Frequently Asked Questions
Everything you need to know about AI writing patterns, detection, and conversational social copy.
Q.Why does AI-generated text hurt engagement on LinkedIn and Instagram?
Social media algorithms prioritize comments and dwell time. When readers spot telltale ChatGPT phrases like "delve into," "rich tapestry," or unspaced em-dashes ("—"), they subconsciously tune out as generic spam. Authentic, conversational human copy generates up to 4x higher comment depth.
Q.What are invisible AI watermarks and zero-width characters?
Large language models and AI scrapers frequently output invisible Unicode characters like Zero-Width Space (\u200B) or Byte Order Marks (\uFEFF). AI detection models and platform spam filters look for these hidden byte patterns to flag computer-generated text.
Q.Does this tool make any external AI API calls or store my drafts?
Zero API calls. The humanizer runs 100% in your browser using a custom client-side linguistic regex dictionary. Your sensitive business announcements and client drafts never leave your device.
Q.How is the Human Authenticity Score calculated?
The score (0–100%) analyzes your text against three critical dimensions: hidden zero-width watermarks (heavy penalty), overused AI buzzword density per word, and robotic punctuation markers (em-dash frequency and repetitive colon lists).
Q.What does 1-Click Auto-Clean do?
It strips all hidden zero-width watermarks, converts overused AI clichés to their most natural conversational human synonyms, normalizes em-dashes into clean hyphens, and removes emoji clusters in a single millisecond.
