Type a message, see it as a goldfish
Type a message and see it the way a goldfish would on a phone at arm's length: blurry, and in its own colours. A goldfish sees about 21 times less detail than you. Pick another animal, then save the card. Your words never leave your device.

A simulation made from published eye studies. Not what the animal feels.
How does a goldfish see words?
A goldfish sees about 21 times less detail than you. Up close the letters melt into soft blobs, and its colours are not quite yours.
Why do the colours change?
Each animal has its own set of colour types in its eyes. The card swaps your colours for the ones the animal would see, from studies of its eyes. For a dog, red and green turn into the same khaki.
Is my message private?
Yes. The card is drawn in your browser. Nothing you type is sent anywhere, and nothing is kept after you close the page.
