Cognii

Cognii offers a conversational virtual learning assistant that reads students' answers written in their own words, scores them and gives tutoring feedback. It is sold to K-12 schools, universities and corporate training teams.

Instead of multiple-choice questions, students type short open responses and get immediate assessment with hints, then try again until they master the concept. The assistant holds a back-and-forth conversation to guide them toward a complete answer, and they can use it at any time.

Educators author the assessments, spend less time grading short essays and see analytics on how each student is learning. The product line covers a learning platform, assessment platform, analytics and several integration options for existing course systems.
