AI Detector
How do I check my text for AI writing?
- Open AI Detector.
- Paste your text or select Upload file.
- Check that the text meets the displayed word limits, then select Scan.
- Review the score, highlighted passages and available explanations.
To check the same text for source matches as well, choose Comprehensive Scan. It displays the two results in separate tabs and needs enough allowance for both tools.
What does the AI score mean?
The score estimates how strongly the writing resembles AI-generated text. A higher score means stronger signs of AI writing in the assessment. It is not proof of authorship or the percentage of words definitely written by AI.
Labels such as Human Written, Mixed, Likely AI and AI Generated are score categories. Read the findings alongside the text and what you know about how it was written.
How can I see why text was highlighted?
Hover over or select a highlighted passage to see its available details. Under Detected AI writing patterns, select Highlight matching text to locate passages linked to an explanation. Select the control again to clear that pattern highlight.
Repeated findings are grouped together. Some passages may have limited context or no clear pattern, so every passage will not have a detailed explanation.
Why are some writing patterns locked?
Free access may show a limited preview. Select Unlock all to see the available paid-access options.
When a saved report still contains the findings, eligible paid access can reveal them without another scan. Upgrading cannot restore report content that has already been deleted.
Which languages can I check?
The detector has dedicated support for English, Swedish, Finnish, German, Dutch, French, Italian, Polish, Spanish and Portuguese. It identifies the language automatically, so there is no language menu to set before scanning.
Paste the original writing without translating it first. Other languages or mixed-language text may receive a general assessment. The level of detail and reliability can vary by language and type of writing
Can human writing receive an AI score?
Yes. Human writing can share patterns with AI-generated writing, and AI writing can go undetected. A detector result alone cannot settle who wrote a document.
If a result raises questions, review the passages and consider drafts, notes, sources and the writer’s explanation. Do not base an academic or employment decision on the score alone.
Why did the score change when I scanned again?
A fresh assessment can produce a different result. Changes to the text, its length or the tool can also affect the score. Opening a saved report shows its saved result; selecting Rescan runs a new assessment and uses allowance.
Keep the original report if you need to compare checks. Focus on the explanations and passages as well as the numbers.
Can the detector tell me which AI model wrote the text?
The report assesses signs of AI writing. It does not reliably identify a particular model or prove that a writer used ChatGPT or another service.
Likewise, a low score does not prove that no AI was used. Use the report as one part of your review.
Plagiarism Checker
How do I run a plagiarism check?
- Open Plagiarism Checker.
- Paste your text or select Upload file.
- Open the scanner’s Configure options if you want to adjust the assessment.
- Select Scan, then review Matching sources and the highlighted passages.
What does the similarity score mean?
It summarises the text overlap found with sources returned by the scan. A match can be a correctly quoted passage, a citation or common wording; it does not automatically mean plagiarism.
Read each source in context. Source percentages can overlap, so adding them together may not give the overall score. There is no single acceptable percentage for every assignment or publication.
Does a score of 0% mean my work is completely original?
No. It reflects the results of that scan, with the current settings and available sources. Very small matches can also round down in the displayed score, so check the source list even when the score is zero.
The checker cannot guarantee access to every book, private document or page behind a login. Heavily paraphrased material may not be found, and borrowed ideas still need appropriate credit.
How do I review a match or an estimated result?
Select a source in the results to focus on its matching text. Use Open source, where available, to compare the wording and check your attribution.
Estimated result means some details could not be fully compared. Potential match highlights use the available source information and need closer review. Check whether a passage needs a citation, quotation marks or a clearer distinction between your ideas and the source’s.
What does Deep Search do?
Deep Search compares matching sources in greater detail. Turn it on before scanning if it is included with your paid access.
It applies to the plagiarism check, including within Comprehensive Scan. It does not affect the AI assessment or guarantee that every possible source will be found.
Can I exclude references and citations?
Open the scanner’s Configure options. Exclude references leaves recognised reference lists and bibliographies out of the assessment. Exclude in-text citations leaves out recognised citation markers, such as an author and year or a numbered reference.
The surrounding sentences and quoted passages remain part of the check. Enough assessable text must remain after exclusions. All submitted words still count toward your allowance.
Can I exclude my own website or another domain?
With eligible access, turn on Excluded websites, enter a domain such as example.com, and select Add website. Apply the changes before scanning.
You can add up to 50 domains. An excluded domain includes its subdomains; the setting does not exclude just one page. Adding an address to the input box is not enough—you must add it to the list. Website exclusions affect assessment, not word usage.
