What WritingViper does
WritingViper is an app that runs on Windows machines to interact with Microsoft 365 Word with Copilot (either a Microsoft 365 Premium subscription, or a Microsoft 365 subscription with Copilot Pro). It will scan open documents in Word to allow you to establish what kind of story you want to tell and what kind of feedback you wish to have. You can tailor the app to be gentle and simply guide you to a better manuscript, all the way to having the app be brutally honest and give you tons of nitpicky and critical notes about your writing.
WritingViper is just a tool that adds notes to your document. It does not edit anything, change anything, nor does it take any of your work and train any LLM or other AI content on your writing. It is simply an app that interacts with Word to have Copilot provide the feedback you desire.
You stay in Word. WritingViper handles the structure, prompts, and consistency so Copilot can focus on the work.
How it works
Download WritingViper (it's free!). Double-click on the .exe file (if you still have the .zip file, unzip it first and save the .exe file where you will find it easily). If Word is not yet open, open it. Have the app scan your open documents in Word. Then go to the tab of the file that you want to have it review, and follow the steps to have it look through your manuscript.
WritingViper does not write anything for you! You must be your own writer. What WritingViper does is act as a beta reader and a line editor that you tell it to be. It just provides notes. It will never alter your writing, so you choose which feedback from WritingViper you want. You can designate the beta reader to be one from your genre who knows everything about the setting, or have your beta reader be someone who has never picked up a book in the genre and will have more questions than normal. Want your line editor to be someone who ensures your language is time/setting accurate or someone who makes sure you don't use too many cliches and overuses certain words? All of these are settings you can adjust in WritingViper to get the type of feedback you want to see.
Since Copilot for Word does not allow any outside interaction, there are some manual steps you will need to do to make this work. WritingViper will give you a prompt to put into Copilot, and Copilot will provide text that you copy back into WritingViper's UI. Then WritingViper will add the notes to the document for you. Continue until you get to the end of the document. Unfortunately, this is free software, and Copilot is still a closed-off environment, so you get what you pay for with this app!
