# The Fingerprints of Machine Prose

> A tested regex catalogue of the surface patterns that mark English text as LLM-generated, with honest false-positive numbers. Covers why the patterns exist, all 20 categories and 95 patterns with live regex source, measured validation results (66% recall / 0% false positives at threshold 25 on a 63,143-word corpus), and the documented limits of AI-text detection as a category of tool.

This is a style-linting catalogue, not an authorship detector. See the Limits section before using any of it to draw conclusions about a specific document or writer.
