Key Pointers
- Grammarly’s plagiarism checker is a Premium (paid) feature. The free version of Grammarly does not include plagiarism detection.
- Grammarly offers a free trial in some cases, and short-term promotional access sometimes surfaces through school or work signups. There’s no permanent “free forever” version of the plagiarism checker.
- The typical workaround people search for (a free way to use Grammarly’s plagiarism checker) usually leads to either the trial route or a third-party alternative that actually is free.
- Quetext is the closest actually-free alternative. The plagiarism checker covers the first 1,000 words free per scan, and the same platform includes AI content detection in the same pass.
- For students working under a deadline, the practical answer is usually to skip the Grammarly trial hoops and run the check through Quetext instead.
The Short Version
Grammarly’s plagiarism checker is a paid feature bundled with Grammarly Premium. You can access it through a free trial or occasional promotional signups, but there’s no permanent free version. If you need a plagiarism check right now without paying, the fastest path is to use a tool that’s actually free. Quetext’s Plagiarism Checker covers the first 1,000 words free, includes AI content detection in the same scan, and doesn’t require a trial signup or credit card. For most students searching for a free way to check their paper, that’s the shorter route.
Is Grammarly’s plagiarism checker free?
Short answer: no, not on the free plan.
Grammarly has two main tiers. The free tier includes grammar, spelling, and basic writing suggestions. The Premium (paid) tier includes advanced writing feedback, tone suggestions, and the plagiarism checker.
If you install Grammarly today and paste your paper in, you get grammar and spelling checks. You do not get a plagiarism scan until you either upgrade to Premium or start a trial.
This is what usually confuses people. Grammarly’s marketing across the site talks about the plagiarism checker as a Grammarly feature, and search results treat it as one of Grammarly’s main capabilities. Both of those are true. It’s just a paid Grammarly capability, not a free one.
What “Grammarly’s plagiarism checker free” search results actually lead to
A few paths people usually find when they search for this.
Grammarly Premium free trial. Grammarly occasionally offers a free trial (typically a few days) that includes the plagiarism checker. You sign up with a credit card, and the trial converts to a paid plan if you don’t cancel. Trial availability changes, so check Grammarly’s pricing page for current details.
Student or school signups. Some universities have institutional Grammarly access that includes Premium features. If your school has this, you can log in with your school email and use the plagiarism checker as part of the institutional plan. Whether your school offers this varies. Check with your IT department or writing center.
Employer or organization signups. Similar to student access, some employers provide Grammarly Business seats that include Premium features. Same rule: check with your organization.
Third-party workarounds. Various guides on the web describe workarounds like temporarily upgrading, using the plagiarism check, then downgrading before billing. These often violate Grammarly’s terms of service and aren’t a good long-term option.
Actually-free alternatives. The last category is what most searches for “Grammarly plagiarism checker free” ultimately lead to. Tools that aren’t Grammarly but offer plagiarism checking in a genuinely free tier, without a trial signup or credit card.
The trial route: how it actually works
If you want to try Grammarly Premium’s plagiarism checker specifically, the trial route works like this:
Step one: Go to Grammarly’s pricing page and check if a free trial is currently offered. Availability varies.
Step two: Sign up with a credit card. Trials require payment info even though you’re not immediately charged.
Step three: Install Grammarly (browser extension, desktop app, or use the web editor at grammarly.com).
Step four: Paste or upload your document. Run the plagiarism check from the Premium features menu.
Step five: Cancel the trial before it converts to paid if you don’t want to keep the subscription.
Two things to know. First, the credit card requirement means you have to remember to cancel. Second, the trial length varies, so check the current terms before signing up.
For most students, the trial route works if you’re okay with the signup and cancellation cycle. If that friction sounds like more trouble than it’s worth for a single plagiarism check, the actually-free alternative is usually the better call.
Quetext: the actually-free alternative
If you want a free plagiarism check right now without signing up for a trial, Quetext is the closest fit for the use case. Three reasons.
No trial signup or credit card required. Quetext’s free tier is genuinely free. You paste your text, you get the scan. There’s no credit card ask and no clock running down to a paid conversion.
1,000 words free per scan. The free tier covers 1,000 words per scan, which handles most essays, short papers, and blog drafts. For longer papers, Quetext offers paid plans that unlock full-document scanning.
