ABC Chemistry AI Tutor STEP-BY-STEP

Ask any chemistry or calculation question in plain language — balancing, mechanisms, stoichiometry, concepts.

Hi! I'm your chemistry tutor. Ask me things like “balance Fe + Cl2 → FeCl3 and explain”, “why is water polar?”, or “find the pH of 0.01 M HCl step by step”.

Your question

🔑 Apni AI API Key — Claude ya ChatGPT (optional)

Agar aapke paas apni Anthropic API key hai (console.anthropic.com se), yahan daalein — Claude key (sk-ant-...) ya ChatGPT/OpenAI key (sk-...) dono chalti hain. AI Tutor seedha aapki key se chalega. Key sirf aapke device par save hoti hai, kahin bheji nahi jaati.
