What is Quetext?
Quetext is a web-based originality checker built around its DeepSearch engine, which compares your text against billions of web pages, journals and published works and flags both word-for-word copies and near matches where someone swapped a few words. Alongside the plagiarism scan sits an AI detector that scores text sentence by sentence, plus a citation generator for MLA, APA and Chicago, a grammar checker, a summarizer, a humanizer and the AITutorMe paraphrasing tool. The problem it solves is simple: you need to know, before a teacher, client or editor does, whether a draft borrows too heavily from existing sources or reads as machine-written. The weak spot is coverage. It searches the open web and its own index, not the private student-paper repositories that Turnitin holds, and AI scores on heavily edited text are less certain. Pick it if you are a student, teacher or content writer who wants clear, color-coded reports at a modest price.
How to start using Quetext?
You can try the checker before creating an account. The plagiarism page accepts up to 1,000 words with no sign-up, so paste a paragraph or a short essay, click to scan and you get a score in seconds. A free account adds saved reports, the AI detector, URL exclusion and the combined plagiarism plus AI report. If you work in the browser a lot, install the free Chrome extension as well; Firefox and Edge versions are listed in the site menu too.
Your first real job is usually a full draft. Paste the text or upload a file, choose whether you want a plagiarism scan, an AI check or both, and start the run. DeepSearch processes the text in three stages that Quetext calls contextual analysis, fuzzy matching and conditional scoring. When it finishes, you see an overall percentage showing how much of the text is an exact or near match to something already online. A higher number means more overlap, not automatically more cheating, so read the matches before drawing conclusions.
The report screen is where most of the value sits. ColorGrade feedback paints exact matches, fuzzy matches and AI-flagged passages in different colors, and clicking any highlight opens the matching source side by side in the snippet viewer. From there you can rewrite the sentence, run it through AITutorMe for three alternative phrasings, or press Cite Source to generate a citation in MLA, APA or Chicago format and paste it into your document. If a match comes from your own published page, add that URL to the exclusion list and rescan.
Before you submit or publish, run the final version once more and keep the report. Reports stay in your dashboard under Reports, where you can reopen, download or compare them after edits. On paid plans, Bulk Scan takes up to 20 files on Essential or 100 on Professional, which is how teachers handle a whole class set in one pass. A dated report is also useful evidence if anyone questions the work later.
Scan the final draft, not an early one, and save the PDF of that report before you hand anything over.
Who is it for?
Students
You want to catch a missing citation or a paragraph that sits too close to its source before your professor’s software does. The free tier covers short assignments, and the Cite Source button fixes the gap on the spot. Remember that a clean Quetext score does not guarantee a clean Turnitin score, because Turnitin also checks private paper databases.
Teachers and professors
You review stacks of essays and need a fast first pass for copied text and AI-written sections. Bulk uploads and the Remarks tool on the Professional plan let you scan a batch and leave notes on submissions. Treat the AI score as a reason to talk to a student, not as proof.
Freelance copywriters
Clients increasingly ask for an originality report with every article. Quetext gives you a shareable result in under a minute and a sentence-level AI check, so you can prove the work is yours before the invoice goes out. Keep the dated report, because content scraped after publication can push the score up later.
Content and SEO teams
You publish at volume and need every post checked before it goes live. The Professional plan prices by words rather than seats, adds unlimited users and lets you scale word volume up as output grows. One shared account replaces a pile of individual licenses.
Developers and edtech builders
You want plagiarism and AI detection inside your own LMS, CMS or publishing pipeline. The REST API bills from a prepaid wallet, and the hosted MCP connector lets AI assistants create and fetch reports from a user’s own account. You add checking without building a detection model.
Non-native English writers
You worry that your paraphrasing stays too close to the source. The fuzzy-match highlights show exactly which phrases need more work, and the grammar checker cleans up the rewrite. Be aware that AI detectors in general can misread formal, simplified English as machine text.
Quetext pricing
Quetext sells monthly word allowances rather than unlimited scans. Each plan gives you a fixed number of words for the plagiarism checker and the AI detector, with smaller allowances for the humanizer, summarizer and AITutorMe. Yearly billing cuts the monthly rate roughly in half, and you can buy extra words if a large document goes over your limit. The developer API runs on a separate prepaid wallet.
Plagiarism checks and AI detection up to 1,000 words, the summarizer and humanizer up to 2,000 words, plus the website citation generator and citation assistant. Good enough for a single essay or a quick spot check.
100,000 words per month for both the plagiarism checker and the AI detector, the humanizer and summarizer, bulk uploads of up to 20 files, API access, AITutorMe at 25,000 words per month and the grammar checker. Built for one person writing or grading regularly.
Adds the Remarks tool, bulk uploads of up to 100 files, and 50,000 words each for the summarizer, humanizer and AITutorMe. Word volume scales up with a slider for larger organizations, users are unlimited, and support handles accounts with more than 150 users.
the pricing page lists the plagiarism checker on its own from $9.99/month and the AI detector on its own from $7.99/month, if you only need one of the two.
$0.10 per 1,000 words from a prepaid wallet with no monthly commitment, and every new account starts with 5,000 free words.
Quetext key features
DeepSearch plagiarism detection
The engine combines contextual analysis with fuzzy matching, so it catches paraphrased sentences and patchwork copying, not only verbatim lifts. Results are scored against billions of web, journal and publication sources and usually arrive in under ten seconds. You find the reworded passages that basic free checkers miss.
