exam description, so sessions match what the exam tests.

AP Chemistry
Pioneered by Stanford AI researchers and learning scientists, Aristotle is the world's first voice-based AI chemistry tutor. Built for the AP Chemistry course and exam, Aristotle has improved thousands of grades over 22% within a week.

Fits your child's AP Chemistry class
Every AP Chemistry skill maps to a unit and topic in the College Board's course and exam description, so sessions match what the exam tests.
Share your teacher's syllabus, textbook, or pacing guide and sessions follow your child's actual AP class.
Aiming for a 5, or just to pass? Aristotle builds the path backwards from your target score and the May exam date.
Features
Talk things through, work side by side, and come back next time to a tutor who remembers where you left off.
Ask questions out loud, hear explanations in Aristotle’s voice, and interrupt whenever you need to.
Aristotle draws steps, diagrams, and images to help you learn visually.
Get practice problems tailored to the exact topics you’re struggling with.
From middle-school math to AP exams to SAT/ACT prep. We also build custom plans matched to state standards and specific courses.
Revisit session summaries, session whiteboards, and uploads in one place.
Aristotle can read and navigate any PDFs and images with the learner. That includes textbooks with hundreds of pages!
We break all subjects down into granular skills, then track mistakes and mastery on each one. Parents can see the whole picture at a glance.
Aristotle remembers every session: what you’ve covered, where you got stuck, how you like things explained. It picks up right where you left off.
