Since artificial intelligence is becoming more sophisticated by the day, you may be curious if Grammarly can replace an editor. I run Grammarly Pro on blog posts and use it as a final check for the documents I proofread and copyedit for clients. I’m familiar with an editor’s role, so I can tell you if Grammarly is a suitable substitute for an editor.
Grammarly can’t replace an editor. Although it’s an excellent tool for refining writing, it doesn’t perform editing tasks like improving a document’s content, structure, pacing, or flow. Grammarly is best used to detect minor errors and make writing more clear, concise, and compelling.
Let’s explore an editor’s role versus Grammarly’s role to understand why Grammarly can’t replace an editor.
Can Grammarly Replace an Editor?
I don’t think Grammarly can replace an editor.
When people talk about editors, they’re usually referring to developmental editors. In the traditional editorial process, these editors perform the first stage of editing: developmental editing.
They have the license to make significant changes to a piece of writing.
However, we have one other kind of editor with the creative freedom to make substantial alterations: line editors. They perform the second stage of editing, which, not surprisingly, is known as line editing.
In this article, I’ll discuss why Grammarly can’t replace developmental editors or line editors.
Developmental and line editors perform in-depth edits that take longer than copyediting or proofreading.
Furthermore, these extensive edits are more subjective than copyediting and proofreading.
Software like Grammarly isn’t good at performing subjective operations.
These kinds of tools perform better on objective tasks where there’s a right or wrong way to do something.
Before going further, let’s make sure we’re on the same page with editing terminology and understanding the editorial process.
Understanding the editing stages will help you grasp why Grammarly can’t begin to replace a developmental or line editor.
The traditional editorial process has four phases:
- developmental editing (aka structural or substantive editing)
- line editing (aka content or stylistic editing)
- copyediting
- proofreading
What Do Developmental and Line Editors Do?
Developmental and line editors carry out the first and second steps in the editing process.
The Role of a Developmental Editor
Developmental editors consider the whole document.
Their main goal is to improve the content and structure of writing.
They may reorganize, add, or delete large chunks of text.
These editors ensure that the writer addresses all the main points and that the writing makes sense from a reader’s perspective.
When editing a work of fiction, they’ll also consider elements like pacing, plot, character development, and setting.
The Role of a Line Editor
Line editors address issues at the paragraph level and major problems at the sentence level.
Their primary goal is to enhance the language of a text, making it clear and consistent in style and tone.
They may add, delete, or rework sentences within paragraphs.
These editors ensure the text flows smoothly from one idea to the next and note any points that need further explanation.
Line editors will also verify that the language is a good match for the intended audience.
What Do Copy Editors and Proofreaders Do?
As mentioned, I’ll be focusing on developmental and line editors.
However, I’ll briefly explain the role of copy editors and proofreaders so you have the whole picture.
A Copy Editor’s Role
Copy editors work on issues at the sentence level.
Their primary objective is to make a document clear, concise, and consistent.
They also correct punctuation, grammar, capitalization, spelling, and formatting mistakes.
A Proofreader’s Role
Proofreaders work at the word level.
Their main goal is to correct any remaining errors in grammar, capitalization, punctuation, spelling, and formatting.
They also look for missing or repeated words and wrong word choices (e.g., wretch vs. retch).
Now that we know who does what, let’s see why Grammarly can’t replace a developmental or line editor.
What Does Grammarly Do?
Two versions of Grammarly are available for individuals: Grammarly Free and Grammarly Pro.
Grammarly Free checks for spelling, grammar, and punctuation mistakes.
Given what Grammarly Free offers, it can help you proofread a document.
However, it can’t replace a proofreader because it doesn’t do everything a proofreader does, and it lacks the accuracy needed to be a good substitute.
Grammarly Pro provides you with additional benefits:
- basic checks for consistency in punctuation and spelling
- plagiarism detection
- AI-generated text detection
- recommendations to enhance clarity, fluency, engagement, and delivery of writing
Clarity recommendations ensure your writing is free of ambiguities.
Fluency suggestions make sure your writing sounds natural, like that of a native English speaker.
Engagement advice pertains to using a variety of sentence structures and avoiding overused words.
Delivery pointers ensure your writing sounds polite and confident. It identifies the tone of your writing, ensures the formality level is on point, verifies that you use inclusive language, and flags outdated terms.
Considering what Grammarly Pro provides, it can help you copyedit a document.
