Brilliant learners can ask Koji a math question even when it is not part of their current lesson. Koji interprets the question and routes the learner to relevant instruction or practice. This is available to all web users in the Home tab.
What can learners ask?
Learners can describe a concept, skill, or type of problem in their own words. For example:
- “I need help with quadratic equations.”
- “Why do negative exponents work that way?”
- “Give me practice with triangle similarity.”
- “What should I review before starting calculus?”
Koji uses the request to find a relevant starting point in Brilliant’s math curriculum.
What happens after Koji routes the question?
- Koji identifies the topic. The learner does not need to know the course or lesson name.
- Brilliant recommends relevant instruction or practice. The learner can build the underlying skill through interactive problems.
- Koji stays available during the work. If the learner gets stuck, Koji can respond to what is happening in the lesson, highlight relevant information, and ask guiding questions.
This approach is designed to help learners practice and understand the concept rather than merely copy an answer.
When is a human still useful?
Koji can help learners find and practice a broad range of math topics. A teacher, school counselor, or qualified specialist remains the better resource for formal assessment, graded-assignment requirements, accommodations, or questions about a school’s exact method.
