Then, add it to Chrome, Microsoft Word, Google Docs, WordPress, Android, or Firefox to start improving your writing in real-time. Most of these programs have an add-on that can work directly with these programs.

Another option is to install the mobile or desktop app from the writing assistant. Make sure it is running when you write, so you can get the suggestions as you go.

Once the program is in place, allow it to scan your writing as you write. Take advantage of the suggestions it provides to tighten up your copy and make your writing stronger and easier to read, but always remember this is an AI. You, the writer, have the final say in how something should be read.
