When it comes to proofreading a PhD thesis, accuracy and attention to detail are paramount. Many students might be tempted to use tools like Grammarly for their proofreading needs, lured by the convenience and the promise of error-free writing. However, relying solely on Grammarly for such a critical task can be a significant mistake. Here are five compelling reasons why you should consider a professional proofreader instead.

1. Grammarly Will Not Comprehend Technical Language

PhD theses are dense with specialized terminology and jargon specific to your field. Grammarly’s algorithms, while sophisticated, are not equipped to understand the nuances of technical language. For instance, in a biomedical thesis, terms like “angiogenesis” or “polymerase chain reaction” are common, but Grammarly might flag them as errors or, worse, suggest incorrect alternatives.

A professional proofreader with expertise in your academic discipline will recognize and understand these terms. They will ensure that your use of technical language is accurate and consistent throughout your thesis. This level of understanding is crucial because even minor inaccuracies can undermine the credibility of your research.

2. Grammarly Struggles with Complex Grammar

Complex grammatical structures are a hallmark of academic writing. PhD theses often involve intricate sentence constructions that convey detailed and nuanced arguments. Grammarly excels at catching basic grammar mistakes but struggles with more sophisticated issues like complex sentence structures, verb agreements, and the proper use of subordinate clauses.

Consider the following sentence:

“While the participants’ responses indicated a general agreement, the nuances of their feedback, which were crucial to understanding the broader context, were often overlooked.”

Grammarly might not flag any errors here, but a professional proofreader would ensure that the sentence flows smoothly and that each clause is correctly used. They can also suggest improvements that enhance clarity and readability without sacrificing the complexity needed for academic rigor.

3. Grammarly Doesn’t Understand Context

Context is everything in academic writing. The meaning of words and sentences can change drastically depending on the context in which they are used. Grammarly lacks the ability to fully grasp the context of your writing, which can lead to inappropriate suggestions and missed errors.

For example, in a historical analysis, the term “revolution” might refer to a political upheaval, a scientific breakthrough, or a significant technological advancement. Grammarly cannot discern which meaning is intended based on context alone. A human proofreader, familiar with your field of study, can understand these distinctions and ensure that your terminology is used correctly and consistently.

4. Grammarly Can’t Provide Constructive Feedback

One of the most valuable aspects of working with a professional proofreader is the constructive feedback they provide. Grammarly can identify errors and suggest corrections, but it cannot explain why a change is necessary or how it improves your writing. This feedback is crucial for learning and improving your writing skills.

A professional proofreader will not only correct your mistakes but also explain the reasoning behind their changes. They can offer insights into better sentence structure, clearer argumentation, and more effective communication of your ideas. This personalized feedback helps you become a better writer, which is invaluable for your academic and professional future.

5. Grammarly Isn’t Human

The most significant limitation of Grammarly is that it isn’t human. Proofreading a PhD thesis requires a deep understanding of academic tone, style, and conventions. A human proofreader brings a level of sensitivity and nuance to the task that an algorithm simply cannot match.

Academic writing is not just about correctness; it’s about conveying complex ideas in a clear, persuasive, and engaging manner. A human proofreader can ensure that your thesis maintains the appropriate academic tone, flows logically, and is engaging to read. They can identify subtle issues that a tool like Grammarly would miss, such as awkward phrasing, inconsistent voice, or a lack of coherence between sections.


While Grammarly is a useful tool for basic grammar and spelling checks, it falls short when it comes to the rigorous demands of proofreading a PhD thesis. The complexity, nuance, and specialized knowledge required for this task are beyond the capabilities of even the most advanced algorithms. By investing in a professional proofreader, you ensure that your thesis is polished, precise, and ready for submission.
