Why Choose AI Detector

Engineered for precision and clarity.

Built to provide clear, measurable analysis using transparent client-side algorithms.

01Burstiness & Length Variance

Measures standard deviation in sentence lengths to distinguish human rhythmic variation from flat, uniform machine outputs.

02350+ Machine Token Scanner

Flags telltale AI buzzwords and overused corporate phrases like 'delve deeper', 'rich tapestry', 'pivotal role', and 'testament to'.

03Rhetorical Triad & Antithesis Matcher

Detects formulaic parallel triads ('X, Y, and Z') and balanced 'not only... but also' constructs characteristic of GPT models.

04Lexical Diversity (TTR) Index

Calculates Type-Token Ratio to identify vocabulary repetition and repetitive connective phrasing.

05Sentence-by-Sentence Map

Visual cards color-coding each sentence from 5% to 99% AI likelihood with specific flagged markers.

06Client-Side Engine

Zero API calls. Your text never leaves your browser, ensuring complete confidentiality for proprietary drafts.

Step-by-step workflow

How it works in 4 simple steps

From raw draft to polished, verified copy in seconds.

01Paste or Type Text

Enter any article, essay, or email draft into the editor, or load curated sample presets.

02Statistical & Token Analysis

The engine parses text tokens, computes sentence variance equations, and scans against our 350+ AI lexicon.

03Review Sentence Map

Inspect the composite score and examine individual sentences flagged for flat machine length, triads, or buzzwords.

04Refine or Humanize

Use the breakdown to rewrite machine-like passages or switch to the Deep Humanizer.

Common questions

Frequently Asked Questions

Straight answers about accuracy, privacy, technology, and limits.

How does the in-browser detector score AI content without calling a server?

Large Language Models (LLMs) exhibit consistent statistical signatures: uniform sentence length (flat 14–19 word variance), lower Type-Token lexical diversity, characteristic parallel triads, and distinct high-frequency buzzwords ('delve', 'tapestry', 'testament'). Our client-side engine executes exact mathematical variance equations and regex token scanning locally in your browser in milliseconds.
