LONDON -- The year 2016 is the 400th anniversary of playwright William Shakespeare's death, and the anniversary is being commemorated in many ways -- from performances of all his plays to musical concerts to academic conferences.

But the strangest so far is an app for mobile phones launched Thursday, which allows users to "text like the Bard."

The free app is called ShakeSpeak and can be downloaded onto digital devices. It uses predictive keyboard technology to complete sentences in the manner of Shakespeare.

The app has been developed by SwiftKey, a technology company founded in 2008, as part of a tourism campaign for London.

Technicians at the app developer SwiftKey examined the Complete Works of William Shakespeare to design ShakeSpeak. Users wishing to convincingly adopt a Shakespearean tone to their texts can use "thou", "thee", and "thy."

The predictive technology in the app will do the rest, to produce fake Shakespeare text.

For instance, writing "To be" will prompt the app to complete the sentence with "or not to be, that is the question," or "All the", which is completed as "world's a stage, and all the men and women merely players."
