AI stone tag suggestions

The app can suggest candidate stone tags from a photo using AI.

  • AI suggestions are candidates only and do not guarantee accurate identification. Please make the final judgment yourself.
  • The AI feature has a monthly usage limit. If you reach the limit, please wait until it resets the following month.
  • Choosing a photo where the stone is large and clearly visible tends to produce better candidates.

Location and spots

Allowing location access makes it easier to see spots near you and to set the location when posting. You can change this anytime in your device settings.

  • When publishing a spot, please make sure it is a collecting site or shop that is safe to share.
  • Do not publish the location of private property or restricted areas. Please also review our Community Guidelines for collecting etiquette.
