AI Writing Glossary
Clear definitions for the terminology behind AI detection, humanization, and the tools that screen your writing — built for students, professionals, and content teams.
AI Detection
The process of identifying whether text was written by a human or generated by an artificial intelligence language model.
AI Humanizer
A tool that rewrites AI-generated text to reduce detection scores and improve natural, human-like readability.
Burstiness
The variation in sentence length and complexity throughout a text — human writing is bursty; AI writing tends toward uniform rhythm.
GPTZero
A widely used AI detection tool that analyzes text for perplexity and burstiness to estimate AI authorship probability.
Originality.ai
An AI detection and plagiarism platform popular with SEO teams, publishers, and content agencies for auditing written content.
Paraphrasing Tool
A writing tool that rewrites text by changing words and sentence structure — distinct from a dedicated AI humanizer.
Perplexity Score
A statistical measure of how predictable each word in a text is — low perplexity is a primary signal that text may be AI-generated.
Turnitin
An academic integrity platform used by universities worldwide, now including AI writing detection alongside traditional plagiarism checks.
