About Hiero Lens

Hiero Lens reads Egyptian hieroglyphs from a photo or a drawing. Recognition runs in your browser, so nothing you draw or photograph leaves your device. When you correct a sign the camera read, we keep the code it read, the code you chose and where the box sat on the photo, never the picture.
