🎯 The challenge
Commerce Clinic ran 9 batches of Class 11 and 12 commerce students. Teachers were drowning in WhatsApp doubts after class — typically 80-100 messages per day, with the same questions repeated. Teachers were resentful, students felt ignored, and the founder had no scalable answer.
⚡ The solution
Turned on the CoachPlus AI doubt-resolution feature, trained on the institute's own curriculum and past-paper answers. Students ask doubts in the app; the AI answers instantly with citations to the relevant chapter. Teachers see flagged doubts the AI couldn't confidently answer — usually 10-12 per day instead of 80.
"My teachers don't quit because of after-hours WhatsApp messages any more. Students get answers in 2 minutes at 11 pm. The AI gets it right 90% of the time, and humans handle the rest."
