Frequently Asked Questions
Everything you need to know about AI text detection, burstiness, and false positives.
01. How does the UnmarkPro AI Content Detector work? ↓
UnmarkPro uses a multi-layered client-side stylometry engine. It analyzes sentence burstiness (variance in sentence lengths), lexical diversity (type-token ratio), and cross-references against a proprietary catalog of high-frequency AI cadence phrases commonly produced by ChatGPT, Claude, and Gemini. Processing executes 100% in your local browser sandbox.
02. How is UnmarkPro different from ZeroGPT and Turnitin? ↓
ZeroGPT and Turnitin upload your full writing to remote cloud servers, storing copies in corporate databases and training models on your intellectual property. UnmarkPro executes 100% locally in your browser memory: zero words leave your device, zero logs are kept, and you get an immediate 1-click button to humanize flagged phrases.
03. Can this detector identify ChatGPT, Claude, and Gemini text? ↓
Yes. Our engine is calibrated for GPT-4o, GPT-4, Claude 3.5 Sonnet, Google Gemini 1.5, DeepSeek, and LLaMA models. It flags formulaic transitions, uniform sentence structures, and predictable vocabulary distributions characteristic of large language models.
04. What should I do if my human-written text is flagged as AI? ↓
False positives occur when human writing relies heavily on repetitive business clichés (e.g., 'in today's fast-paced world', 'delve into', 'pivotal role') or maintains perfectly uniform sentence lengths. Use our integrated AI Humanizer button to increase burstiness and vary sentence cadence so detectors recognize your work as human.
