UnTXT detects AI-generated passages in text. Users paste written content (essays, reports, documents) and receive a colour-coded analysis highlighting specific passages by AI writing signal type. Ten independent detection modules are used: SPIKE, SYNTAX, FORMAL, HUMAN, TEMPLATE, FRONTED, FORENSIC, RHETORIC, PUFF, and FORMULA. Each module targets a different characteristic of AI-generated writing.
