Free AI Writing Detector and Burstiness Analyzer
An AI writing detector analyzes statistical patterns in text cadence, vocabulary uniformity, and sentence length variance. Our free detector calculates a live probability score directly in your browser without transmitting your drafts to external servers.
100% In-Browser Privacy Protection
All text heuristics and canvas pixel inpainting run locally in your web browser. Zero server uploads.
AI Detector Analysis Case Study
See how the tool analyzes unedited AI slop and transforms it into natural human writing.
"Certainly! Here is an in-depth analysis. In today's fast-paced digital landscape, it is important to remember that navigating the intricate tapestry of modern technology serves as a testament to human potential. Furthermore, by delving into the multifaceted realm of automated systems, businesses can seamlessly foster growth, elevate standards, and unlock unprecedented possibilities. In conclusion, only time will tell how this double-edged sword will shape our future."
"Modern software tools automate repetitive paperwork. You can finish reports in minutes instead of hours. Teams that adopt local tools save time, reduce human errors, and protect client privacy. Try running a pilot with one department this week."
Key Changes Applied in This Example:
- Flagged 7 machine buzzwords: delve, tapestry, testament, realm, foster, elevate, unlock.
- Flagged 2 generic AI openers: "In today's fast-paced digital landscape", "Certainly! Here is".
- Detected flat 18-word sentence length cadence.
How to Identify AI-Generated Text Patterns
- Sentence Length Uniformity: Large language models generate uniform sentence lengths around 14 to 18 words, whereas human writers mix short punchy sentences with longer explanations.
- Overused Machine Hallmarks: AI text contains high concentrations of words like delve, tapestry, testament, beacon, pivotal, and furthermore.
- Low Lexical Diversity: Machine algorithms reuse the same transition phrases repeatedly across paragraphs.
Why Use Free AI Writing Detector and Burstiness Analyzer? Common Problems Solved
Here is exactly why creators, developers, and businesses use this tool to overcome real-world workflow bottlenecks.
Government portals, job application boards (Workday, Taleo), and university admission systems frequently reject unsupported files due to strict backend validation rules.
Convert your file to universal standard format in seconds so your upload passes automated portal checks with zero formatting errors.
Gmail, Outlook, and Discord enforce strict 25MB attachment limits, blocking heavy uncompressed documents, raw images, and audio files from sending.
Transform heavy payloads into compressed, web-optimized formats that easily fit under email attachment caps while preserving visual fidelity.
Unoptimized formats degrade website Largest Contentful Paint (LCP) scores, hurting Google search rankings and increasing mobile bounce rates.
Produce next-gen, browser-friendly assets that load instantly across all desktop and mobile network connections.
Opening fixed desktop layouts on mobile phones forces readers into annoying horizontal scrolling and tiny unreadable text.
Deliver responsive assets that naturally adjust to any smartphone or tablet screen size without manual zooming.

Frequently Asked Questions
How does this AI detector work without server APIs?
The detector runs client-side statistical linguistics. It calculates standard deviation across sentence lengths (burstiness), vocabulary distribution (Type-Token Ratio), and flags overused machine phrases directly in your browser memory.
Are my private essays or drafts stored on your server?
No. All text is analyzed locally in your web browser. Nothing is sent to any remote server or stored in any database.
