AI Chemistry Tutor [Phase 2 — coming soon]
Chat with an AI that has read all 6 official Resource Books AND every English-medium AL Chemistry past paper from 2003 to 2025. Ask anything from "what is hybridisation?" to "explain question 3 of 2024 Paper II" and get an answer cited to the exact textbook page and past-paper question.
Why this is hard to build (the honest version)
- Indexing: 6 textbook PDFs (~1,800 pages total) + 32 past-paper PDFs need OCR (most are scans), chunking, and embedding into a vector store.
- Retrieval: for any student question we need to pull the top-k relevant chunks and pass them to a small chat model (Groq llama-3.1-8b-instant for speed and cost — same backend as tilapia.gpaats.com).
- Citation: answers must say "see Resource Book Unit 6, p. 142" and "see Paper II 2022 Q4" — not just freestyle text.
- Hallucination guard: if the books don't cover something (e.g. an out-of-syllabus theory), the bot must say so rather than invent.
Estimated build: 2 sessions. Cost to run: ~free (Groq's free tier handles thousands of requests/day).
