I was cramming to finish my research paper and needed to make sure everything was properly cited. Smodin's Plagiarism Checker gave me peace of mind in just a few minutes! It caught a couple of sentences that were too close to the source, so I reworded them before submitting. Super easy to use and surprisingly fast. Definitely keeping this in my toolkit for future assignments.

I always stress about plagiarism, even when I know I wrote everything myself. Smodin helped me double-check my work without any hassle. The interface is clean, and the results come back fast. I compared it to my school's checker, and Smodin actually caught a few things that the other one missed! It's been a help especially from big research papers.

How To Avoid AI Plagiarism Detection

Using generative AI like Smodin’s Writer to create content is becoming the norm because of its speed and quality. However, it's important to review and refine this work to ensure it meets high standards and to detect plagiarism.

This is due to patterns in the use of words and sentences. They are also prone to repetitive themes, sentences, and strange grammatical structures. If your writing matches these patterns, these tools falsely identify your work as AI plagiarism.

Smodin’s AI Content Detector looks for these signs, and with the Rewriter tool, you can avoid these pitfalls easily. Thanks to the continuous improvement of its algorithms, your writing gets a human touch.

Check Plagiarism

The importance of checking for plagiarism

When you pour hours, days, weeks, or months into your work, it’s natural to assume your content is original. However, this is usually not the case, as similar ideas or content will likely be online.

Publishing such work without checking for content plagiarism can have legal, financial, and personal consequences. It also damages your reputation due to accusations of copying. You must verify your content’s originality and add citations where necessary.

📋 Keep Track of Sources

Always list all the sources you use while gathering information for your work. Citing your sources ensures your content passes plagiarism detection successfully.

☑ Use a Plagiarism Checker Before You Submit Your Work

After completing your work, you must do a final review with a plagiarism detector. This helps detect unintentional copying, which you can correct before submission.

❝ Paraphrase or Quote Sources

If you need to quote anything directly, include it inside quotes or brackets. Otherwise, it will appear as plagiarism. You can also paraphrase the statement or work to avoid detection.

🔄 Use a Rewriter or Idea Generator for Assistance

Paraphrasing is challenging, especially when the content isn’t in your first language. It can also take loads of time if you’re out of ideas or facing writer’s block. Smodin’s Rewriter tool helps avoid plagiarism by paraphrasing any text to ensure it is unique without changing the meaning.

Recommendations

Recommendations When Looking for Plagiarism

Use Large Amounts of Text

It's easier to check for plagiarism accurately with large amounts of text. Due to this reason, always include as many paragraphs or pages as possible.

Keep Similar Content Together

Avoid separating similar content, as this increases the likelihood of false positives. You must combine similar content, as this improves the quality of the search results.

Avoid Searching for Generic Phrases

Generic phrases are popular and will appear in any free plagiarism detector.

Avoid Searching for Short Phrases

Short phrases are easier to detect as they're likely to contain a series of words identical to another person's work.

Avoid Searching for Cited Sources

A free plagiarism checker searches the internet to find similarities in your content with other people's work. Any source you cite will appear in the search results and test positive for plagiarism.
