Co:Writer® Universal app and third-party keyboard gives students easy access to word prediction on iPad, iPad Pro, iPhone, and iPod Touch. Students simply sign in to their Co:Writer Universal accounts to write with their personal settings and vocabulary. ABOUT CO:WRITER UNIVERSAL This version is for schools with a Co:Writer Universal license only. Users without a Co:Writer Universal license must purchase the Co:Writer app. 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 with a swipe. Selecting the intended word places it into the writing document. For feedback while writing (and after writing) built-in text to speech can be used to read letters, words, sentences, and the entire document. 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 - Apple II - Compare and Contrast - Dinosaurs - Grumpy Cat - History of the Peloponnesian War - Mahatma Gandhi - My Dog - Pig Latin - Rolls-Royce Silver Ghost - SpongeBob SquarePants - Tommy (album) - Wonders of the World SPELLING SUPPORT Co:Writer handles the widest range of spelling mistakes through its Flexspell™technology including phonetic spelling and inventive spelling errors (letter omissions, word ending omissions, letter reversals, etc). Examples of how Co:Writer aides with phonetic and/or inventive spelling: Before Co:Writer The blk jargon flu over the bra lfnt. R u hpy to ce me? I no hw to nor the fone. After Co:Writer The black dragon flew over the gray elephant. Are you happy to see me? I know how to answer the phone. GRAMMAR SUPPORT Co:Writer bases its prediction off of proper grammar, and uses its understanding of grammar to accurately predict words within the framework of valid sentence structures. Examples of how Co:Writer aides with grammar: Dogs are furry. (noun, verb, adj.) - When you typed d-o, you get plural noun choices Three very mangy dogs ran down the street. (adj., adv., adj., noun, verb… etc.) - After typing three, very, mangy, you get plural noun choices, then you get plural verb tenses. OTHER FEATURES - Built-in Text to Speech - Export
