Customer email clarity assessment
“We're about to send this email to our customers explaining a policy change. Can you check the readability and let me know if the language is simple enough that most people will understand it without confusion?”
Educational content grade level verify
“I'm creating study materials for middle school students. Can you test this passage and tell me what grade level it's written at, and whether it's appropriate for 13-year-olds or if I should adjust the complexity?”
