Any Rock Identifier names a specimen from a photograph and then, unusually for this category, tells you how much to trust the answer. Upload or take a clear, well-lit close-up against a plain background and the AI returns the most likely rock, crystal, gem, mineral or fossil together with a real confidence score, listing alternatives when a specimen is genuinely ambiguous instead of producing one confident answer every time.
Every result also comes with the simple at-home tests that settle it, namely streak, Mohs hardness and magnetism, so the identification can be confirmed rather than taken on faith, and so you gradually learn to identify specimens without the tool.
Results link into a field guide of 130 stones, each with real photographs and coverage of formation, properties, look-alikes and value, plus ten look-alike guides for the pairs that catch people out, such as pyrite against gold and jade against aventurine, and seven how-to guides on the tests themselves. The project publishes its accuracy results openly, including the misses. The first three identifications are free; Pro adds unlimited identifications, value and rarity estimates, authenticity checks, care guides and a full downloadable report.
