Platform

See what your students are actually thinking. Not just what they turn in.

The idea

Practice that keeps the thinking with the student.

Students work inside Coach, not in open-ended AI chat. They cannot paste in outside text or generate polished answers without doing the work. Instead, the AI responds to what the student is actually doing: asking questions, offering hints, and guiding revision. The thinking stays with the student.

We are not trying to restrict AI. We are trying to make sure students still do their own thinking when they use it.

AI should support student thinking, not replace it.


For students

What students actually do

Students practice in cycles. Each one follows the same rhythm:

Attempt Feedback Revision Retry Mastery

A student tries a problem. The platform gives them specific feedback. They revise and try again. Over time, skills move from first exposure toward real mastery.

This is not a quiz engine that marks answers right or wrong. The student does the thinking. The platform helps them see where to improve.

For teachers

What you see as the teacher

You get Teacher Decision Support: a daily view of your class that shows you where students are, who is falling behind, and what to do about it.

Instead of reviewing stacks of assignments or guessing who is falling behind, you get clear information drawn from real student work: who to check in with, which skill to reteach, which students to group together.

It does not replace your judgment. It gives you the visibility you need to use your judgment well.

Behind both the student coaching and the teacher insights is Coach Engine, the system that reads patterns in student work, guides coaching, and surfaces what matters most.

Step into the teacher experience

The guided tour walks you through a real teacher dashboard with a class full of sample students. Nothing is simulated. You're looking at the same tools and data views that a teacher would use with a live class, with audio narration along the way.

Here is what you will find inside:

Teacher Decision Support

A daily view of where each student stands: who's struggling, who's improving, and which skills need your attention.

Assignments and student work

See how students move through quizzes, essays, and decision scenarios. Every attempt, revision, and score is visible.

Patterns you can act on

The platform surfaces which students need help, which skills to reteach, and what to adjust before you have to go looking.

Starting point

Built for AP classrooms first

Coach launched with AP Statistics, AP World History, AP US History, and AP Government. These are courses where the stakes are real, the curriculum is clear, and the difference between performing well and truly understanding matters.

More AP subjects are coming. But we started here because AP teachers are the ones who need to see student thinking the most. And their students need genuine practice the most.

Clarifications

What this is not

Not a replacement for you

The platform gives you better information. You still make the decisions about your classroom.

Not open-ended AI chat

Students cannot use it to generate answers on demand. The AI coaches them through the work. It doesn't do the work for them.

Not just a quiz engine

Right answers are not the goal. The platform tracks how students think, revise, and reason. Not just whether they got it right.
