How Journal Policies Distinguish AI Proofreading, Rewriting, and Scientific Drafting
Why do journals distinguish grammar correction from content generation?
Grammar correction ordinarily improves the linguistic presentation of information already established by the researcher. It may address punctuation, sentence agreement, spelling, or grammatical constructions without changing the underlying scientific argument.
Scientific content generation involves producing or substantively modifying information that contributes to the manuscript's claims, explanations, interpretations, or methodological descriptions.
These activities present different editorial concerns. Routine proofreading generally involves limited changes to scholarly substance, whereas content generation may introduce unsupported assertions, inaccurate citations, or interpretations that exceed the evidence.
However, the distinction is not absolute. Grammar editing can change scientific meaning, and extensive linguistic rewriting can sometimes preserve the original research completely.
Journal policies may therefore consider both the purpose of AI assistance and the nature of the resulting changes.
What kinds of AI assistance might journals classify differently?
| AI activity |
Typical contribution |
Publication-policy consideration |
| Spelling correction |
Corrects typographical errors |
May fall within routine proofreading exemptions |
| Grammar and punctuation checks |
Improves linguistic correctness |
May be exempt under policies allowing basic language correction |
| Sentence-level rewriting |
Reformulates existing prose |
May be treated differently depending on the extent and nature of changes |
| Paragraph restructuring |
Changes organization and presentation |
May constitute reportable manuscript-preparation assistance |
| Literature synthesis |
Generates or reformulates scholarly interpretations |
Requires verification and may trigger disclosure requirements |
| Scientific discussion drafting |
Produces explanatory or interpretive content |
May be subject to substantive AI-use rules |
| Data analysis |
Contributes to research procedures or analytical outputs |
May require methodological reporting beyond writing disclosure |
These categories are useful for evaluating assistance, but they should not be mistaken for a classification formally adopted by every publisher.
The distinction between AI grammar correction and scientific content generation depends on the actual output, not simply the prompt used.
What does Elsevier's generative AI policy say?
Elsevier's updated generative AI policies for journals distinguish basic language checks from more substantive AI-assisted manuscript preparation.
Basic spelling, grammar, and punctuation checks are treated differently from substantive changes to sentence structure, organization, or content. The latter may require a declaration even when the researcher describes the activity as language editing.
Elsevier also emphasizes that authors remain responsible for the accuracy and integrity of their submitted work, including AI-assisted material.
The practical implication is that a researcher should examine what the tool changed. A correction of subject-verb agreement is different from an AI-generated explanation of an unexpected finding.
Researchers should verify the current policy and any journal-specific instructions rather than assume that every activity labeled editing receives the same treatment.
How does Springer Nature approach AI-assisted writing?
Springer Nature provides guidance on generative AI use in manuscript preparation and distinguishes language assistance from more substantive forms of AI-generated content.
Its guidance emphasizes the responsibilities of human authors and the need for scientific arguments, interpretations, and conclusions to remain appropriately controlled and verified.
Researchers should consult the applicable publisher and journal requirements to determine whether a particular editing activity needs acknowledgment or declaration.
Permission to use AI for language improvement should not be interpreted as permission to include unsupported scientific claims or invented references.
What does ICMJE recommend?
The International Committee of Medical Journal Editors provides recommendations addressing AI-assisted technologies in scholarly publishing.
Its guidance emphasizes transparency about relevant AI use, verification of generated content, and continued responsibility of human authors.
ICMJE also distinguishes AI used to assist manuscript writing from AI used as part of the research methodology. The latter may require description in the Methods section because it affects how the study was conducted.
These recommendations influence scholarly publishing practices, but individual journals may implement them through different submission requirements.
Researchers should not assume that ICMJE guidance automatically establishes the precise disclosure procedure for every journal.
What role does COPE play?
The Committee on Publication Ethics provides guidance concerning AI tools, authorship, and publication integrity.
COPE maintains that AI tools cannot qualify as authors because they cannot assume the responsibilities associated with human authorship.
This principle applies regardless of whether AI was used for grammar correction or substantive drafting.
COPE guidance should be distinguished from the operational submission requirements established by individual publishers and journals.
