Co:Writer® is a writing tool that aids with phonetic/inventive spelling, grammar, and topic-related vocabulary. Co:Writer has been a trusted friend to writers and communicators for decades (tracing its roots back to the days of the Apple II in the late 70s).

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 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.

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

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
1. The blk jargon flu over the bra lfnt.
2. R u hpy to ce me?
3. I no hw to nor the fone.
After Co:Writer
1. The black dragon flew over the gray elephant.
2. Are you happy to see me?
3. I know how to answer the phone.

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:
1. Dogs are furry. (noun, verb, adj.) - When you typed d-o, you get plural noun choices
2. 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.

- Built-in Text to Speech (swipe prediction guesses to hear before selection)

-US dictionaries and US voice only. Please see separate versions for British English and Canadian English.

Customer Reviews


My daughter is dyslexic. This app is wonderful for her writing. I love that she can see and hear the suggested predictive text. My only question is: Can we print without the co:writer header? (She's only 8 so printing directly from the app is a great feature.)

Only other comment is that the voice could be improved. I hope Apple incorporates this functionality into their mail, pages, etc applications some day soon. It's great to be able to output to email but would be wonderful to have right within the mail app itself.

Also, we tested this against other apps and it was the clear winner as far as recognizing phonetic spelling. A nice additional feature would be definitions and help with confusable words (too, to). My only hesitation with suggesting additional functionality is that I really appreciate the very simple interface which has proven ideal for an 8 year old.
Thank you!


I am an Occupational Therapist working in an elementary charter school. I work with a 3rd grader who can not write, due to extremely poor spelling. He has an IQ of 136. His writing appears to be random letters. He has worked with Co:Writer twice before in OT. Today he used Co:Writer to independently type an original 7 sentence paragraph, making only 1 error. It brought tears to my eyes. I have never seen such a transformation. Our principal is ordering Co:Writer on all 4 of our special education iPads. More than worth the $19.99!