Writing Tools
Which writing tool should I choose?
| Tool | Use it when you want to |
|---|---|
| Text Rewriter | Express a passage differently or change its tone. |
| Text Humanizer | Improve awkward wording, repetitive sentences and the flow of a draft. |
| Grammar Checker | Correct grammar, spelling and punctuation. |
The tools suggest revised text. Review the result and keep the changes that suit your meaning and voice.
How do I use the Text Rewriter?
Paste your draft into Original Text, then choose Select tone. Pick Professional, Casual, Creative, Persuasive, Friendly or Academic, and select Save Settings.
Select Rewrite. Review Rewritten Text, then select Copy to use it in your document. The selected tone guides this editing session; it is not an account-wide default.
How do I use the Text Humanizer?
Paste your draft into AI Text and choose Select intensity. Select an option and choose Save Settings, then select Humanize.
- Light: targeted changes to wording and flow.
- Medium: broader improvements to awkward sentences, repetition and transitions.
- Heavy: more extensive changes to sentence structure within paragraphs.
Review Humanized Text and select Copy to keep it. Intensity controls the extent of editing; it does not guarantee any particular detector score.
How do I use the Grammar Checker?
Paste your draft into Your Text and select Check Grammar. Review Corrected Text, then select Copy.
The result is a revised passage. The current tool does not provide tracked changes, an explanation of every correction or individual accept-and-reject buttons
Can I use the writing tools in another language?
The Humanizer has language-specific editing support for English, Swedish, Finnish, German, Dutch, French, Italian, Polish, Spanish and Portuguese. It aims to preserve the language and meaning of your text.
The Rewriter and Grammar Checker do not have a language selector. Review any output carefully for language changes or wording that does not fit your intended meaning.
Will the tools keep my meaning and make my writing ready to submit?
They aim to preserve your meaning, but you should check facts, names, numbers, quotations and citations after editing. A smoother sentence can still contain a factual error or need a source.
Use the tools within your school, employer or publisher’s rules. Editing does not guarantee a particular AI or plagiarism score, and it does not remove the need to credit sources or disclose AI assistance when required.
Are my rewrites and corrections saved in Reports?
No. Reports stores saved AI, plagiarism and Comprehensive Scan results. Rewriter, Humanizer and Grammar Checker outputs are not saved there.
Use Copy and paste the result into your own document before clearing the tool or reloading the page. The writing-tool screens do not offer the report download or sharing controls. To work on text from a document, copy and paste it into the tool.
Reports and Sharing
Where can I find a previous report?
Select Scan reports in the sidebar or Reports in your account menu. Search by report ID or title, filter by scan type, or change the sort order.
Open a report to see its saved findings. This does not run a fresh scan or use more checking words.
How do I turn automatic report saving on or off?
Open sidebar Configure, find Reports, and change Save reports automatically. Select Save changes.
This setting applies to future AI Detector, Plagiarism Checker and Comprehensive Scan reports. Turning it off does not delete existing reports. A result marked Not saved cannot be reopened from Reports or shared through a report link. Download it while it is still open if you need a copy.
If a check completes but its report cannot be saved, download the result before leaving the page. Contact support if saving keeps failing.
How do I rename a report?
Open the report’s actions menu in Reports and select Rename, or use the title-edit control in the open report. Enter a title of up to 160 characters and save it.
Renaming makes a report easier to find. It does not change the scanned text or result.
Can I edit the text and check it again?
Open the report and turn on Edit mode to revise the text. Run the check again when you are ready. Until then, the displayed findings still refer to the previously analysed text.
To run an unchanged text again, use Rescan and confirm. A fresh check creates a new report and uses your allowance. In Comprehensive Scan, finish or retry the outstanding checks before rescanning the complete report.
How do I download a PDF report?
Select Download in the open report or its actions menu. A printable report opens with your browser’s print dialog. Choose Save as PDF, or your browser’s equivalent PDF option, and save the file.
You can also print a paper copy. If nothing opens, allow the report window in your browser and try again.
How do I share a report and turn its link off?
Open an accessible saved report and select Share, or choose Share report from its actions menu. This enables link access immediately. Copy link copies the address so you can send it to your intended recipient.
Anyone with the link can view the read-only report, including retained scanned text and findings, without signing in. Turn Share link off in the sharing dialog to stop access.
Selecting Share again after disabling it enables a new link; turn the switch off again if you only opened the dialog to check it. Disabling a link cannot remove copies someone has already saved.
Why is an old report locked, missing its text or unavailable?
A locked report may be outside the access window for your current plan. Select Unlock all reports to see the available options. Report access follows the owner’s account, including access through shared links.
Missing text can have a different cause: the submitted text may not have been retained, or it may have been removed under the storage policy. Upgrading cannot restore deleted content. Download important reports while they are available, and see our Privacy Policy for storage information.
