While ETS uses both human raters and the SpeechRater/e-rater, KMF has developed its own AI. It’s not 100% accurate (typically off by 2-3 points in Speaking), but it gives you instant feedback on fluency, grammar, vocabulary, and coherence. For writing, it highlights spelling errors and suggests advanced synonyms.