A researcher should therefore consult both relevant publication-ethics guidance and the specific rules governing the intended manuscript submission.
How do publisher approaches compare?
Different organizations address overlapping concerns but do not necessarily use identical definitions or disclosure procedures.

This comparison summarizes broad policy emphases rather than every clause of the organizations' current guidance. Policies can change, and individual journals may impose additional requirements.
Does the same AI tool fall under different policy categories?
Yes. The identity of the tool does not determine the nature of its contribution.
ChatGPT, for example, may correct a grammatical error in one interaction and generate a substantial scientific interpretation in another.
The first activity may fall within a journal's routine language-editing category. The second may require disclosure and independent verification as substantive manuscript preparation.
Researchers should avoid classifying all uses of a particular AI system as either automatically acceptable or automatically prohibited.
What matters is how the system was used, what it produced, and which publication rules apply.
Can a grammar correction become substantive scientific editing?
Yes. An apparently minor revision may change scientific certainty, causality, or technical meaning.
Consider the original sentence: "Greater platform participation was associated with higher student engagement."
If AI rewrites it as "Greater platform participation significantly improved student engagement," the revision introduces statistical significance and a causal interpretation.
The change is no longer merely grammatical, regardless of whether the researcher originally requested proofreading.
Such changes should be checked against the research evidence and evaluated under the journal's relevant policy category.
This illustrates why AI-assisted editing can strengthen scientific claims without the researcher's intention.
Does extensive rewriting always count as content generation?
Not necessarily. Extensive rewriting may change sentence structure and improve readability while preserving the original scientific meaning.
For example, a multilingual researcher may use AI to improve the English expression of an entire manuscript without introducing new interpretations or results.
Nevertheless, a publisher may classify substantial rewriting differently from routine proofreading for disclosure purposes.
Scientific equivalence and policy classification are separate questions. A revision can preserve the science and still require disclosure because of the nature or extent of the assistance.
The relationship between editing extent and disclosure requirements should therefore be evaluated using the target journal's actual instructions.
What if AI-generated content is completely rewritten by the researcher?
Manual rewriting does not necessarily eliminate a disclosure obligation.
Some policies concern the use of AI during manuscript preparation, not only the amount of generated wording retained in the final submission.
If the researcher retains an AI-proposed interpretation or argument structure, the assistance may remain substantive even after extensive manual revision.
Conversely, rejected suggestions may be treated differently under policies focused on contributions incorporated into the manuscript.
Researchers should describe their actual use of AI rather than assume that paraphrasing generated content changes its original contribution.
Do journals use AI-detection scores to determine disclosure?
AI-text detection scores do not establish how a manuscript was prepared or whether the assistance meets a journal's disclosure criteria.
A detector may incorrectly classify independently written text or fail to identify AI-assisted material. It also cannot reliably distinguish routine grammar correction from substantive scientific generation merely by examining the final prose.
Researchers should therefore base declarations on their actual activities and the applicable policy.
A low AI-detection score does not remove an existing disclosure obligation, and a high score does not independently prove that the author violated a publication rule.
What if a journal has no explicit AI grammar policy?
The absence of a specific grammar-editing provision does not necessarily establish that every form of AI assistance is unrestricted.
Researchers should review the journal's broader author instructions, publisher policies, and submission declarations.
If the activity involved substantive rewriting or generated scientific content and the rules remain unclear, seeking clarification from the editorial office may be appropriate.
Researchers should also preserve sufficient records to explain the assistance accurately if questions arise during editorial review.
Does disclosure resolve concerns about AI-generated content?
No. Disclosure communicates the role of AI assistance but does not establish the accuracy or acceptability of the resulting material.
Authors must verify AI-generated scientific claims, methodological descriptions, numerical statements, and citations.
A disclosed fabricated reference remains fabricated. A declared but unsupported causal interpretation remains scientifically problematic.
The principles for verifying AI-rewritten scientific text apply regardless of the disclosure category.
Watch Out
Do not assume that every journal follows the same AI policy. A publisher may distinguish basic proofreading from substantive rewriting, while another publication may impose broader disclosure requirements. Check the actual policy before submission.