Bundled AI content detection. In 2026, most professors and reviewers care about both plagiarism and AI-generated content. Quetext’s scan returns both signals in the same pass, so you don’t need a second tool for the AI check.
Same scan technology as the paid product. The 1,000-word free scan uses the same DeepSearch technology as Quetext’s paid plans, scanning against billions of web pages and academic sources. It’s not a stripped-down free tier.
For students who need a check today and don’t want to book a trial signup, Quetext handles the job in about the time it takes to paste the text.
Try this: Skip the paywall, check your paper free with Quetext. The first 1,000 words are no-cost, and the combined plagiarism plus AI scan covers what most students actually need to check.
Grammarly vs. Quetext for plagiarism specifically
For students weighing whether to go through the Grammarly trial or use Quetext directly, three practical comparisons.
Scan depth. Both tools scan against large web indexes. Grammarly’s Premium plagiarism check and Quetext’s DeepSearch both handle the coverage needs of typical student papers.
AI content detection. Quetext returns AI content detection in the same scan. Grammarly has AI detection features across its writing suggestions, but they’re not fully bundled into the Premium plagiarism check the way Quetext’s are. For students who need both signals, Quetext’s bundled scan is the shorter path.
Cost model. Quetext’s free tier is free without a trial. Grammarly’s plagiarism check requires either a paid subscription, a free trial with credit card, or institutional access.
Additional features. Grammarly Premium includes grammar, tone, and style suggestions on top of plagiarism. If you also want those writing suggestions, Grammarly is doing more than just the plagiarism check. If you only want the plagiarism check specifically, Quetext is the shorter answer.

Bonus: how to use Turnitin free
If you’re also looking for free access to Turnitin (which is a common companion question), our how to use Turnitin free guide walks through the routes that actually work. Short answer: Turnitin doesn’t have a free consumer tier, so the paths are institutional access, indirect drafts through your school’s plagiarism check services, or an actually-free alternative like Quetext for the pre-submission check.
What to do with the scan results
Whether you use Grammarly, Quetext, or another tool, the scan is only useful if you know what to do with the output.
Flagged passages with clear matches. Rewrite in your own framing or add a citation. Both are valid resolutions. Editors sometimes forget the citation is a resolution, not just a rewrite requirement.
Flagged passages that are legitimate quotes. If the match is a quote you cited correctly, the flag is fine. Move on. Not every match is a problem.
Flagged passages that are industry-standard phrasing. Some phrases (methodology sentences, technical descriptions, standard definitions) show up across many sources. If your version is your own writing that happens to overlap with standard phrasing, the flag is often noise.
AI-generated content flags. If your paper has AI-generated content that’s flagged, and your class policy allows AI use with disclosure, add the citation and disclosure. If your class policy prohibits AI, remove or rewrite the AI-generated sections.
For most students, the scan surfaces one or two real issues, plus a handful of noise. Addressing the real issues and ignoring the noise is what matters.
Wrap-up
Grammarly’s plagiarism checker is a paid feature. There’s no permanent free version, but there is a free trial route if you’re willing to sign up with a credit card and remember to cancel. For students who don’t want to deal with the trial signup and cancellation cycle, Quetext offers a genuinely free plagiarism check on the first 1,000 words per scan, with bundled AI content detection in the same pass.
For students who also want grammar and style suggestions on top of plagiarism checking, Grammarly Premium bundles all of that together. For students who only want the plagiarism check specifically, Quetext handles it faster and without the paid signup.
Either way, the actual value is what you do with the scan results, not just which tool you ran the scan through. Address the real matches, ignore the noise, and cite your sources correctly the first time.
Try Quetext free if you need a plagiarism check today without a trial signup. The first 1,000 words are no-cost, and the combined plagiarism plus AI scan covers the checks most students actually need before submitting.

Is Grammarly or Quetext more accurate for plagiarism?
The two services offer similar plagiarism detection features for students’ assignments. The differences between the services boil down to AI detection (Quetext has AI functions included in the scan; Grammarly has AI functions outside of the scan) and pricing (Quetext is free with no trial needed; you have to pay or sign up for a trial for Grammarly). For the cases of most students, however, what matters more is ease of access to the service when they need it.
