AI tutor

The AI tutor that knows the assignment.

CircleIn's tutor is mapped to each student's actual course. It works from the professor's materials, coaches students step by step on what's due this week, and covers only what the professor has turned on. Developed with support from the National Science Foundation.

MATH 111 · Problem set 4AI tutor
Can you just give me the answer to #3?
Let's get you there. Problem 3 asks you to solve the system by substitution, the method from Tuesday's lecture. Which equation already has a variable on its own?
The second one, y = x + 4.5
Exactly right. Substitute that into the first equation. What do you get when you replace y?
-6x + 6(x + 4.5) = 28
Nice work. Now expand the 6(x + 4.5) and combine like terms. Check the next step carefully, then tell me what you have.
What makes it different

Built around the course, not a topic library

🎯

Mapped to the course

Where your school enables it, the tutor draws on assignments and materials from the LMS. Students get help with the exact homework in front of them instead of hunting through generic content.

🔒

Professor-scoped

The tutor covers what the professor has activated. It keeps students focused on what's due now and reinforces the course instead of replacing it.

🧭

Coaches by default

Hints come first, one step at a time, so students learn the method, check their own work and build the skills the course is grading.

For students

Help the moment they need it, in a few taps

  • Snap and ask: photograph a math problem on mobile, type "help", and get hints one step at a time
  • Generate examples: work through a similar problem with different numbers, then apply the method to the original
  • Share the rubric: paste assignment details so feedback aligns with what's graded
  • AI shortcuts: essay feedback, summaries of chapters and notes, practice questions and personalized study plans
  • Unlimited and always on: no usage caps, on web and mobile, at 3 a.m. or before an 8 a.m. exam
For faculty

See where your class is stuck

  • AI tutor analytics: student activity, the types of questions asked, and engagement over time
  • Course-level trends that show which concepts need another pass in lecture
  • A 15-minute setup loads your syllabus, policies and due dates, so the tutor answers routine questions that would otherwise land in your inbox
  • Your uploads are not used to train other AI models and are not shared with other schools or professors

Five steps that drive the highest usage

When professors make tutor practice part of the course grade, usage reaches 80 to 100 percent.

1

Add it to the gradebook

Count AI tutor practice toward participation. About ten interactions a week works well.

2

Name it in your AI policy

List the CircleIn AI tutor as an approved learning tool in your syllabus and orientation.

3

Show the intro video

A short intro video shows students how to get started.

4

Open with a warm-up

Give students one to three questions to ask the tutor at the start of class.

5

Close with a check-in

Use the last five minutes for practice with the tutor. Most students won't raise a hand to ask.

The AI Tutor Challenge

Try it on your own homework in ten minutes

Log in with your school credentials and ask the tutor one to three questions from one of your assignments. Ask it for the answer outright. Make mistakes like a student would. Then see how it responds.
