In-Depth Feature Analysis

Detection Technology Comparison

StealthWriter employs a hybrid approach with three scoring layers—LLM analysis, statistical features, and perplexity metrics—producing more nuanced results. Key differences in practice:

Multi-model detection: StealthWriter identifies content from GPT-4, Claude, Gemini, and more, while Originality.ai has broader coverage of older models but sometimes struggles with newer ones
Confidence scoring: StealthWriter provides segment-level analysis showing which specific paragraphs are likely AI-generated, rather than just an overall score
False positive rates: In our testing, StealthWriter showed a 1.2% false positive rate compared to Origonality.ai approximately 4%

Pricing Model Differences

This is a critical difference for budget-conscious users. Originality.ai uses a credit-based system at $14.95/month for a limited number of scans. Once credits are exhausted, you must purchase more or wait. StealthWriter offers a free tier plus an unlimited Pro plan at $9.99/month—no credit counting, no surprise charges.

Use Case Fit

Originality.ai excels in the content marketing niche with features like site-wide scanning and a Chrome extension for quick checks. StealthWriter is more versatile—its integrated Writing Assistant, AI Humanizer, and academic research tools make it suitable for marketers, educators, students, and businesses alike.
