The tool
What the DeepSeek paraphraser does
The DeepSeek paraphraser restates a passage in different words. You paste it, the text goes to our AI server, and the reworded version comes back on its own, with no preamble, commentary, quotation marks or markdown fence attached. Five free runs per rolling 24 hours, 1 to 12,000 characters each, no account and no card.
That character allowance is worth comparing with the category. One paraphrasing tool checked while researching this page gives four runs in total on its free tier, at 250 words per run, and its paid plan at 18 dollars a month allows 1,000 words per run. Twelve thousand characters is a long way past that, and it is free.
How to
How to paraphrase a passage in three steps
Simple to operate. The thinking is in what you do before and after.
- Step 1
- Read the original until you could explain it without looking. If you cannot, a paraphraser will produce something that sounds right and misses the point.
- Step 2
- Paste it and name your constraints in the instruction field, up to 300 characters. Keep the technical terms, keep the reference in brackets, do not strengthen the claim.
- Step 3
- Check the result against the source on facts and certainty, then add the citation. The citation is the step the tool cannot do for you.
The distinction
Paraphrase, summary or quotation
Three different operations get confused with each other, and picking the wrong one is behind most of the trouble people get into. All three need a citation when the idea is not yours.
- Quotation
- The original words, in quotation marks, with the source. Use it when the exact wording is the point, or when the author said it better than you will.
- Paraphrase
- The same idea at roughly the same length, in your own construction. Use it when you need the detail but not the voice.
- Summary
- The idea, much shorter, in your own construction. Use it when the detail does not matter to your argument.
- What all three share
- The obligation to say where the idea came from. Rewording changes the sentence, not the provenance.
The real risk
Patchwriting is still plagiarism
This is the thing a paraphraser page should tell you and mostly does not. Patchwriting is taking a source passage, swapping out 30 to 40 percent of the words, restructuring two or three sentences, and submitting the result as your own paraphrase. One of the pages read while researching this route describes it exactly that way, and says it violates the academic honesty policies of essentially every US, UK, Canadian and Australian university.
The reason given is the important part: even with the citation present, the underlying sentence structure and argumentative skeleton is still the source author's. So a light pass through any paraphrasing tool, this one included, does not make a passage yours. If the result still walks through the source's points in the source's order, you have patchwritten, whatever the word overlap says.
Honest limits
What this paraphraser does not do with your citations
There is nothing in this tool that understands a citation. It does not detect a parenthetical reference, a footnote number or a bracketed numeral, and it does not reattach anything to anything. Some competitors advertise citation preservation as a feature. We do not have it, so we do not claim it.
What you can do is ask. Put keep every bracketed reference exactly where it is into the instruction field, then read the output and check each one by eye. That works often enough to be worth doing and is not a guarantee, which is the difference between an instruction and a feature.
The common case
Paraphrasing your own writing is a different question
Most people using a paraphraser are rewording their own draft, not somebody else's source. Nothing in the integrity discussion applies to that. You cannot plagiarise yourself into a rule violation by rephrasing your own paragraph for a different audience.
For that case the useful instructions are practical rather than ethical: shorter, plainer, less formal, keep the defined terms. The check afterwards is the same one, though. Confirm the figures and the degree of certainty survived, because a paraphrase that turns may into will has changed your claim regardless of who wrote the original.
The honest answer
Will paraphrased text get past Turnitin?
We do not know, and we will not guess. Turnitin, Copyleaks, GPTZero and Originality.ai are other companies' products with their own indexes, thresholds and release schedules, none of which we can see. We are not affiliated with any of them and we predict no result from any of them.
There is also no similarity index in this tool at all, so nothing here compares your text against existing content. If your question is whether a passage will be flagged, that is a question for a service with a corpus, and the better question is whether the passage is actually yours. Patchwriting that slips past a checker is still a policy breach if anyone reads it properly.
In practice
Who uses the DeepSeek paraphraser
Researchers restating a finding in their own register. Writers who have quoted too much and need to convert half of it to prose. People writing in a second language who understand the source perfectly and want a different construction for it.
That last case is worth naming, because it is the most common honest use of a paraphraser and the one most likely to be treated with suspicion. Understanding a source and struggling to restate it in English are different problems, and only one of them is an integrity issue.
