Scanners#

Quadrant IntegrityLens uses a collection of rule-based scanners to detect patterns characteristic of AI-generated text. Each scanner focuses on a specific type of indicator.

Scanners fall into five categories:

Unicode Characters — special characters that AI inserts but students rarely type
German Language — umlaut digraphs and AI vocabulary patterns
Swiss German — Eszett detection for Swiss Standard German
Rhetorical Patterns — overused AI writing patterns in German
Structural Patterns — formatting artifacts typical of AI output

Confidence levels#

Each finding has a confidence level:

Level	Meaning
High	Strong indicator of AI-generated text
Medium	Likely AI-generated, but could occur naturally
Low	Weak indicator — consider alongside other findings

A single Low-confidence finding means little on its own. Multiple findings across different scanners paint a clearer picture.

Disabling scanners#

Any scanner can be disabled with the --disable flag using either the scanner ID (disables the entire scanner) or a rule ID (filters individual findings):

integritylens --disable swiss-german document.pdf
integritylens --disable eszett document.pdf
