What is Predkey?

  • PredKey is an innovative and improved keyboard
  • PredKey predicts the next word in the sentence and gives the top three suggestions. With a click/keypress you accept the suggested word without fully typing it
  • PredKey works both with ngrams (looking at the last few words) and taking into account the partial word the user already has typed
  • PredKey uses a dictionary of 20,000 most common english words
  • PredKey's algorithm is easy to extend (e.g. learn new words, new ngrams the user often uses)
