How to Improve Your Text Originality
Getting a high uniqueness score is not only about avoiding direct copying. It is about writing in a way that clearly shows your own thinking. Here are practical techniques that consistently help English-speaking students, researchers, and writers raise originality without losing clarity or academic quality.
1. Paraphrase properly — don’t just swap wordsSimply replacing words with synonyms (e.g., “important” → “significant”) rarely fools modern plagiarism checkers and often produces awkward sentences. Instead:
• Read the original passage carefully.
• Put it aside and write the idea in your own words from memory.
• Change the sentence structure (turn active voice into passive, combine or split sentences).
• Keep the original meaning but use different vocabulary and rhythm.
2. Add your own analysis and examples Pure summary of other people’s ideas scores lower than content that includes your interpretation. After presenting a source, add:• Your evaluation (“This approach works well in small teams but may fail in large organizations because”)
• A concrete example from your experience, research, or a current event
• A short comparison with another viewpoint
These additions are almost always unique and significantly increase the originality percentage.
3. Use quotations strategicallyWhen the original wording is particularly strong or you need to cite a definition, use a direct quotation and cite it correctly. Do not over-quote. A good rule of thumb is that quotations should make up no more than 10–15% of an academic paper. Always introduce the quote and explain its relevance afterward.
4. Synthesize multiple sourcesInstead of discussing one source after another, combine ideas from two or three sources in a single paragraph and show how they relate. This creates original connections that no single source contains and is highly valued by both plagiarism detectors and human readers.
5. Rewrite topic sentences and conclusionsMany students copy the opening and closing sentences of paragraphs from sources. Make sure every topic sentence and concluding sentence is written in your own voice. These are the places where originality is most visible.
6. Check and revise in stages• Write your first draft freely.
• Run it through the plagiarism checker.
• Focus only on the highlighted matching sections.
• Rewrite those parts using the techniques above.
• Check again. Most people need two or three rounds to reach a strong uniqueness score.
7. Common mistakes that lower your score• Copying sentence structures even when words are changed
• Using too many short phrases from the original (“according to the study”, “the results show that”)
• Leaving in-text citations without properly paraphrasing the surrounding text
• Submitting text that was previously published by you on another platform (self-plagiarism)
Quick checklist before final submission• Have I explained the ideas in my own words?
• Did I add at least one original insight or example per major section?
• Are all direct quotations properly marked and cited?
• Does the text sound like me when I read it aloud?
Applying these methods consistently usually raises uniqueness scores by 20–40 percentage points while producing clearer, more convincing writing. The goal is not just to “beat” the plagiarism checker — it is to produce work that genuinely reflects your understanding.

How accurate is the plagiarism checker?
The tool scans your text against web sources, books, and academic papers and highlights matching passages with a similarity score. It is designed for a fast originality check, not as a replacement for institutional systems like Turnitin.
Are my documents stored after the check?
No. Texts submitted for a standard check are not stored in a public database and are not shared with other users.

Plagiarism checking and AI detection are separate tools. Use the AI content detector if you want an estimate of whether a text was written by a language model.
