With the wealth of online content, avoiding unintentional plagiarism is tricky. Fortunately, free plagiarism checker apps can help students ensure assignments are original before turning them in. 

This guide covers the top free plagiarism detection tools and how to use them properly.

Why Students Need a Free Plagiarism Checker

Plagiarism remains a significant issue in academics, intentional or not. According to surveys, over 80% of students admit to inadvertent plagiarism. Accidentally copying sources happens quickly with so much content online. 


That’s why utilizing a free plagiarism app is essential. Free plagiarism checkers scan submissions and highlight copied text from existing works. This allows students to properly paraphrase, quote, and cite sources to avoid plagiarism allegations. 


Quality checkers compare writing against billions of web pages, journals, and papers to identify duplication. While plagiarism apps should not replace learning proper research and citation methods, they provide a critical last check. 


Utilizing them helps students confidently submit original, ethically sourced work. Now let’s examine the top free plagiarism checker options for students.

Best Free Plagiarism Checker Apps

DupliChecker offers a basic free plagiarism scanner supporting text up to 5000 words. It checks writing against previous submissions, abstracts, and publications in its existing database.


The tool highlights duplicate passages found and provides an overall plagiarism percentage. Students can interpret if that percentage seems reasonable given the amount of quotes and citations needed in the work.


DupliChecker also provides a Chrome extension to instantly check webpages. Its bulk uploading makes it easy to scan multiple assignments.



4. Plagiarisma

Plagiarisma’s free plagiarism tool allows students to check short excerpts of writing for duplication. Just paste in a fragment or sentence at a time to see if it appears elsewhere online.


Given the limited text length, it's best for spot-checking specific passages rather than whole papers. But it's handy for quickly verifying if a particular phrase needs rewriting.


Plagiarisma also offers a $5 per month subscription for full-document scans if needed. But its free version works for targeted checks during the editing process.


5. PlagScan

The tool highlights copied passages and generates an originality report with the percentage of unique content. PlagScan integrates directly with Google Drive for easy uploads.


While geared toward academic institutions, students can still benefit from the free trial. Just be sure to cancel ahead if not wanting to subscribe after the trial.


6. Plagiarism Checker by SmallSeoTools

This web-based tool lets students run up to 1500 words through its plagiarism scanner for free. It searches across major search engines and online publications.


The report highlights duplicated text and identifies the online source. This helps students properly cite passages that should not be paraphrased. Reports can be emailed for later reference while rewriting.


For longer submissions, SmallSeoTools offers paid plans starting under $5 monthly. But the free version sufficiently covers standard short essays and assignments.



4 Pro Tips for Using Plagiarism Checkers Effectively

While plagiarism checkers are invaluable for students, keep these expert tips in mind to use them effectively:


1. Set Realistic Expectations

No plagiarism app is foolproof at detecting all duplication issues. Technical workarounds exist allowing intentional plagiarists to slip past scanners. So don’t rely on apps as the only defense against plagiarism.


2. Check Early in the Writing Process

Run initial scans when drafting so there is time to properly rewrite or cite flagged passages before completion. Checking only right before submission leaves little room for improvement.

3. Assess the Context of Flagged Matches

A sentence may show up elsewhere online but still not require citation if it’s common knowledge or a generic phrase. Check flagged results to determine if referencing is truly needed based on academic guidelines.

4. Balance Paraphrasing with Quotes

Blindly rewriting everything flagged can weaken writing quality. Use quotes strategically for key passages while paraphrasing generic descriptions in your own words. This results in a well-cited, high-quality paper.

Using plagiarism checkers strategically helps students hone their writing skills, not circumvent them. The apps serve as extra assistance on top of citing best practices learned in class.


Why Plagiarism Remains a Major Concern for Students

Even with good intentions, students often struggle to avoid plagiarism for reasons like:


  • Stress and workloads make cut-and-paste quotes tempting
  • Lack of confidence in expressing concepts in one’s own words
  • Misunderstanding when a citation is required for a passage
  • Having a naive sense that rewording equals no plagiarism
  • Waiting until the last minute leaves no time to rewrite the flagged text


Quality-free plagiarism checkers combined with proper time management alleviate these challenges. But students also build long-term skills by learning when and how to properly integrate outside sources.


Plagiarism Checklist Before Submitting an Assignment

After the plagiarism scan, students should manually check their work using this best practice checklist:


  • Fact-check quotes, data, and source material for accuracy
  • Verify formatting of both in-text and bibliographic citations
  • Review paraphrasing quality to ensure definitions are fully reworded
  • Check common knowledge statements are not incorrectly cited
  • Scan for citations needed for images, tables, and appendices
  • Compare reference list to in-text citations for completeness
  • Examine paper structure to confirm the logical flow of sections
  • Read aloud for catching any awkward patches needing rewrite


The most robust plagiarism defense combines scanner apps with learned research and documentation skills. Following a methodical checklist removes reliance on technology alone.


Frequently Asked Questions About Plagiarism Checker Apps

Are free plagiarism checkers accurate?

Free checkers scan against limited databases, so paid services offer greater detection capability. But free tools sufficiently uncover blatant, word-for-word plagiarism from major online sources in most student work.


Can plagiarism checkers save as reports?

Most free tools allow saving PDF reports containing the percentage of unique content and highlighting copied text passages and their online source. Students can refer back to these reports while revising their work.


Do professors use plagiarism checkers?

Many institutions license robust plagiarism scanners allowing professors and teaching assistants to check student work. So it’s important students run the same checks proactively before submitting assignments.


What if plagiarism is unintentional?

Schools may be more lenient when plagiarism appears accidental due to a lack of citations rather than deliberate copying. But it still carries academic dishonesty penalties. So unintentional plagiarism should be treated just as seriously.


Can you trick plagiarism checkers?

Changing words in a plagiarized text to synonyms and scrambled word order are common tricks students attempt. But most detectors account for this by scanning for sentence structure and context rather than matching keywords only.





With the right plagiarism tools and research habits, students can confidently submit original, ethical work. Free scanner apps catch overlooked duplication issues early when revision time remains.


But they should be used to complement, not replace, a solid understanding of proper quoting, paraphrasing, and citation guidelines.


Plagiarism remains a challenging academic issue. But equipping students with the best free tools and education fosters work students can take pride in as their own.
