Hey Product Hunt! I built HumanizeFast because I kept seeing people struggle with AI detection — even when they only used AI as a starting point for their writing.
The tool goes beyond simple synonym swapping. It analyzes the patterns that detectors look for (uniform sentence structure, predictable vocabulary, overly consistent tone) and restructures the text to sound naturally human.
You can try it right now at humanizefast.com — 500 words/day free, no signup. The built-in detector comparison shows exactly how much the AI score drops.
Would love your honest feedback!
