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

  1. Step 01

    Take a photo

    Capture the specimen in natural light. A clear shot of texture and color is all the AI needs.

  2. Step 02

    AI does the geology

    Our model reads mineral, texture, and color signatures to identify what you’re looking at.

  3. Step 03

    Read the report

    Get name, classification, formation, uses, and field notes — written like a real field guide.
