ChemLens turns your camera into a chemistry lens. Point it at any everyday object — a wooden chair, a plastic bottle, a glass cup, a metal coin — and ChemLens identifies what it is and shows you the materials, elements, and environmental footprint behind it. Curious students, science teachers, and anyone who loves learning will find ChemLens a friendly way to connect the chemistry they study with the objects they touch every day. WHAT YOU GET FROM EACH SCAN • Object identification — name, category, and a one-line composition summary • Chemical composition — the main constituents and their estimated percentages, shown as a clean bar chart • Elemental breakdown — the key chemical elements (O, Si, C, Fe, S, and more) with short, plain-language notes • Environmental impact — rough carbon footprint, water use, and recyclability estimates • Material origins — where these materials typically come from and a bit of history • Suggested reading — curated links (mostly Wikipedia) so you can dive deeper into anything that catches your interest KEY FEATURES • Scan with your camera or upload a photo from your gallery • Bilingual interface — English and Simplified Chinese, switchable any time including on the login screen • Personal scan history with search and material filters • Bookmark any scan to revisit it later • Cloud sync — your scan history follows you across devices once you sign in • Privacy-first camera — the camera is off whenever you leave the Scan tab, so your privacy indicator stays off • Account control — full account-delete option built right into Settings EDUCATIONAL, NOT A LABORATORY ChemLens is a learning tool, not a chemical analyzer. Every result is the AI's educated guess from a single photo — useful for sparking curiosity and reinforcing classroom topics, but not a substitute for lab analysis, safety information, or medical advice. The model is told to be conservative, and we always show you the source disclaimer.
