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.

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.

A small sampling of the variety of topic dictionaries: ✔ America's Cup ✔ Compare and Contrast ✔ Dinosaurs ✔ Grumpy Cat

I've found the page that gives payment information. they're are other tools also. when you go to create account then it will ask you for a key code to sign in, you will then click on 7 day free trial this will give you access to the app. it's not a bad app I guess but if your really interested in this app and its functionality then you'll need to purchase a plan monthly. not bad prices either starts a 3.99 a month and up.

I absolutely agree with the other commenters. I've reached out to these guys on Facebook. And other platforms and they're not responding. If they're not going to make their product available to the public sector, then why is it on the edge store?
