Manuscript Submission: 5 Critical Checks for Researchers

16

Most researchers treat peer review as the first real test of their manuscript. It isn’t. Before a single reviewer reads your work, your manuscript passes through a series of filters: editorial screening, similarity checks, compliance review, reference verification. Any one of these can return a manuscript to your inbox, sometimes with no feedback beyond “does not meet submission requirements.”

The frustrating part is none of these are judgments on your research. They’re judgments on your preparation. A manuscript submission checklist addresses this gap, bridging the distance between research that’s complete and a manuscript that’s ready to submit. Here are the five checks that matter most, and what happens when you skip them.

Check #1: Language, Grammar, and Clarity

Strong research can still lose reviewer confidence if the writing is unclear. Reviewers aren’t just evaluating your methodology, they’re reading your manuscript, and issues in the reading experience translate to friction in the evaluation.

Common language issues that affect reviewer perception:

• Grammar errors and inconsistent tense. Particularly in methods and results sections, where precision is expected
• Awkward phrasing. Sentences that are technically correct but difficult to follow
• Terminology inconsistency. Referring to the same concept with different terms across sections (e.g., “participants” in one section, “subjects” in another)
• Wordiness. Overlong sentences that bury the key finding
• Unclear transitions. Paragraphs that don’t connect logically

For non-native English speakers, this challenge is compounded. A 2023 PLoS Biology article revealed that non-native English-speaking researchers spend a disproportionate amount of time on writing, language editing, and manuscript preparation—time that could otherwise be spent on research. The study also found that they face 2.6 times higher rates of manuscript rejection due to language-related issues compared to native English-speaking researchers.

Before you submit: Choose a dedicated academic language check, not just a standard spelling and grammar checker. General writing tools often flag passive voice or formal constructions that are perfectly acceptable in scholarly writing, while overlooking issues such as awkward phrasing, terminology inconsistencies, and discipline-specific language nuances. Academic writing assistants like Paperpal are designed to recognize scholarly conventions and provide feedback tailored to academic manuscripts.

Check #2: Plagiarism and Similarity Screening

Most researchers understand that copying others’ work is unacceptable — but plagiarism risks in academic writing are broader than intentional copying. Unintentional similarity, self-plagiarism, and increasingly, AI-generated plagiarism (where AI tools reproduce phrasing from existing sources without attribution) are just as likely to trigger a similarity flag.

Journals run manuscripts through similarity detection software (Turnitin, iThenticate) before or during peer review. A high similarity score doesn’t automatically mean misconduct, but it does trigger scrutiny — and any unexplained overlap, regardless of source, can delay or derail a submission.

Key distinctions every researcher should know

Type	Acceptable?	Notes
Citing and quoting another author’s work	Yes, with citation	Needs quotation marks and reference
Paraphrasing your prior methods section	Depends on journal	Some journals allow it with disclosure
Reproducing paragraphs without attribution	No	Even from your own prior work
AI-generated text matching existing sources	No	AI tools can reproduce published phrasing without flagging it
Standard phrases (“p < 0.05”)	Yes	Formulaic language is excluded by most tools

Before you submit: Be sure to use a trusted plagiarism check for research papers before submission, not after you receive an editor query. This is especially important if AI was used at any stage of writing, since AI-generated text can inadvertently mirror published content in ways that aren’t obvious to the author. Catching overlaps early gives you time to rephrase, attribute correctly, or add a disclosure where needed.

Do this now: Upload your manuscript to run Paperpal’s similarity check to catch overlaps in your work, including unintentional self-plagiarism, while you still have time to address them.

Check #3: AI Writing Detection and Disclosure

The use of AI writing tools in academic publishing has grown faster than most researchers realize, or disclose. A 2025 study in Science points to growing AI use, with AI-generated text seen in nearly 15% of methods sections and 7% of peer reviewer reports in the final quarter of 2024 alone. The study also states that “four times as many authors use AI as admit to it”.

Journal policies have responded accordingly. Most major publishers prohibit listing AI tools as authors and require disclosure of any AI use in manuscript preparation. Policy compliance, however, is only one concern for researchers; the other is AI accuracy.

