Where teachers, students, and AI think together

OpenSlate is the AI-native classroom. A student can ask a question immediately when they do not understand. A student can also ask in private. The AI tutor shows the teacher what the class does not understand. The teacher improves the question. The AI tutor turns it into a clear answer. This happens in the lesson.

As students ask, OpenSlate clusters every question into a live confusion heat-map. You see what the class does not understand. You make the question clear. Then you send the correct explanation to the class in the lesson.

Ask in private, count for the class
A student asks the AI tutor the moment they are confused. Every private question adds to the class heat-map.
Wait, why doesn't the y-term make it a minimum?
Good question. Along y the surface falls, so it can't be a minimum.
So is that the "saddle" part?
Exactly. Up in x, down in y. That's a saddle.
