PLOS Medicine at a glance
Key metrics to place the journal before deciding whether it fits your manuscript and career goals.
What makes this journal worth targeting
- IF 12.4 puts PLOS Medicine in a visible tier — citations from papers here carry real weight.
- Scope specificity matters more than impact factor for most manuscript decisions.
- Acceptance rate of ~~15% means fit determines most outcomes.
When to look elsewhere
- When your paper sits at the edge of the journal's stated scope — borderline fit rarely improves after submission.
- If timeline matters: PLOS Medicine takes ~6-8 weeks. A faster-turnaround journal may suit a grant or job deadline better.
- If OA is required: gold OA costs $5,900 USD. Check institutional agreements before submitting.
Quick answer: The PLOS Medicine AI policy follows PLOS's rules calibrated to medical research with global-health-relevance and methodological transparency submissions. AI tools can be used for manuscript preparation but every use must be disclosed in the Methods section, with PLOS Medicine's editorial team checking specifics at desk-screen. AI cannot be listed as an author of any PLOS Medicine paper. AI-generated figures and schematics representing original research data are prohibited under PLOS Medicine's image-integrity standard. PLOS Medicine editors treat undisclosed use as a publication-ethics violation per ICMJE + COPE.

We do not train AI on your manuscript and delete it within 24 hours.
Editorial detail (for desk-screen calibration). Editor-in-Chief: Linda Williams (PLOS) leads PLOS Medicine editorial decisions. Editorial-board listings change; verify the current incumbent at the journal's editorial-team page before quoting the name in a submission cover letter. Submission portal: https://journals.plos.org/plosmedicine. Manuscript constraints: 300-word abstract limit and no strict main-text cap (PLOS Medicine enforces methodological completeness over length). We reviewed PLOS's AI policy framework against current PLOS Medicine author guidelines (accessed 2026-05-08); evidence basis includes both publicly documented PLOS policy and our internal anonymized submission corpus. The applicable word limit at PLOS Medicine is shown below: 300-word abstract limit and no strict main-text cap (PLOS Medicine enforces methodological completeness over length).
The manuscript word limit at this journal is 300 words for main text (verify article-type-specific caps in the latest author guidelines). The named editorial-culture quirk: PLOS Medicine academic editors enforce reproducibility-first review with explicit data-availability and code-availability statements.
What does PLOS Medicine's AI policy require?
PLOS Medicine authors must follow four rules under PLOS's AI framework, all enforced at desk-screen:
Rule 1: Disclose every AI tool used in manuscript preparation
Authors must name every generative AI tool used, its version, and how it was used. The disclosure goes in the Methods section, not the Acknowledgments. Examples that REQUIRE disclosure at PLOS Medicine:
- For PLOS Medicine-targeted manuscripts addressing medical research with global-health-relevance and methodological transparency: using ChatGPT, Claude, Gemini, or similar to draft, polish, or edit manuscript text passing through PLOS Medicine editorial review
- For PLOS Medicine submissions: using AI to generate boilerplate text for limitations, ethics statements, or PLOS Medicine-specific response-to-reviewers letters that cite PLOS's framework
- For PLOS Medicine submissions: using AI to translate manuscript text into English from another language, with PLOS expecting disclosure of the source language and translation chain
- For PLOS Medicine literature reviews: using AI for citation discovery or summarizing prior PLOS Medicine work; PLOS's policy applies regardless of citation context
- For PLOS Medicine analytical pipelines: AI-assisted code generation requires Methods + code disclosure under ICMJE + COPE, particularly when code touches medical research with global-health-relevance and methodological transparency analysis
Examples that do NOT require AI disclosure:
- At PLOS Medicine, using grammar/spell checkers (Word, Grammarly basic) that do not generate new content for the manuscript
- For PLOS Medicine submissions, using reference managers (Zotero, EndNote) for citation formatting against PLOS's style guide
- For PLOS Medicine statistical analysis, using established statistical software (R, Stata, SPSS) where the algorithm is the established tool documented in PLOS Medicine's methodological norm, not a generative AI
Rule 2: AI cannot be an author
No AI tool can be listed as an author of a PLOS Medicine paper, particularly for medical research with global-health-relevance and methodological transparency-class submissions. Under PLOS's policy: authorship requires the ability to take responsibility for the content, agree to be accountable for accuracy, and to consent to publication. AI tools cannot do any of these in PLOS Medicine's editorial framework. This rule is consistent across all PLOS-published journals and applied at PLOS Medicine's desk-screen.
Rule 3: AI-generated figures are prohibited for original research data
PLOS Medicine editorial team does not accept AI-generated images, figures, or schematics that represent original research data in medical research with global-health-relevance and methodological transparency-class submissions. AI tools may assist with figure layout (axis labeling, color schemes) but the underlying data visualization must come from the actual research. AI-generated diagrams used for conceptual illustrations (e.g., a schematic of a hypothesized mechanism) require explicit disclosure and a statement that the diagram is conceptual.
Rule 4: Disclose AI use in peer review participation
Reviewers writing reports for PLOS Medicine cannot use generative AI to draft their reports without disclosing it to the editor. Some PLOS journals prohibit AI-assisted reviewing entirely; PLOS Medicine follows PLOS's default of disclosure-required. The editor decides whether the report is acceptable based on disclosure.
How does PLOS Medicine's AI policy compare to peer journals?
Rule | PLOS Medicine stance | PLOS default | ICMJE/COPE alignment |
|---|---|---|---|
AI authorship | Prohibited | Prohibited | ICMJE-aligned |
Disclosure location | Methods section | Methods section | ICMJE-aligned |
AI-generated figures | Prohibited for original data | Prohibited | COPE image-integrity-aligned |
Reviewer AI use | Disclosure required | Disclosure required | COPE peer-review-aligned |
Enforcement intensity | Desk-screen check | Desk-screen check | Pre-publication enforcement |

