Rock Identifier is an AI-powered geology companion from Kawaii, Inc., designed to help curious beginners and rock enthusiasts learn about specimens they find. Users can take or upload a photo to identify rocks, minerals, gemstones, and crystals, with results provided in seconds. The service presents common and scientific names, classifications, physical properties, and explanations of how specimens formed and the geological forces that shaped them. It also offers information about uses and origins, helping turn a quick identification into a field-guide-style learning experience.

Beyond photo identification, Rock Identifier lets users add personal field notes and build a private collection of identified specimens. Its community gallery showcases recent discoveries and allows users to share their own finds publicly or keep them private. The website also offers a free online identifier for those who do not want to download the app. Rock Identifier is part of a broader suite of AI identification apps covering subjects such as plants, birds, insects, mushrooms, and coins.
