AI Plagiarism Risk Analyzer
Compare two texts; Ryna AI flags similar sentences and quote-like patterns. Note: this is a style/structure compare, not a database check — use Turnitin/iThenticate for definitive verdicts.

Most plagiarism caught at universities isn't malicious — it's accidental. Lifting a sentence from a source and swapping two words, forgetting a citation, or writing a paragraph you're sure is "in your own words" that actually stays too close to the original. Systems like Turnitin flag this as a "similarity score," and most students are shocked by a high number because they didn't think they copied anything. Research suggests a large share of undergraduates can't reliably tell real paraphrasing from "patchwriting" (just swapping words). The problem usually isn't intent — it's never having been taught proper rewriting and citation technique.
Let's be clear: Ryna AI is NOT a similarity checker — it does not and cannot give you a Turnitin-style percentage. What it does is teach. It shows you how to genuinely rewrite a paragraph in your own academic voice, then explains line by line WHAT it changed and why it no longer counts as "too close" to the original. It produces in-text citations and reference-list formatting in APA 7, MLA 9, or Chicago; it helps you decide whether a statement should be a direct quote or a paraphrase, and what counts as "common knowledge" that needs no citation at all.
The output is always a draft and a learning aid — don't blindly copy the citation or paraphrase Ryna gives you; compare it against your own source and verify it in the style your institution requires. Ryna never replaces a certified plagiarism detector; use it to learn how to cite and rewrite, not to get a similarity score. The free plan covers near-unlimited paraphrasing and citation help daily; Plus (399.99 TRY/month) lets you upload the source PDF and your draft and ask "which sentences hug the source too closely, and where are citations missing?", plus use deep thinking and web research to trace a quote back to its original source.
Why use Ryna AI for this
Learn the difference between real paraphrasing and "patchwriting" (word-swapping) through examples — so you catch sentences that stay invisibly close to the source.
Have a paragraph rewritten in your own academic voice and get a "what I changed and why" breakdown — you learn the reasoning, not just the result.
Generate both an in-text citation and a full reference-list entry in APA 7 / MLA 9 / Chicago from a DOI, URL, or source details.
Turn a copied sentence into a proper direct quote: page number, quotation/block formatting, and a fitting signal phrase before it.
Alphabetize your bibliography, fix formatting errors (periods, italics, date placement), and match your in-text citations to the reference list.
Decide whether a statement needs a citation at all: what counts as "common knowledge" versus what must be sourced.

How it works — step by step
- 1
Bring the source and your draft
Open chat.rynaai.com. Paste the original text you want to rewrite and your own draft if you have one; state your citation style up front (APA 7, MLA 9, Chicago). On Plus you can upload the source article as a PDF and have it assessed alongside your draft.
- 2
Ask for a paraphrase — with an explanation
Say: "Rewrite this paragraph in my own academic voice and explain what you changed and why." Don't just ask for the result; learning the reasoning is what lets you write the next paragraph correctly yourself.
- 3
Settle the quote-vs-cite decision
For each statement, ask: should this be a direct quote, a paraphrase, or can it stay uncited as common knowledge? Convert anything you'll use verbatim into a proper quote with a page number and signal phrase.
- 4
Format and match the bibliography
Format your sources in your required style, alphabetize them, and check that every in-text citation matches an entry in the reference list. Have Ryna flag missing fields (year, page, DOI).
Example: input → output
You ask
Rewrite this paragraph in academic language in my own words, then explain what you changed and add the APA 7 citation. Source: Yilmaz (2021), p. 47. Original: "The rise in social media use has shortened attention spans in young people, and this negatively affects academic success."
Ryna AI returns
First, a clear disclaimer: Ryna is not a similarity checker — still compare this paraphrase against your own source and run the final check in Turnitin. Paraphrase (in your own academic voice): Intensifying social media habits are argued to reduce young people's capacity for sustained focus, which in turn lowers academic performance (Yilmaz, 2021, p. 47). What I changed and why: 1) I inverted the sentence structure (reordered cause and effect) — merely swapping words would be 'patchwriting.' 2) I restated the concepts: 'rise in use' → 'intensifying habits,' 'attention spans' → 'capacity for sustained focus' — conveying the meaning, not memorized synonyms. 3) I grounded the claim with 'are argued to' and a citation — even a paraphrase needs one. Citation note: Because this is Yilmaz's idea, an in-text citation (Yilmaz, 2021, p. 47) is required even in paraphrase. Want me to build the matching APA 7 reference-list entry too?
Pro tips
- Ask Ryna to write the "too close (patchwriting)" and the "proper paraphrase" versions of the same sentence side by side — you'll see exactly where the line is.
- Paraphrasing does NOT remove the need to cite. Even in your own words, if the idea is someone else's, it needs a citation; make it a habit to tell Ryna "add the correct citation after the paraphrase too."
- Naming the style isn't enough — name the edition: APA 7 formats differently from APA 6. Specify whichever your institution's guide requires.
- Avoid the secondary-source trap: if a blog quotes a study, use Plus's web research to find the original article and cite THAT — a 'as cited in a blog' reference is weak and may be wrong.
- Have Ryna flag sentences that are "so specific they must have a source" — numbers, dates, and original claims usually need a citation; general truths don't.
- Keep a quote/paraphrase log while researching: record the source and page for every note on the spot. The later 'where did I get this?' crisis is the most common cause of accidental plagiarism.
Common mistakes to avoid
- ✕Mistaking word-swapping for paraphrasing: dropping in synonyms while keeping the sentence structure (patchwriting) is still plagiarism — you must grasp the idea and rebuild the structure entirely.
- ✕Skipping the citation because you paraphrased — even in your own words, if the idea is someone else's, a citation is required.
- ✕Treating Ryna as a similarity checker and expecting a percentage: Ryna can't give a certified score like Turnitin; run the final check with your institution's tool.
- ✕Citing a secondary source: crediting a study that an article merely quotes, without seeing the original — it's both weak and possibly inaccurate.
- ✕Forgetting the page number on a direct quote, or failing to match in-text citations to the reference list — formatting gaps cost marks too.

FAQ
Does Ryna give a similarity score like Turnitin?
No. This is an academic-integrity disclaimer: Ryna is NOT a certified plagiarism/similarity detector and cannot give you a percentage. Use it to learn how to cite, paraphrase properly, and quote; always run the final similarity check with the official tool your institution provides (e.g., Turnitin).
Is using AI to paraphrase considered plagiarism or academic misconduct?
It depends on your institution. Many universities have a written AI-use policy, and some require you to disclose AI assistance. Use Ryna as a learning and drafting aid, rewrite the output in your own understanding, and follow your institution's rules and the assignment brief; if unsure, ask your instructor.
Which citation style should I use?
Your department or assignment brief decides — APA is common in social sciences, MLA in literature/languages, Chicago in history and some fields. Tell Ryna the style and edition (e.g., APA 7) up front so it formats consistently.
I paraphrased — do I still need to cite?
Yes. Paraphrasing only restates an idea in your own words; if the idea is someone else's, an in-text citation is required. The only exception is statements that genuinely count as common knowledge.
When should I quote directly versus paraphrase?
Quote directly when the author's exact wording, a definition, or a striking phrase is essential (quotation marks + page number); paraphrase when you just need to fold the idea into your text. As a rule, use direct quotes sparingly — most academic writing relies on paraphrase.
