Rock Identifier

AI-powered field geology

Identify any rockfrom a photo.

Snap a photo of any rock, mineral, gem, or crystal — Rock Identifier names it in seconds and explains how it formed, what it’s made of, and where it came from.

What you get

A pocket geologist, always with you

Identify a rock, then explore everything about it — properties, formation, and your own notes — all in one app.

Photo identification

Point your camera at any rock and get an answer in seconds — no field guide, no guesswork.

Properties & classification

Common name, scientific name, physical properties, and category — the data a geologist would write in a field notebook.

Formation & history

Trace each specimen back through time: how it formed, when, and which geological forces shaped it.

Field notes

Add your own notes to any identification — conditions, observations, or anything you want to remember.

Personal collection

Build a private cabinet of every rock you’ve identified, with your own notes attached.

Community gallery

Browse rocks identified by other rockhounds — and share your own discoveries publicly or keep them private.

How it works

From photo to rock identification in seconds

Step 01
Take a photo
Capture the specimen in natural light. A clear shot of texture and color is all the AI needs.
Step 02
AI does the geology
Our model reads mineral, texture, and color signatures to identify what you’re looking at.
Step 03
Read the report
Get name, classification, formation, uses, and field notes — written like a real field guide.
