How Does Co:Writer Work?

As letters are typed, Co:Writer predicts the intended word with a selection of word suggestions using powerful grammar-smart word prediction. These suggestions can be read aloud by moving the cursor over the words. Selecting the intended word places it into the built-in writing document. For feedback while writing (and after writing) built-in text to speech can be used to read letters, words, sentences, and any selected text. If the microphone is chosen, you can speak and we'll convert your speech into text.

4+ Million Topic-Specific Dictionaries:

Co:Writer has access to a main prediction dictionary (that includes core words) and Topic Dictionaries (that includes topic specific words). Co:Writer can access over 4 million topic-specific dictionaries which are activated based on the writing task.
