Grammarly's algorithms flag potential issues in the text and make context-specific suggestions to help with grammar, spelling and usage, wordiness, style, punctuation, tone, and even plagiarism.
Grammarly is a tool that helps writers, and it offers some AI functions, but I have yet to use them. Expecting AI to determine a topic or provide a complete overview of that topic leaves the author in the position of not being an author.
If, in order to be an author, you would have to be a perfect speller, always with perfect punctuation and perfect sentences, then authors wouldn’t need editors.
Editors analyze the clarity and flow of your writing, ensuring that ideas are communicated effectively and smoothly. They help improve sentence structure, paragraph transitions, and overall readability.
