Google's Gemini is a general chatbot with a great model. reppX is a live class — with a voice, a whiteboard, and your NCERT / ICSE textbook loaded chapter-by-chapter into the teacher's mind.
Gemini is a tool. reppX is a teacher. When you need to actually finish a chapter — with board work, checkpoints, and notes at the end — reppX is the one.
No. reppX uses GPT-5.5 as the primary teacher, Claude Sonnet 4.5 as fallback, and Gemini 3.1 Pro only for parsing your textbook. The teaching is model-diverse and tuned for pedagogy.
Then decide for yourself. 15 minutes a day on reppX is free — no card, no lock-in.