However, it can’t displace a copy editor because its algorithm isn’t sufficiently comprehensive or accurate. I penned a post about Grammarly’s precision if you’re interested in knowing more.
Why Grammarly Can’t Replace a Developmental Editor
You probably understand why Grammarly can’t substitute for a developmental editor now that you know what these editors do.
To recap, Grammarly doesn’t perform the tasks of a developmental editor, which include the following:
- addressing the overall structure and content of writing
- reorganizing paragraphs
- ensuring the writer has sufficiently discussed all their main points
- handling issues like character development, plot holes, or pacing (when working on fictional texts)
Why Grammarly Can’t Replace a Line Editor
It’s also clear why Grammarly can’t sub for a line editor either.
Grammarly doesn’t handle the duties of a line editor, which include the following:
- adding and deleting sentences
- reworking language to ensure clarity and consistency in style and tone
- checking for transitional phrases or indicators that a message or story flows well
- preserving the writer’s voice—the unique way they express themselves
A writer’s voice reflects their heart and personality.
Grammarly is limited in how much it can ensure the tone of writing is on point. It helps with the level of formality and adjusts writing to fit one of several preselected genres. But these genres are broad.
Editors Chat with Clients, but Grammarly Doesn’t
Developmental and line editors communicate with the writer to ensure they understand the author’s style and goals.
But I have yet to witness a conversation between Grammarly and a writer about details like their target audience and the tone they’re trying to strike.
Writers who collaborate with editors usually go through many rounds of editing.
The editor makes suggestions, which the writer implements. Then, the document is sent back to the editor for another round of recommendations—rinse and repeat.
So the answer to whether Grammarly can substitute for a developmental or line editor is a resounding no.
That kind of work isn’t within Grammarly’s scope.
I authored an article about what Grammarly can and can’t do if you’d like more details about this software.
Frequently Asked Questions
Is Microsoft Editor better than Grammarly?
Based on my May 2026 testing, Microsoft Editor wasn’t as effective as Grammarly. I compared Microsoft Editor, Grammarly Free, and Grammarly Pro and found that both versions of Grammarly significantly outperformed Microsoft Editor.
Can you use Grammarly as an editor?
Grammarly can’t replace an editor because it isn’t built to handle the tasks that developmental and line editors perform. It isn’t advanced enough to substitute for a copy editor or proofreader either, but it can help with some of those duties, like fixing minor mistakes and making writing more concise, clear, and compelling.
Can ProWritingAid replace an editor?
ProWritingAid can’t replace an editor since it doesn’t perform editing tasks. And although it can’t replace a copy editor or proofreader either, it can assist with some of the edits they perform, like correcting minor errors and making a text clear, concise, and engaging.
Is Grammarly the best editor?
Many writers consider Grammarly and ProWritingAid to be among the best “editing” tools. Which one is best depends on what kind of writing you need help with and what you want most from editing software. People generally prefer Grammarly for nonfiction documents and ProWritingAid for works of fiction.
I put the word editing in quotes because Grammarly and ProWritingAid assist us with copyediting and proofreading, not with editing.
Grammarly is a better investment if you need help polishing a nonfiction document. It has one of the most accurate algorithms among popular writing tools.
ProWritingAid is especially helpful for improving fiction. It considers dialogue tags and pacing and gives more detailed writing recommendations.
Should I use Grammarly to edit my book?
Grammarly is an excellent software for polishing a book manuscript, but it can’t substitute for a proofreader or an editor. That being said, it will help you eliminate minor mistakes and make your writing more clear, concise, and engaging. However, Grammarly can’t assist you with editing tasks like improving your book’s content, organization, pacing, and flow.
I hope this article has helped you understand why Grammarly can’t replace an editor.
Best wishes to you!
“A dog has no use for fancy cars or big homes or designer clothes. Status symbol means nothing to him. A waterlogged stick will do just fine. A dog judges others not by their color or creed or class but by who they are inside. A dog doesn’t care if you are rich or poor, educated or illiterate, clever or dull. Give him your heart and he will give you his. It was really quite simple, and yet we humans, so much wiser and more sophisticated, have always had trouble figuring out what really counts and what does not. As I wrote that farewell column to Marley, I realized it was all right there in front of us, if only we opened our eyes. Sometimes it took a dog with bad breath, worse manners, and pure intentions to help us see.”
