Common Mistakes Researchers Make When Using AI for Paper Writing
Over the last two years, I have seen researchers including very bright PhD students make the same avoidable mistakes when using AI writing tools. Here are the most important ones to watch out for:
- Mistake 1 – Submitting unverified AI output: AI can generate confident-sounding but factually incorrect statements. Always verify every claim, statistic, and citation that an AI tool produces.
- Mistake 2 – Over-relying on ChatGPT for original ideas: AI is a productivity tool, not a source of original research. Your intellectual contribution must always come from you.
- Mistake 3 – Not disclosing AI use: Many journals now require you to declare AI tool usage. Failing to do so can result in rejection or retraction.
- Mistake 4 – Ignoring plagiarism checks: AI-generated text can sometimes reproduce phrases from training data. Always run your paper through a plagiarism checker like iThenticate before submission.
- Mistake 5 – Using AI only at the end: The best researchers integrate AI at every stage — from literature review to final proofreading — not just as a last-minute grammar checker.
- Mistake 6 – Using wrong AI tools for the task: Not all AI tools are equal. Use Elicit for literature, ChatGPT for drafting, Trinka for scientific language correction, and Scite for citation verification.
Expert Tips from Dr. Somasundaram R
After 10 years of research in IoT, Cybersecurity, and AI, and guiding dozens of PhD scholars through publication, here is what I have learned about using AI tools for research paper writing effectively:
- Tip 1 – The PQSR Prompt Formula: For ChatGPT, always structure your prompts as: Purpose + Quality + Subject + Requirements. Example: ‘Write a high-quality introduction for a research paper on machine learning-based intrusion detection, for an IEEE journal, in about 350 words, with a formal academic tone.’
- Tip 2 – Layer your AI tools: Use Elicit for literature search → SciSpace for understanding → ChatGPT for writing → Grammarly + Trinka for editing → Scite for citation verification. Each tool does one job excellently.
- Tip 3 – Never paste AI output directly: Always read, understand, and rewrite AI-generated content in your own academic voice. Add your domain expertise and original insights.
- Tip 4 – Use AI for reviewer responses: When you get reviewer comments back, use ChatGPT to help you draft polite, structured, and thorough responses. This is one of the most underused applications of AI in academia.
- Tip 5 – Start with the abstract: If you are stuck, ask ChatGPT to write an abstract from your key findings. A well-structured abstract often unlocks the writing for the entire paper.
- Tip 6 – Maintain your research integrity: AI is your co-pilot, not your author. The ideas, experiments, data, analysis, and conclusions must always be genuinely yours.
Future Trends: AI in Research Paper Writing
The landscape of AI-assisted academic writing is evolving rapidly. Here is what researchers should prepare for in the coming years:

AI tools can help you draft, edit, and structure your paper, but the intellectual content your research question, experimental design, data collection, analysis, and conclusions must always be genuinely yours. Using AI to fabricate research or submit AI-generated text as your own work is a serious academic integrity violation. AI is a powerful productivity tool, not an authorship substitute.
Q3. Which free AI tools are best for PhD research paper writing?
For researchers on a budget, the best free AI tools are: Research Rabbit (100% free), Elicit (free plan available), SciSpace (free plan available), ChatGPT Free (GPT-3.5 and limited GPT-4o), and Grammarly Free (basic grammar checks). For citation verification, Scite Assistant offers a 7-day free trial.
Q4. Is it ethical to use AI tools for research paper writing?
Yes, as long as you follow three key principles: (1) Disclose your AI use clearly in the paper — most journals now require this. (2) Never present AI-generated ideas as your own original research contribution. (3) Always verify AI-generated content, especially facts, statistics, and citations, against peer-reviewed sources. Ethical AI use is about transparency, verification, and genuine intellectual contribution.
Q5. How does ChatGPT help in writing a research paper?
ChatGPT helps researchers by: generating structured outlines for papers, drafting sections like the introduction and conclusion, simplifying complex technical explanations, suggesting synonyms and paraphrases for clearer writing, helping respond to peer reviewer comments, and summarising long research articles into key points.
