Beyond a Percentage

Way more useful than just a percentage. Every time checking my written materials, I can see the exact sources that match and fix the overlap right there.

Well-rounded Writing Support

As an ESL student, I accidentally paraphrase too closely sometimes. This catches it before my professor does and helps me understand which parts need more work.

Pre-submit Review and Check

I use Solvely before submitting longer essays because it shows where the overlap actually appears. It feels much more useful than just seeing a single score.

Clear Source Matches

The matched source cards make the report easy to understand. I can quickly see which passages need a citation, a rewrite, or just a closer review.

Safer Paraphrasing

I often rewrite from research notes, and sometimes my wording stays too close to the source. Solvely helps me catch those parts before I turn anything in.

Submission Confidence

I check every paper for plagiarism here before Turnitin. The match cards make it obvious what I still need to cite or rewrite, especially when I'm rushing before a deadline.

FAQ

Is this plagiarism checker free?

Yes - you can check your text for plagiarism for free once. Paste your content, run the scan, and see your similarity report without paying.

What is a plagiarism checker?

Plagiarism checker is a tool that scans your writing for possible overlap with existing sources. It helps you identify duplicate text, missing citations, close paraphrasing, and sections that may need quotation marks or stronger attribution.

Can paraphrased text still be plagiarism?

Yes. Paraphrasing changes the wording, but the original idea still belongs to the source. If your sentence is based on someone else's argument, data, research, or wording, you still need to cite it.

Is plagiarism checking the same as AI detection?

No. Plagiarism checking looks for similarity with existing sources. AI detection estimates whether text may appear AI-generated. For AI-assisted drafts, it is useful to run both checks before submission.

Can I upload a document to check plagiarism?

Yes. Pro users can upload PDF, DOCX, or TXT files and check the full document in one go. No need to copy and paste section by section - Solvely processes your uploaded file and returns a similarity report for it.