How do I delete one or more reports?
In Reports, open a report’s actions menu and choose Delete. To remove several, select the reports and choose Delete selected reports, then confirm.
Deletion removes the saved report and stops its share link from working. It does not restore words used for the check. Keep any copy you need before deleting; there is no restore option in the app.
Account and Profile
How do I create an account or sign in?
Select Sign in and continue with your Google account. The same sign-in process creates your PlagScanX account if you do not already have one.
Use the same Google account each time to reach your existing plan, allowances and reports. If you pasted text before signing in, check that it appears in the tool, then start the check when you are ready.
Do I need a separate PlagScanX password?
No. The current sign-in process uses your Google account. If you cannot access that account, use Google’s account recovery process. PlagScanX does not have a separate password-reset form for this sign-in method.
Why am I being asked for an email verification code?
Some sign-ins need an extra email check. Enter the code sent to the email address shown and select Verify and continue.
Check your spam folder if the message is missing. Codes expire after 10 minutes; use Restart Google sign-in if verification expires. If a message says too many verification emails have been requested, wait for the stated period before trying again.
Can I change my name, email address or profile picture?
Open your account menu and select Profile to view your details. These details are not editable on the Profile page. Contact support if your information is incorrect or you need help with the email linked to your account.
How do I change my email preferences?
Open Profile and find Notifications. Use the switches for Email notifications, Usage notifications and Marketing email. Changes save when you use each switch.
Marketing email is off by default. These preferences do not replace messages needed to verify a sign-in or handle a purchase or support request.
How do I delete my account?
Open Profile, find Delete account, and read the confirmation before continuing. Save any reports or writing you want to keep first.
Account deletion ends your access and removes your account’s saved PlagScanX content. Any active subscription renewal must be cancelled as part of the process. You lose remaining paid access and unused purchased words; deletion does not automatically issue a refund. Some records may remain for the reasons explained in our Privacy Policy.
If deletion cannot finish, follow the displayed message or contact support. If you only want to stop future subscription charges, use Manage subscription instead.
Plans and Usage
Can I use PlagScanX for free?
A free account provides the tools and allowances listed in the current plan details. Some features require paid access. A crown or upgrade message means the selected feature is not available with your current access.
Select View pricing, View plans or Upgrade, where shown, to compare the available options.
Where can I see my remaining allowance?
Open your account menu and select Usage. The sidebar also shows a quick summary. Check the allowance for the specific tool you want to use; having words available for one tool does not always mean you have words available for another.
Purchased allowances show their remaining words and expiry dates. You can see your current plan under Profile → Plan.
How are words counted when I run a check?
AI detection and plagiarism checking each use their own allowance. A Comprehensive Scan of 1,000 words uses 1,000 AI detection words and 1,000 plagiarism words when both checks complete.
Excluding references, citation markers or websites does not reduce the submitted words counted toward usage. A fresh scan, including a rescan of the same text, uses allowance again. Opening an existing saved report does not run another check.
When does my allowance reset?
Check the reset date shown for the relevant tool under Usage. Reset schedules depend on your plan and the tool. Your billing date, allowance reset date and purchased-word expiry date can be different.
Use the dates in your account rather than assuming that all allowances reset on the first day of the month. Purchased word balances have their own expiry and do not refill when an included allowance resets.
What is the difference between a subscription and a Pass?
A recurring subscription renews according to the billing period selected at checkout until you cancel renewal.
A Pass, when offered, is a one-time purchase with an end date and no automatic renewal. Check its purchased allowances and expiry in your account. Review the offer for the tools and balances included.
How do extra words work?
If your paid account or active pass is eligible, select Get extra words in Usage or Buy extra words where offered. Review which tools the purchase covers, how many words it adds and when it expires.
The tool uses its included allowance first, then eligible purchased balances in expiry order. Extra words do not remove the maximum word count for an individual request. Check Usage after payment to see the updated balance.
How do I upgrade or change my plan?
Open the pricing options from your account and choose an available plan. If a plan-change preview appears, review the amount due, billing period and allowance details before confirming.
For changes that are not offered in the app, open Manage subscription or contact support. If a preview has expired or the price has changed, request a new preview before continuing.
How do I cancel automatic renewal?
Open your account menu or Profile and select Manage subscription. Follow the cancellation steps in the billing portal and check the confirmation and access-end date.
To stop future renewal while keeping the period already paid for, check that the confirmation shows the intended end date. Contact support if the date is unclear or you need help stopping renewal.
Cancellation, immediate termination and a refund request are separate actions. Cancelling renewal does not automatically refund an earlier charge, and you do not need to delete your account to stop it.
