Writing in English as a second language can be incredibly rewarding—but it’s also full of challenges. From confusing prepositions and article usage to sentence flow and academic tone, ESL students face a steep learning curve when producing formal academic work like essays, research papers, and theses.
Proofreading tools can help bridge that gap.
These tools are not magic fixes, but they can play a powerful supporting role in your writing process. They catch typos, flag awkward grammar, suggest style improvements, and even explain your mistakes—helping you become a stronger, more confident writer over time. For ESL students, they offer both correction and education.
But here’s the catch: not all proofreading tools are designed with academic writing in mind. Some may overcorrect, misinterpret your meaning, or turn formal arguments into casual chat. Others are better suited for emails or blog posts than a carefully argued thesis chapter. That’s why this article walks you through which tools work best for ESL students writing academically—and how to use them wisely.
Whether you’re polishing an assignment or preparing a master’s thesis, this guide will show you how to use technology to improve clarity, accuracy, and academic style—without losing your unique voice.

Proofreading tools have come a long way. Today’s grammar and style checkers use artificial intelligence to detect common errors, offer smarter suggestions, and even analyse tone. For ESL students, this technology can be incredibly useful—especially during the revision stage of thesis or essay writing.
What Proofreading Software Can Do:
- Catch basic grammar errors
Most tools reliably flag missing articles, subject-verb agreement issues, misused prepositions, and punctuation mistakes. - Spot spelling and word misuse
ESL writers often confuse similar-looking or similar-sounding words. Tools can highlight incorrect word choices like “affect” vs. “effect” or “advise” vs. “advice.” - Identify awkward phrasing
Tools like Grammarly or Hemingway can suggest simpler ways to phrase your sentences, helping you write more fluently. - Support learning
Many tools explain why a suggestion was made, allowing you to understand your mistakes and avoid repeating them.
What Proofreading Software Can’t Do:
- Understand your meaning or argument
No proofreading tool can truly grasp your thesis or the subtle differences between ideas in an academic paragraph. - Fix structural or logical issues
They can’t tell you if your paragraph makes sense, if your claims are supported, or if your citations are relevant. - Apply academic style perfectly
Tools may push you toward more casual writing or miss discipline-specific conventions. For example, they might try to “simplify” academic terminology that should be retained. - Replace human feedback
Ultimately, tools are a helpful first draft companion—but for serious academic documents, a professional proofreader or supervisor is still essential.

Best Proofreading Tools for ESL Academic Writers
There’s no shortage of proofreading tools online, but for ESL students working on academic texts like theses and dissertations, not every tool is up to the job. The following tools stand out for their ability to support clarity, catch grammar issues, and improve academic writing style.
Grammarly
Visit: https://www.grammarly.com
Grammarly is one of the most popular writing tools among ESL students. It checks grammar, punctuation, and sentence structure in real time. Its explanations help learners understand their mistakes rather than just fix them.
- Best for: Grammar correction, basic style suggestions
- Caution: Can overcorrect or “simplify” academic writing to sound informal
- Pro tip: Use the premium version with academic tone settings, but always double-check its suggestions for clarity and appropriateness.
QuillBot
Visit: https://www.quillbot.com
QuillBot helps rephrase awkward sentences and improve fluency, which is especially useful if you’re translating thoughts from your native language. It’s not a proofreading tool in the strictest sense but is ideal for improving sentence readability.
- Best for: Paraphrasing and sentence restructuring
- Caution: Double-check reworded content to ensure meaning hasn’t changed and check for plagiarism
Hemingway Editor
Visit: https://www.hemingwayapp.com
Hemingway highlights overly long or complex sentences, passive voice, and adverbs. It encourages concise, clear writing—something every thesis benefits from.
- Best for: Improving readability and flow
- Caution: Not designed for academic tone or grammar checks
Microsoft Editor / Google Docs Grammar Checker
These built-in grammar tools have become much more advanced and are often the first line of defence for ESL writers. They correct spelling, verb agreement, and basic sentence structure.
- Best for: Everyday grammar checks
- Caution: They miss deeper issues and can’t help with academic style or clarity
Vappingo Thesis Proofreading Services

Editors not only fix errors but also improve structure, tone, and clarity—making your thesis more professional and easier to read. It’s ideal for final drafts and high-stakes documents like dissertations.

How to Use These Tools Effectively
While proofreading tools can be incredibly helpful, using them effectively requires more than simply clicking “accept.” For ESL students, these tools should be part of a broader writing strategy—one that supports learning, not just correction.
Here’s how to get the most out of each tool:
Use tools in stages
Start with grammar and spelling (e.g., Grammarly or Microsoft Editor), then move on to sentence structure and clarity (Hemingway or QuillBot). This layered approach prevents you from getting overwhelmed and helps you focus on one improvement at a time.
Don’t accept every suggestion automatically
Proofreading tools sometimes misunderstand your meaning—especially in academic writing. Before accepting a change, ask yourself:
- “Does this keep the same meaning?”
- “Is this appropriate for formal academic writing?”
Use suggestions as a learning opportunity rather than a shortcut.
Learn from your patterns
Most tools (especially Grammarly) show recurring errors. Keep a log of your most common mistakes so you can look out for them in future drafts. You’ll learn faster—and write more confidently.
Use tools to edit, not write
Write your content freely before running it through a tool. Editing as you go can interrupt your thought process. Draft first, polish later.
Combine tools with human proofreading
No tool is a substitute for a professional editor, especially for academic texts. After using automated tools, submit your thesis to an expert (like Vappingo) to ensure your arguments, tone, and structure meet academic expectations.

When You Still Need a Human Editor
Proofreading tools are powerful, but they aren’t magic. Even the most advanced grammar checkers can’t fully understand the meaning, context, or academic tone behind your words. That’s where human editors—especially those experienced in working with ESL students—come in.
There are several key reasons to invest in professional proofreading for your thesis:
- Automated tools can’t improve academic tone and argument structure: Grammarly might fix a comma or suggest a simpler phrase, but it won’t tell you if your conclusion is weak or your argument lacks flow. Human editors understand what makes a thesis persuasive and coherent.
- Style and formatting require personal judgment: A good editor can adjust your tone to suit your discipline, university guidelines, and audience. They’ll also ensure that headings, references, and language stay consistent—something machines still struggle with.
- ESL writers benefit from personalised feedback: When English isn’t your first language, a professional editor can point out not just what to fix—but why. This helps you learn and improve, making future assignments easier to write.
- Complex or high-stakes documents demand precision: If you’re submitting a master’s thesis, PhD dissertation, or journal article, you can’t afford embarrassing errors. A human proofreader can polish your final draft to perfection.
At Vappingo, we specialise in professional proofreading for ESL thesis writers. Our real human editors will correct your grammar, improve your writing flow, and make sure your academic ideas shine—without changing your meaning or voice. We offer 24/7 online access, fast turnaround, and expert support tailored to your needs.