ColorGrade feedback and snippet viewer
Exact matches, near matches and AI-flagged lines appear in different colors, and each highlight opens its source side by side. Instead of a wall of percentages, you see precisely which sentence to fix and where it came from.
Sentence-level AI detection
The detector looks at word predictability, sentence rhythm and structural repetition, then gives each line a confidence score as well as an overall result. Quetext says it covers output from ChatGPT, GPT-5, Claude, Gemini, Llama and Mistral. You can target edits at specific sentences rather than rewriting the whole piece.
Citation generator and Cite Source
Generate MLA, APA and Chicago citations for journal articles, books, videos and news pieces, or create one straight from a flagged match. Missing or broken citations are a common cause of accidental plagiarism, and this closes that gap inside the same report.
Writing tools: AITutorMe, grammar checker, summarizer and humanizer
Select a sentence and AITutorMe offers three paraphrased versions you can edit; the summarizer condenses PDFs, DOC and TXT files into short, medium or long summaries; the humanizer rewrites stiff AI text in tones such as natural, conversational or blog. These keep revision in one place, though the word caps on each tool are lower than the checker limits.
Bulk Scan and URL checking
Upload up to 100 DOC, DOCX or PDF files at once (5 MB each) and choose plagiarism, AI detection or both for the batch, with an individual report per file. You can also check a live page by its URL and skip its header, menus and footer. Grading season and content audits stop being one-file-at-a-time chores.
API, MCP and browser extensions
The REST API accepts up to 50,000 words per plagiarism request and 150,000 characters per AI check, returns JSON and exports PDF reports. A hosted MCP connector with OAuth 2.1 lets compatible AI assistants create reports and read your remaining quota, and the Chrome extension checks highlighted text on any page.
Quetext Pros & Cons
Pros
The plagiarism checker is the strongest part of the product. Users on G2 and Capterra say its matching is more trustworthy than free tools like SmallSEOTools or Duplichecker, and that DeepSearch catches rephrased sentences rather than only copy-paste. Reports are easy to read: color-coded highlights, the source in a side panel and a one-click citation fix. Speed is good even on long documents, and the free 1,000-word check needs no account at all. Essential at $8.25/month on yearly billing undercuts most rivals that bundle plagiarism and AI checks, and the API is priced per word with no subscription. Quetext also states that it never sells your work or passes it to third parties. Use it as your default pre-submission check for anything published on the open web.
Cons
Coverage is limited to the open web and Quetext’s own index, so a 0% score does not mean Turnitin, with its private student-paper archive, will agree. AI detection is a secondary feature: independent reviewers report weaker confidence on paraphrased or humanized text and occasional false positives on formal or technical human writing. Word caps replaced the old unlimited plan years ago, and some long-time users still complain about monthly limits and slow support replies. Selling a humanizer next to an AI detector may also look odd to teachers. Language support is broad but not universal, with English plus about sixteen other languages listed. Never treat an AI score as proof; read the flagged sentences and ask for drafts or sources before acting.

Quetext alternatives
Quetext Reviews
An SEO practitioner on Reddit says most plagiarism tools, even paid ones, are easy to game by changing a few words, but Quetext still holds up well enough that they stopped paying for Copyscape.
A G2 reviewer compared it with Duplichecker, SmallSEOTools and Plagiarism Checker X and found Quetext’s results noticeably more promising and trustworthy than those free alternatives.
Capterra reviewers like that DeepSearch flags rephrased sentences, not just exact copies, and that clicking a color-coded match opens its source in the side pane; large documents also scan quickly.
A blogging team on Reddit called the checker great but expensive, complaining about monthly fees plus a page cap and a support request that went unanswered for five days.
A freelance writer on Reddit described a client dispute after an article that scored clean at delivery showed a 52% match a month after publication, a reminder to keep the original dated report.
FAQ
Is Quetext free?
Yes. You can check up to 1,000 words for plagiarism without signing up, and a free account adds AI detection up to 1,000 words plus the summarizer and humanizer up to 2,000 words. Paid plans start at $14.99/month, or $8.25/month billed yearly.
Is Quetext as good as Turnitin?
For web-published sources it is a solid, much cheaper check, but it does not search Turnitin’s private database of student submissions. A low Quetext score therefore does not guarantee a low Turnitin score.
Does Quetext detect ChatGPT and other AI text?
Its AI detector scores text sentence by sentence and is built to flag output from models such as ChatGPT, GPT-5, Claude, Gemini, Llama and Mistral. Accuracy drops on heavily edited or humanized text, so treat the result as a signal rather than proof.
Does Quetext store or sell my documents?
Quetext states that your submitted work is yours and that it never sells it or passes it on to third parties. Payments go through an external gateway, accounts support multi-factor authentication, and reports you create stay in your dashboard until you delete them.
What languages does Quetext support?
The homepage lists 17 languages, including several English variants, French, Spanish, German, Italian, Portuguese, Polish, Romanian, Dutch, Turkish, Vietnamese and Indonesian.
Does Quetext have an API?
Yes. The REST API costs $0.10 per 1,000 words from a prepaid wallet, new accounts get 5,000 free words, and the rate limit is 10 requests per 5 seconds. A hosted MCP connector is also available for AI assistants.
What file types can I upload?
Bulk Scan accepts DOC, DOCX and PDF files up to 5 MB each, and the API also takes TXT files up to 10 MB. You can paste text directly or check a live web page by URL.
Can I cancel or change my plan?
Yes. You can upgrade, downgrade or cancel at any time from the subscription page in your account, and changes apply from the next billing cycle.