Where can I manage payment details or get help with a receipt or refund?
For a recurring subscription, use Manage subscription to open the billing portal and view its available options. For a Semester Pass or extra-word purchase, check your receipt. Contact support with your account email and order reference if you cannot find the payment detail or receipt you need.
For refund requests, email [email protected]. Our Terms and Conditions and Right of Withdrawal page explain the applicable purchase rights. Do not send your full card number or password.
I paid, but my account has not updated. What should I do?
Make sure you are signed in to the account used for the purchase, then refresh the app. Keep your receipt or payment reference.
If access still has not updated, contact support. If the app says a payment or plan change is pending, or reports a conflicting subscription, ask support to check it before making another purchase.
Settings and Troubleshooting
Where do I save my preferred scan settings?
Open Configure in the sidebar to choose your default report-saving and plagiarism-exclusion settings. Select Save changes and wait for the confirmation.
The Configure inside a scanner applies options to that scan. It does not replace your saved defaults. To include My Library, use this scanner-specific dialog.
Which file formats can I upload for a scan?
AI Detector, Plagiarism Checker and Comprehensive Scan accept TXT, PDF, DOC and DOCX files, one document at a time. My Library has its own upload formats and limits.
Use a document with readable text. Photos, handwriting and image-only PDFs are not converted into text by these tools. If you cannot select and copy the document’s text, obtain a text-based version before uploading.
Why will my document not upload or scan?
Read the error message first. The file may be empty, too large, too complex or unreadable. A document can also exceed the scan’s word limit even when its file size is small enough.
Try copying the text into the scanner or exporting a simpler TXT file. Check the extracted text for missing passages or unusual characters. Do not just rename an unsupported file’s extension.
Why is Scan, Rewrite, Humanize or Check Grammar unavailable?
Check the word counter. Hover over or tap the disabled button to see why it is unavailable. Your text may be below the minimum, above the maximum, or larger than your remaining allowance. The tool may also require a different plan.
For the Rewriter, select a tone. For the Humanizer, select an intensity. Confirm the choice with Save Settings. Wait for any current request to finish before starting another.
Why does Comprehensive Scan say I have insufficient quota?
It needs access to both tools and enough AI detection and plagiarism allowance for the whole text. Check the separate balances shown in the message.
If one check is available, use Continue with AI Detector or Continue with Plagiarism Checker when that option is offered. Otherwise, wait for the relevant reset or review the available plan and extra-word options.
What if one check finishes but the other fails?
In Comprehensive Scan, review each result tab separately. Keep the completed result and use Retry for the failed check when that option appears. A failed or unfinished check is not a zero score.
If the status says processing is still unconfirmed, give it time to update. Do not keep starting new scans. If it remains stuck, contact support with the report ID and message shown.
Are words returned when a request fails?
When processing reports a failure, its reserved words are released. A lost connection or a report-saving error can be different: the check may have completed even though the result did not reach your browser or save to Reports.
Check Usage and, if saving was enabled, Reports before trying again. For a Comprehensive Scan, a successfully completed check still uses its own allowance even if the other check fails. Contact support if the balance or result needs investigation.
What should I do about an expired session, verification error or unavailable tool?
Keep a copy of any unsaved text first. For an expired session, sign in again. If asked to wait before submitting another request, allow the current request to finish before retrying.
For sign-in or security-verification problems, check your connection, allow the site’s required cookies and scripts, and use an up-to-date browser. If a message says the tool, account or verification setup is unavailable, contact support with the exact message. Account-access problems do not mean you need to buy another plan.
If your account is restricted, the access screen still provides Manage subscription, Sign out and Delete account. A restriction does not itself cancel subscription renewal.
Can I use PlagScanX on a phone or tablet?
Yes. Open the site in your browser and use the navigation menu to select a tool. Some controls move below the text on smaller screens. Tap highlighted passages to view available details.
To keep a PDF, use the print or save options offered by your device. Copy writing-tool results into your own document before leaving or reloading the page.
Is my submitted writing used to train AI models?
We do not use submitted writing to train models by default. Text is processed by the providers needed to deliver the selected tool. Saving reports, adding library documents and sharing links have separate effects on how your content is stored and accessed.
Our staff may access submitted content only for support, security, legal needs or a separate purpose you have consented to. Read our Privacy Policy for the full details. Turning off report saving does not stop the processing needed to produce a result.
How do I contact support?
Email [email protected], or select Customer service in your account menu where shown.
Include your account email, the tool you were using, the exact error message and any relevant report or order reference. For display problems, include your browser and device. A screenshot can help, but remove private text you do not need to share. Never send passwords, verification codes or full payment-card details.
