Quetext: cost, fit and limits
Quetext is a plagiarism and AI content checker made by Quetext Software LLC that offers a DeepSearch plagiarism scan, an AI Content Detector, bulk uploads, browser extensions and an MCP server for individuals, students and teams on word-based monthly plans.
What to know first
Quetext starts free: the plagiarism checker and the AI Content Detector each take up to 1,000 words, with an AI summarizer, a humanizer and a citation generator alongside. Essential from $14.99 a month raises the allowance to 100k words and adds API access, and Professional from $29.98 doubles it. The privacy policy makes user content eligible for AI training by default, and opting out means emailing the company.

Who Quetext is best for
Students on a budget
The free plan covers 1,000 words in both checkers, enough to test a paragraph or a short assignment before paying for a monthly plan.
Solo writers and bloggers
Essential adds 100k words a month, 20 bulk files and extensions for Chrome, Firefox and Edge, so a blogger can check drafts while writing.
Small teams
Professional offers 200k words, 100 bulk files and a remarks tool, which lets a reviewer leave notes on a document for the author.
Users of AI assistants
The Quetext MCP lets an AI assistant run checks, which helps workflows where a model drafts and a checker verifies the output.

What Quetext does
- DeepSearch scanning
- The plagiarism checker is branded DeepSearch and runs against a word allowance that depends on the plan, so quota planning matters more than per-document pricing.
- AI Content Detector
- The detector is part of the same allowance as plagiarism checks and, per the FAQ, also works in 25 languages, which gives non-English users some coverage, though the pages read do not list those languages.
- Bulk uploads
- Essential allows 20 files and Professional 100 in one batch, which suits a teacher or editor who collects a whole stack of submissions and wants to check them in one batch.
- Extensions and add-on
- Browser extensions for Chrome, Firefox and Edge plus a Google Docs add-on bring checks into the places where students and writers already draft text, with no separate upload step in most cases.
- ColorGrade and remarks
- ColorGrade gives students feedback on their results, and the remarks tool on Professional lets a reviewer comment on a document inside the account, which helps a teacher return notes to a student.
- MCP access
- A Quetext MCP lets AI assistants call the checker directly, so a model-driven workflow can verify its own output without a manual copy-and-paste step between two windows.
How Quetext handles your data
The privacy policy says user content and service usage data may be included in AI training, evaluation and quality assurance by default. Users who want out must email privacy@quetext.com with the subject AI Opt-Out. Personal data is kept only as long as needed, but aggregated and derived data may be retained indefinitely. Transfers may include the United States and the data location is not stated. No certification appears on the pages read, so the vendor's policy was not checked for any.
Where Quetext falls short in practice
- Free tier is tiny. 1,000 words per checker covers an abstract or one page of an essay, so a thesis chapter needs a paid plan before it can be scanned in full.
- Opt-out by email. Excluding content from AI training needs an email request, with no settings toggle named on the pages read, which slows onboarding when the material is confidential or unpublished.
- Word caps on every plan. Both paid plans meter plagiarism and AI checks in one monthly pool, so a team that scans long reports twice can exhaust 100k words quickly.

Quetext: common questions
How many words can Quetext check for free?
The free plan allows up to 1,000 words in the plagiarism checker and 1,000 words in the AI Content Detector, plus up to 2,000 words in the summarizer and 500 in the humanizer. That fits a short test, but not a full thesis chapter.
What does Quetext Essential include?
Essential starts at $14.99 a month and includes 100k words a month for plagiarism and AI detection, 20 bulk files, API access, an AI humanizer and summarizer, and 25k words of AITutorMe. The yearly toggle shows a 40% badge, so confirm the final yearly price at checkout.
Does Quetext use my documents for AI training?
By default, user content and usage data may be included in AI training, evaluation and quality assurance. You can opt out by emailing privacy@quetext.com with the subject AI Opt-Out. Do that before checking unpublished manuscripts, client work or student submissions.
Does Quetext offer an API?
Yes. API access is listed on both Essential and Professional. The pages read do not describe rate limits or pricing beyond the plan allowance, so check the developer documentation or ask support if you plan to wire it into a content system.
Which languages does the AI detector support?
The vendor's FAQ says the AI Content Detector works in 25 languages. The pages read did not list them or give accuracy per language. Test a sample in the language you actually need on the free plan before you pay for anything.
