Plagiarism Check

About This Service

Our Plagiarism Check service provides a comprehensive similarity analysis of your academic document using industry-leading detection software that cross-references your text against billions of published sources, academic databases, institutional repositories, and internet content. The result is a detailed similarity report with a percentage score and highlighted passages, giving you full visibility into any areas that may require revision before submission.

Academic integrity is a cornerstone of scholarly publishing. Most journals, universities, and funding bodies require authors to confirm that their work is original and properly attributed. Our Plagiarism Check service helps you identify unintentional similarity, improperly paraphrased sources, missing citations, and self-plagiarism from your own previously published work — all before your manuscript reaches a reviewer.

The similarity report includes a colour-coded breakdown of matched passages, the sources matched against each highlighted section, and an overall similarity percentage. Where passages are flagged, we provide brief guidance on whether the similarity represents a citation issue, a common phrase, or a section that may benefit from paraphrasing.

This service is suitable for all types of academic documents: journal articles, dissertations, theses, research proposals, conference papers, book chapters, and student assignments. It is particularly recommended as a final step before journal submission or institutional assessment.

The Plagiarism Check can be ordered as a standalone service or combined with our proofreading or editing services. Many researchers choose to run a plagiarism check after editing is complete, ensuring that the final, polished version of their document is both linguistically accurate and fully original.

All documents submitted for plagiarism checking are handled with complete confidentiality. Reports are delivered directly to you and are not retained or shared with any third party.

Frequently Asked Questions

Everything you need to know about our Plagiarism Check service.

Our detection software cross-references your text against billions of published sources, including academic journals, conference proceedings, institutional repositories, theses and dissertations, internet content, and previously submitted documents. The result is a comprehensive similarity report covering both published and unpublished sources.

Acceptable similarity thresholds vary by journal and institution. Most peer-reviewed journals consider a similarity score below 15–20% acceptable, provided that matched passages are properly cited and the overall originality of the work is clear. We provide guidance on interpreting your report alongside the score.

Detection software flags all matching text, including quoted passages that are correctly cited. These matches are highlighted in the report but are not considered problematic as long as they are properly attributed. Our report guidance helps you distinguish between acceptable matches and areas that genuinely need attention.

Yes. The similarity report can be submitted as evidence of originality to journals, universities, or funding bodies that require it. Many institutions now routinely request plagiarism reports as part of the submission or examination process.

Yes. We can check journal articles, dissertations, theses, research proposals, conference papers, book chapters, and student assignments. The service is available for documents in English, Turkish, or bilingual format.

At Lexic Editing, we provide comprehensive academic editing services for researchers, scholars, and graduate students. Our team works on a wide range of academic documents, including journal articles, dissertations, theses, research proposals, conference papers, and book chapters across all disciplines. Whether you’re preparing a manuscript for publication or refining a major research project, we ensure your writing is clear, polished, and ready for submission. Our editors are experienced in various academic styles and fields, helping you meet the formatting, language, and structural standards required by journals and institutions worldwide.

Once you submit your document and complete payment, your order is assigned to an editor with expertise in your subject area. The process unfolds in several stages:

1. Initial Review — Your editor reads through the entire document to understand your argument, identify recurring issues, and note any discipline-specific conventions to follow.

2. Language & Style Editing — Grammar, spelling, punctuation, sentence structure, and word choice are refined for clarity and precision. Awkward phrasing is rewritten, overly complex sentences are simplified, and vocabulary is elevated where appropriate — all while preserving your academic voice.

3. Flow & Coherence — Transitions between sentences and paragraphs are improved so your argument reads logically and cohesively from start to finish.

4. Formatting & Consistency — Headings, citations, reference style (APA, MLA, Chicago, etc.), capitalization, and number formatting are reviewed for consistency throughout.

5. Final Proofread — A final pass catches any remaining typos or errors before delivery.

You receive your document with tracked changes enabled (in Word format), so you can accept, reject, or review every edit. An editor's summary note is also included, briefly explaining the main changes made and any areas that may need your attention.

Turnaround depends on the service level selected. Standard is 5–7 business days, Express is 48 hours, and Rush is 24 hours. Exact deadlines are shown before checkout.

Yes. Every completed order includes a digitally verifiable Certificate of Professional Editing that you can submit alongside your manuscript.

We accept .docx, .doc, .pdf, .tex, and .txt files. For the best editing experience we recommend .docx so tracked changes can be returned.
