Geology Kit: Rock Identifier

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.

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.
