Example use cases
Filter low-quality chatbot responses
“Before we store these AI-generated customer support replies in our knowledge base, can you run a quality check on each one to make sure the answers are actually accurate and complete — flag any that don't pass so we can review them manually?”
Benchmark LLM answer quality
“I'm comparing two different language models and I have 50 question-answer pairs from each — can you score all of them for quality so I can see which model is giving better, more accurate responses overall?”
Validate AI tutor answer accuracy
“We have a set of student questions paired with answers generated by our AI tutoring system — can you judge whether each answer is correct and adequately addresses what the student asked, so we can catch any misleading explanations before students see them?”
