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.

Frequently asked questions

Yes. The full 80+ check detailed report costs $5 one-time (approximately R$29). There is no monthly subscription required. A free overview check is also available for every manuscript — upload your paper and get an instant readiness score with key issues highlighted.

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.
