Why Brazilian researchers need English manuscript validation
Brazil produces over 58,000 scientific papers annually (13th globally) and ranks 24th in citation impact. The CAPES Qualis system classifies journals from A1 (highest) to C, and high-ranking Qualis journals are almost all English-language international outlets. Faculty evaluation, postgraduate program "concept" scores, and FAPESP/CNPq grant eligibility depend heavily on Qualis-rated publications. Brazilian researchers must write in English to access A1/A2 Qualis rankings, but Portuguese-influenced English patterns — false cognates, preposition differences, double negatives, and longer sentence structures — create barriers to acceptance. CheckMyManuscript validates manuscripts before submission to international journals.
How CheckMyManuscript helps Brazilian researchers
Portuguese English pattern detection
Detect language patterns influenced by Portuguese — including false cognates, preposition errors, gerund/infinitive confusion, and complex sentence structures common in Brazilian academic English.
International journal formatting validation
Validate manuscript structure against requirements of major international journals (Elsevier, Springer, Wiley, Taylor & Francis) and SciELO-indexed journals.
Citation-reference cross-validation
Catch mismatched in-text citations, incomplete bibliography entries, and missing DOIs that trigger desk rejection.
Structured abstract completeness
Verify your abstract contains all required elements (Background, Methods, Results, Conclusion) for your target journal.
Ethics & declarations verification
Flag missing funding statements, conflict of interest declarations, data availability statements, and author contribution sections.
Affordable one-time pricing
Full manuscript check for $5 one-time (approx. R$29) — no monthly subscription. Accessible for Brazilian researchers and graduate students.

The practical edge your peers already use
Across disciplines and career stages, researchers reduce bottlenecks and submit with confidence: clearer drafts, easier guideline compliance, and less back and forth with co‑authors and reviewers.
I use it to review my students' papers. It instantly highlights typos, missing references, and unclear sections, helping me focus my feedback on the quality of the research instead of surface errors.
Ilyass
Professor in Mechanical Engineering, ÉTS Montréal
I relied on it throughout my thesis to strengthen my writing. It suggested clearer phrasing, improved flow between sections, and ensured my references were complete before the final deadline.
Manon
Master's Student in Speech Therapy
I write research in both Portuguese and English, and it adapts perfectly to either language. It provided precise feedback in Portuguese, helping me maintain academic tone and consistency across my drafts.
Afonso
PhD Candidate, UFPE
It gave excellent advice on how to rephrase and present ideas more clearly and concisely. The suggestions helped me refine my arguments and make my research more impactful.
Félix
Postdoc Researcher, Max Planck Institute for Evolutionary Biology
A round of suggestions helped to generally refine the text of my paper and, moreover, to present some of its key points in a more focused form.

Our checker identifies language patterns commonly influenced by Portuguese in academic writing. These include false cognates (words that look similar but have different meanings), preposition errors, gerund/infinitive confusion, and overly complex sentence structures. These patterns are among the most common non-scientific reasons for desk rejection of Brazilian manuscripts at international journals.
Yes. CheckMyManuscript validates against formatting requirements common across major international publishers that make up A1/A2 Qualis journals — including Elsevier, Springer, Wiley, and Taylor & Francis. The checker covers standard formatting, citation, and declaration requirements needed for acceptance at these high-impact outlets.
Absolutely. The free overview check helps you assess submission readiness at no cost, and the full report at $5 (~R$29) is designed to be affordable for students. It's useful for meeting CAPES publication requirements and improving manuscripts before submission to international journals.
