A study partner that actually teaches
Kappa is built for one job: getting you genuinely ready for AI evaluation work, not just through the next page.
Explains Any Concept
From rubric atomicity to reward hacking, Kappa breaks down hard ideas in plain language, then checks that they landed.
Works Through Examples
It walks you through real evaluation scenarios, the same kind of judgment calls the work demands, one step at a time.
Connects Across Modules
Kappa links related ideas, so a question in Level 1 can preview where the concept returns and deepens in Level 2.
Quizzes and Checks Recall
Ask Kappa to test you. It turns passive reading into active recall, so you walk into the assessment ready.
Meets You Where You Are
On the dashboard, inside a module, or prepping for the exam, Kappa adapts and opens with what is most useful right now.
Grounded in the Curriculum
Answers stay tied to the actual course content and point you to specific sections, so you can trust what you learn.
Named after the measure of agreement
Cohen’s Kappa is a statistic that measures inter-annotator agreement: how closely two evaluators agree when they rate the same work, corrected for the agreement you would expect by chance. It is one of the core tools professional evaluation teams use to confirm their people are calibrated to the same standard.
The name fits. Kappa’s whole job is to help you reach agreement, first with the standards the curriculum teaches, and then with the bar that real evaluation work sets. Fittingly, Cohen’s Kappa is itself a topic you study in Level 2.
My job is to help you reach agreement with what the curriculum teaches, and eventually with the standards your future platforms will expect.

Is Kappa just a generic chatbot?
No. Kappa is built on a state-of-the-art large language model, but with a custom knowledge layer and a teaching personality designed specifically for AI evaluation.
