Point your camera at a rock and Geology Toolkit tells you what it is, how it formed and what it is made of, then draws you a labelled pencil sketch of it. One photo, the full story. Powered by a frontier class AI model, it identifies rocks, minerals, crystals, gems and pebbles, explains the formation history behind each one and gives you the geological detail to go with it: Mohs hardness, lustre, chemical formula, companion minerals and more. Whether you're a curious walker who picked up something interesting, a rockhound building a collection, a student preparing for fieldwork or a professional out in the field, Geology Toolkit is a considered field guide in your pocket. What you can do • Identify rocks, minerals, crystals, gems and pebbles from a photo • Read the full formation story: how each specimen formed, over what timescale and in what conditions • Discover the companion minerals commonly found alongside your finds • Turn any find into a labelled pencil field sketch in seconds • Save specimens to your personal field guide with sketches, notes and locations • Get confidence scores and alternative identifications for tricky specimens • Meet a new Rock of the Day every morning, with a daily quiz to test what you've learned • Explore What's Beneath: rock columns for places like the Grand Canyon, layer by layer through deep time Built for serious curiosity • Rockhounds and collectors building a field guide of finds • Geology and earth science students studying mineralogy, petrology and classification • Field professionals needing quick, reliable identification and reference • Educators and parents exploring geology with curious learners • Anyone who's ever picked up a stone and wondered what it was Why Geology Toolkit Most rock identifier apps stop at a name. Geology Toolkit goes further, explaining why a rock is what it is, how it formed and what to look for in the field. Every identification adds to your personal field guide, building a reference you'll return to. Available in English, Spanish, German, French, Portuguese and Japanese. Try it free for 7 days, then subscribe for unlimited identifications, full formation histories, companion mineral data, sketches and an exportable field record. From photo to real geological understanding, one specimen at a time. Terms of Use: https://www.geologytoolkit.com/terms Privacy Policy: https://www.geologytoolkit.com/privacy-policy
