The short answer
There is no Turnitin checker you can buy. Turnitin’s help centre says it does not sell individual licenses or single-use subscriptions. Your options are your school’s Turnitin, iThenticate for manuscripts, or a separate checker.
Three real ways to check
| Route | Is it Turnitin? | Cost to you | Best for |
|---|---|---|---|
| Your school: a draft submission or Draft Coach | Yes | Paid by the school | Students whose school offers it |
| iThenticate | A Turnitin product, sold to individuals | $125 for one manuscript up to 25,000 words | Researchers preparing work for publication |
| An independent checker | No | Free checks with limits, then paid plans | Finding passages you forgot to quote or cite |
Start with your school. Ask your instructor, library or IT help desk. Turnitin’s Draft Coach FAQ says Draft Coach is an add-on for Google Docs or Microsoft Word online, and that it depends on the school’s licence. See is Turnitin free? for prices and access.
What Turnitin searches, and why scores differ
Turnitin’s product page says it compares work with a repository of student papers, current and archived web pages, and subscription articles from publishers. No other tool can search those student papers. That is why no independent checker can predict your score.
- Turnitin can match a paper another student submitted. A web-based checker cannot.
- What the number means. See Turnitin similarity score.
- AI results are separate. See does Turnitin detect AI?
Be careful with sites that look like Turnitin
Some websites use Turnitin’s name in their own name or address. Some offer a “Turnitin report” for a fee. Turnitin says it does not sell individual access, so these are not official routes.
- Check who owns the site. A name is not proof.
- Ask what happens to your paper. Read the privacy policy before you upload.
- Do not trust a promise of the same score. No outside tool can make that promise honestly.
How to check a paper with an independent tool
- Finish your citations first. A check is more useful on a nearly final draft.
- Run the check. Look at each match, not only the percentage.
- Open each source. Decide if you should quote it, or put the idea in your own words with a citation.
- Fix what is a real problem. A quote with a citation is not plagiarism, even if it matches.
- Follow your course rules on AI tools. A plagiarism check does not cover them.
Our plagiarism checker gives a first check free with no account, up to 1,000 words, and links every match to its source. Our AI detector gives an overall score and a likelihood for every sentence. A score is not proof. A free account includes 3,000 words a month, and Student plans start at $4.99 a month. It has no database of other students’ papers and does not connect to a school system. For help reading a result, see how to interpret a plagiarism report.
