UnTXT detects AI-generated passages in text. Paste an essay, report, or submission and it highlights phrases that show signs of AI authorship using 10 independent detection modules: SPIKE, SYNTAX, FORMAL, HUMAN, TEMPLATE, FRONTED, FORENSIC, RHETORIC, PUFF, and FORMULA.

Is UnTXT free to use?

Yes. The first 5,000 words are analysed free on sign-up with no payment information required. Paid credit bundles are available for larger volumes.

How is UnTXT different from other AI detectors?

UnTXT shows which specific passages are flagged and categorises each by signal type (ten named modules), rather than returning only an overall score. It also includes a PDF export for teachers and annual (non-monthly) credit expiry.

Does UnTXT work for professional documents, not just student essays?

Yes. UnTXT has a Non-academic professional role that adapts the interface for reviewing reports, business documents, and other professional content.

Can I download an AI analysis report as a PDF?

Yes. Teacher and Professional role users can download a formatted A4 PDF analysis report from any completed analysis.

What is the CVT credit system?

CVT (Contextual Value Token) is the unit used to measure analysis. 1 CVT covers approximately 75 words. Credits are purchased as one-time bundles, not as a monthly subscription. Purchased credits are valid for 365 days.

Who is UnTXT made by?

UnTXT is a product of Sataklela OÜ and is part of the CVaaS ecosystem, available at untxt.uk.
