About

ChemLens

Features
Read full description

ChemLens turns your camera into a chemistry lens. Point it at any everyday object โ€” a wooden chair, a plastic bottle, a glass cup, a metal coin โ€” 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 โ€ข Object identification โ€” name, category, and a one-line composition summary โ€ข Chemical composition โ€” the main constituents and their estimated percentages, shown as a clean bar chart โ€ข Elemental breakdown โ€” the key chemical elements (O, Si, C, Fe, S, and more) with short, plain-language notes โ€ข Environmental impact โ€” rough carbon footprint, water use, and recyclability estimates โ€ข Material origins โ€” where these materials typically come from and a bit of history โ€ข Suggested reading โ€” curated links (mostly Wikipedia) so you can dive deeper into anything that catches your interest KEY FEATURES โ€ข Scan with your camera or upload a photo from your gallery โ€ข Bilingual interface โ€” English and Simplified Chinese, switchable any time including on the login screen โ€ข Personal scan history with search and material filters โ€ข Bookmark any scan to revisit it later โ€ข Cloud sync โ€” your scan history follows you across devices once you sign in โ€ข Privacy-first camera โ€” the camera is off whenever you leave the Scan tab, so your privacy indicator stays off โ€ข Account control โ€” 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 โ€” 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.
