What is UnTXT?

Definition: UnTXT is a web-based AI writing detection tool developed by Sataklela OÜ. It analyses text pasted by the user and highlights specific passages that match AI writing patterns, using ten independently-weighted detection modules. Each flagged passage is colour-coded by signal type so users know not just that a passage is flagged, but which kind of AI pattern it matched.

UnTXT is available at untxt.uk as part of the CVaaS ecosystem. It requires no software installation and is accessed through a web browser. Sign-in uses Google OAuth. The first 5,000 words are analysed free on sign-up.

Core Purpose

UnTXT solves a specific problem: when someone reads a piece of writing and suspects it contains AI-generated passages, they need to know which passages and why. A percentage score does not tell you which sentence to rewrite. UnTXT does.

Key Capabilities

10-module detection engine: SPIKE (AI buzzwords), SYNTAX (repetitive structure), FORMAL (hedging language), HUMAN (genuine markers — positive signal), TEMPLATE (boilerplate phrasing), FRONTED (fronted adverbials), FORENSIC (style inconsistency), RHETORIC (AI rhetorical structures), PUFF (inflated/promotional language), FORMULA (challenge-and-future-outlook template)
Two analysis modes: Academic Mode (full 10-module breakdown) and Standard Mode (HIGH RISK / MEDIUM RISK / POSITIVE)
Analysis history: All analyses saved per account with date, word count, score, and credit cost
PDF export: Formatted A4 analysis report for Teacher and Professional roles
CVT credit gifting: Transfer unused credits to another registered user
Role-based interface: Student, Teacher, or Non-academic professional
Multi-currency pricing: 14 currencies supported
Sentence-Scope Editor: Full-sentence replacement suggestions shown in context — accept, modify, or dismiss each rewrite without leaving the analysis view
Invite & Earn: Personal referral link for every user — both referrer and new user receive bonus CVT credits when the invitee completes their first analysis
Confidence Guard: Stricter detection thresholds for Teacher and Professional roles, reducing false positives in review workflows where accuracy is critical
