ChemLab AI

What happens when you mix hydrochloric acid with sodium hydroxide? Just pick the two substances and find out.

**ChemLab** uses AI to predict what happens when any two chemicals meet, and to solve any chemistry problem from a photo — delivering the balanced equation, observable effects, hazard information, and a full step-by-step worked solution.

**Mix Any Two Substances**
Choose from 36 common chemicals — acids, bases, salts, metals, oxidizers, and organic compounds — and tap React. ChemLab instantly returns the balanced equation, reaction type, observable effects, hazard level, safety precautions, and a surprising fun fact about the reaction.

**Solve Chemistry Problems**
Take a photo of any chemistry question and get a full step-by-step solution — topic, given data, key formula, worked calculations, and final answer. Powered by Google Gemini AI.

**Experiments, Flash Cards & History**
Explore 8 interactive simulations across pH and titration, gas laws, solution chemistry, and electrochemistry — all with live sliders and real-time visualisations. Study with 44 built-in flash cards and revisit saved reactions in your personal history anytime.

**Perfect For**
• High school and university chemistry students
• Anyone curious about what chemicals do when mixed
• Students preparing for exams or lab reports
• Teachers looking for quick, visual chemistry demonstrations

**About Chemical Reactions**
ChemLab covers the reactions found in a standard chemistry curriculum: acid-base neutralisation, redox reactions, precipitation, combustion, and gas-forming reactions. Results are generated by Google Gemini (via Replicate) and are for educational reference only. Never attempt real chemical reactions without proper supervision, safety equipment, and training.

**Privacy First**
All reaction history is stored locally on your device. Photos and substance selections are only sent for AI analysis and are never stored on any server.