What does AI disclosure look like in a PLOS Medicine Methods section?
Acceptable disclosure language for PLOS Medicine submissions:
"For our medical research with global-health-relevance and methodological transparency-focused manuscript at PLOS Medicine, we used ChatGPT-4o (OpenAI, version dated October 2024) to polish English-language phrasing in the Introduction and Discussion sections. We did not use generative AI for data analysis, figure generation, or substantive manuscript content. All authors reviewed and edited the AI-assisted text and take responsibility for the final manuscript."
Or, for AI-assisted code:
"For this PLOS Medicine submission addressing medical research with global-health-relevance and methodological transparency, initial Python code for the Bayesian regression analysis was drafted with Claude 3.5 Sonnet (Anthropic, version dated December 2024). All code was reviewed, modified, and validated by the authors before use; the final version is available at [repository URL]. Statistical inference was performed using the established R package brms."
What does NOT pass PLOS Medicine's desk-screen:
- For PLOS Medicine addressing medical research with global-health-relevance and methodological transparency: "AI tools were used in manuscript preparation." Too vague for PLOS editorial review of PLOS Medicine submissions; the PLOS Medicine editorial team needs the specific tool name, version, and specific use case
- "We acknowledge AI assistance in the Acknowledgments." (Wrong location; must be Methods)
- "ChatGPT helped write this paper." (Insufficient detail on use case)
- No disclosure when AI was used (publication-ethics violation)
What do pre-submission reviews reveal about PLOS Medicine's AI-disclosure desk-screen failures?
In our pre-submission review work on PLOS Medicine-targeted manuscripts, three patterns most consistently predict AI-policy desk-screen flags at PLOS Medicine. Of the manuscripts we screened in 2025 targeting PLOS Medicine and peer venues, the patterns below are the same ones PLOS editorial AI working group flags during editorial review.
AI disclosure missing despite obvious AI-assisted phrasing. PLOS Medicine editors identify AI-drafted text by patterns like overuse of em-dashes, formulaic transitions ("In conclusion," "Furthermore"), and uniform sentence length variance. When the manuscript shows these patterns but contains no AI disclosure, it triggers an editorial query. Check whether your manuscript reads as AI-assisted
AI disclosure in Acknowledgments instead of Methods. PLOS Medicine editorial team flags this as a common mistake against medical research with global-health-relevance and methodological transparency submissions. PLOS's policy specifies Methods placement so that the disclosure is part of the methodological record, not a courtesy under PLOS Medicine's editorial culture. Misplaced disclosures get flagged at desk-screen and require resubmission. Check whether your AI disclosure is in the right section
Generic disclosure language without tool name and version. PLOS Medicine editorial team requires the specific tool, its version (or access date), and the specific use case. "AI tools were used" without specifics gets returned. Check whether your AI disclosure has the required specificity
What is the PLOS Medicine AI-policy compliance timeline?
Stage | Duration | What happens |
|---|---|---|
Author drafts AI disclosure | 30-60 minutes | Identify all AI use, gather tool versions, write Methods paragraph |
Co-author review of disclosure | 1-2 days | All authors confirm the disclosure is complete and accurate |
Editorial desk-screen check | 1-2 weeks | PLOS Medicine's editorial team verifies disclosure against the manuscript |
Editorial query (if disclosure incomplete) | 5-10 days | Editor requests revision before sending to peer review |
Reviewer AI-disclosure check | During peer review | Reviewers verify the disclosure matches the manuscript style |

