The Prisoners Keyboard is the first iOS keyboard built for creative writing.

Based on the Prisoners Constraint, an Oulipian writing game, the Prisoners Keyboard lets you remove particular letters from appearing at all.

This empowers you to create lipograms, writing in which a particular letter or group of letters is avoided. For a classic example of lipograms in action, check out Christian Böks Eunoia.

The Prisoners Keyboard does not collect any information about you and doesnt have the ability to record what you type.

The Prisoners Keyboard is a poems.io joint and made with love by Nick Barr.
