What Makes Kimi Different From ChatGPT and Claude?
ChatGPT has a 128k token limit. Claude Sonnet has 200k. But most students only use the free tier, which has much tighter limits. Kimi AI (created by Moonshot AI, a Chinese company) offers 200,000 tokens on the free tier — no limit on message length.\n\nWhat does 200k tokens mean? It is roughly 600-700 pages of text. That means you can upload:\n- An entire NCERT textbook (usually 200-300 pages)\n- All past JEE or NEET papers from the last 10 years\n- Multiple chapters of a reference book\n\nIn ONE conversation. And Kimi understands all of it.
How to Upload and Use NCERT PDFs on Kimi
Step 1: Go to kimi.ai and sign up with email (free, no credit card).\n\nStep 2: Click "New Conversation" and look for the attachment/upload button (usually a paperclip or "+" icon).\n\nStep 3: Upload your NCERT PDF. Wait 30 seconds for it to process.\n\nStep 4: Ask questions about it:\n- "Summarise Chapter 3 in bullet points"\n- "What are the 10 most important definitions in this chapter?"\n- "Create 20 MCQ questions about Photosynthesis with answers"\n- "Explain the Water Cycle diagram in the PDF"\n\nKimi reads your PDF and answers only based on what is in that document — no hallucinations.
Use Case 1: Analysing Past Papers (NEET/JEE)
Upload 10 years of NEET past papers (1000+ pages) to Kimi. Then ask:\n\n"What are the 20 most frequently tested Biology topics in NEET over the past 10 years?"\n\nKimi analyses all papers and tells you exactly which chapters appear most often. This tells you where to focus your limited study time.\n\nAnother prompt: "For every topic that appears more than 5 times, give me a 1-line summary of what students must know to answer these questions."\n\nYou get a super-focused study guide extracted from actual past papers — this is much better than random study guides.
Use Case 2: Creating Practice Questions From Your Textbook
Upload Class 12 Physics NCERT (all chapters). Ask:\n\n"Generate 50 important MCQ questions from the Electrostatics and Current Electricity chapters with correct answers and explanations."\n\nKimi extracts key concepts from your NCERT and generates practice questions instantly. You get unlimited practice material from your own textbook.
Use Case 3: Comparing Textbooks (NCERT vs Reference Books)
Confused whether your reference book covers everything in NCERT? Upload both PDFs to separate conversations (free — you can have unlimited conversations).\n\nKimi from NCERT conversation: "List all important terms and formulas"\nKimi from reference book conversation: "List all important terms and formulas"\n\nCompare the two lists. See gaps. Know exactly what your reference book is missing.
Tips for Getting the Best Results From Kimi
Be specific in your prompts: Instead of "summarise this chapter," say "Summarise Chapter 5 in bullet points with main concepts, definitions, and formulas."\n\nAsk follow-up questions: "Now explain this point in simpler language for a Class 10 student."\n\nRequest multiple formats: "Give me this in a table," "Create a mind map," "List in order of importance."\n\nVerify important answers: If Kimi says something is on page X, check your PDF. Kimi usually gets it right but double-check critical information.