Submit If
- For PLOS Medicine submissions on medical research with global-health-relevance and methodological transparency: the manuscript explicitly discloses every AI tool used, with name, version, and specific use case in the Methods section, calibrated to PLOS Medicine's editorial expectations
- For PLOS Medicine: no AI tool is listed as an author; all listed authors meet ICMJE authorship criteria, agree to take responsibility, and PLOS expects this acknowledgment in the cover letter
- For PLOS Medicine: figures and schematics representing original research data come from the actual research, not AI generation, with PLOS Medicine editorial team checking image-integrity at desk-screen
- For PLOS Medicine submissions: the disclosure includes a statement that all human authors reviewed and edited the AI-assisted text, with PLOS requiring this acknowledgment per ICMJE + COPE

Think Twice If
- The manuscript shows AI-drafted text patterns (em-dash overuse, formulaic transitions) but contains no AI disclosure; PLOS Medicine desk-screen will flag this.
- The AI disclosure is in the Acknowledgments instead of the Methods section, against PLOS's explicit guidance.
- The disclosure language is generic ("AI tools were used") without specifying tool name, version, and use case; PLOS Medicine editors return manuscripts with this gap.
- Any figure or schematic representing original research data was generated by AI; PLOS Medicine prohibits this regardless of disclosure.
Manusights submission-corpus signal for PLOS Medicine. Of the manuscripts our team screened before submission to PLOS Medicine and peer venues in 2025, the AI-policy compliance gap most consistent across the cohort is generic disclosure language without tool-version specificity. In our analysis of anonymized PLOS Medicine-targeted submissions, manuscripts with complete AI disclosure (tool name, version, specific use case, all-author confirmation) clear desk-screen at the same rate as manuscripts without AI use; manuscripts with incomplete or missing disclosure trigger editorial queries that add 1-2 weeks to the timeline. PLOS editorial AI working group reviews disclosures against ICMJE + COPE framework requirements, and PLOS Medicine applies that framework consistently with PLOS's broader policy. Recent retractions in the PLOS Medicine corpus include 10.1371/journal.pmed.1004087, 10.1371/journal.pmed.1003756, and 10.1371/journal.pmed.1004251. Citing any of these without acknowledging the retraction is an automatic publication-ethics flag, separate from AI-disclosure issues.
What can PLOS Medicine authors do to stay ahead of AI policy changes?
PLOS's AI policy framework continues to evolve as 2026 brings new ICMJE recommendations, COPE guidance refinements, and journal-specific clarifications. PLOS Medicine authors targeting medical research with global-health-relevance and methodological transparency submissions should track three signals throughout 2026:
Quarterly policy updates from PLOS. PLOS editorial AI working group reviews the AI framework on a rolling basis. PLOS Medicine authors who pre-register their disclosure language at submission time tend to face fewer revisions during the 2026 transition period than authors who write boilerplate disclosures.
Field-specific clarifications for medical research with global-health-relevance and methodological transparency. Different research domains see different AI use patterns. PLOS Medicine's editorial team has been refining what counts as "substantive AI use" versus "ancillary AI assistance" for medical research with global-health-relevance and methodological transparency work. Authors who err on the side of more disclosure rather than less avoid the publication-ethics gray zone.
Reviewer disclosure norms. As PLOS extends AI-disclosure rules to peer reviewers, the response rate from PLOS Medicine reviewers may shift. Authors should expect that PLOS Medicine reviewers' use of AI tools is now also disclosed and factored into editorial decisions.

Frequently asked questions
Yes, with mandatory disclosure. PLOS Medicine follows PLOS's AI policy under the ICMJE + COPE framework. AI tools can be used for language editing, manuscript preparation, and analysis support, but all use must be disclosed in the Methods section. AI cannot be listed as an author, and human authors bear full responsibility for the content.
In the Methods section. Authors must name the specific AI tool (e.g., ChatGPT-4o, Claude 3.5 Sonnet), its version, and describe how it was used. The disclosure should confirm that all human authors reviewed and take responsibility for the AI-assisted content. PLOS Medicine's editorial team checks this disclosure during desk-screen.
No. PLOS Medicine prohibits AI-generated figures, schematics, and images intended to represent original research data. AI tools may assist with figure layout and labeling, but the underlying data and visualizations must come from the actual research. This rule is part of PLOS's broader image-integrity policy.
PLOS Medicine treats undisclosed AI use as a publication-ethics violation following COPE guidelines. Consequences range from required correction to expression of concern or retraction, depending on severity. PLOS may notify the authors' institution in serious cases.
The core requirements (disclosure in Methods, no AI authorship, no AI-generated figures) are consistent across PLOS-published journals. PLOS Medicine applies these rules consistently with PLOS's broader policy framework. The journal-specific element is enforcement intensity at desk-screen, which at PLOS Medicine is calibrated by plos medicine academic editors enforce reproducibility-first review with explicit data-availability and code-availability statements.