Risks of unreviewed AI-generated content

• Hallucinated citations. AI tools can generate plausible-looking but entirely fabricated references, a problem documented in multiple published retractions
• Inaccurate summaries. AI paraphrasing of prior literature can subtly misrepresent findings
• Loss of author voice. Sections written or heavily edited by AI may read inconsistently with the rest of the manuscript
• Factual errors. AI tools can conflate studies, merge findings from different papers, or introduce incorrect statistics

Before you submit: Add AI detection for academic writing to your manuscript submission checklist, both to flag sections that need closer review, and to ensure your AI disclosure statement accurately reflects how AI was used. If you’re wondering how to frame these AI use statements, Paperpal provides publisher-aligned AI disclosure templates, so you don’t need to hunt through individual journal guidelines to get the language right.

Do this now: Let Paperpal scan for AI writing across your research manuscript, review the sentence-level insights, and refine as needed to stay compliant and protect your authorship.

Check #4: Reference Accuracy and Citation Quality

Citation errors are one of the easiest ways to frustrate a reviewer and undermine the credibility of an otherwise strong manuscript. They’re also remarkably common. According to a ScienceDirect analysis, reference error rates across disciplines range from 25% to 54%, spanning minor inaccuracies to major misrepresentations that alter the meaning of a cited work. The increasing use of AI in academia is adding another layer of risk, with hallucinated or inaccurate citations contributing to a growing retractions crisis: the Retraction Watch Database now holds just shy of 55,000 entries, with 2023 setting a record of over 14,000 retraction notices issued in a single year.

Common problems with references and citations

• Hallucinated or fabricated references. AI-generated sources that look plausible but are made up, incomplete, or unreliable
• Broken citation-reference links. In-text citation numbers that don’t correspond to any entry in the reference list (or vice versa)
• Author name errors. Misspelled names, wrong initials, or incorrect author order
• Missing volume or page information. Particularly common when citing recently published or preprint articles
• Formatting inconsistencies. Mixing two citation styles, or inconsistently applying a single style
• Outdated or retracted references. Citing a finding that has since been superseded, corrected, or retracted

Before you submit: Put your essay, thesis, or research manuscript through a trusted reference checker to catch broken links, formatting inconsistencies, and references that may have been retracted since you cited them. A manuscript review before submission that skips this step is incomplete.

Do this now: Turn to Paperpal for a detailed reference check, which includes 9 key reviews to spot critical citation errors and/or missing details in your work before an editor does.

Check #5: Journal Compliance and Submission Readiness

This is the check researchers most often skip, and the one editors see ignored most often. A recent ecrLife article revealed that 30% to 70% of manuscripts submitted to major academic journals are desk rejected, and a significant share of these are due to avoidable compliance issues rather than the quality of the science.

The most common issues with journal submissions

• Word count violations. Exceeding limits for abstract, main text, or supplementary materials
• Reference list length. Some journals cap references; ignoring this is a common oversight
• Figure and table requirements. Resolution, file format, and labeling conventions
• Structured abstract format. Required headings vary by journal; there’s no universal structure for the background/objective/methods/results/conclusions
• Ethics declarations. Conflict of interest statements, informed consent, institutional approvals, animal welfare statements, funding acknowledgements, and more
• Supplementary files. Some journals impose specific formats or size limits

As one journal editor put it: “It never ceased to amaze me how easily authors let their research perish just because they did not read the instructions for authors.” A desk rejection for a compliance issue means weeks of delay, resubmitting to the same journal, or starting over with a new target. Either way, the research waits.

Before you submit: Read through your target journal’s author guidelines section by section—not as a formality, but as a direct comparison against your manuscript. Most compliance issues aren’t discovered; they’re simply never checked for.

Do this now: Use Paperpal’s journal submission checks to verify your manuscript before you submit. With 30+ checks across the key parameters editors and reviewers look for, it’s your last line of defence to ensure your work is complete and meets the stringent requirements of academic publishing.
