Coach Pen vs ChatGPT
Instant — but it over-scores and writes it for you.
ChatGPT is fast and fluent and can sketch feedback on an essay. But studies show it over-scores writing, misses penalties like under-length and off-topic responses, and will happily write the essay for you. Coach Pen marks to the calibrated exam rubric, coaches your own words, and never ghost-writes.
