Writers assume that using Quillbot will bypass modern AI detectors. But in most cases, the writing generated by the tool gets flagged. Let's see how Humanize AI Pro compares to Quillbot.
What Makes Quillbot Undetectable to AI Detectors Impossible
Quillbot relies on paraphrasing sentences by substituting synonyms (like switching "use" into "utilize") and transforming text from active to passive voice.
Even though it makes the text appear dissimilar to a plagiarism detector, AI detectors don't look for plagiarism. These tools measure the predictability rate. Quillbot cannot hide the statistical features of machine writing, so GPTZero and Turnitin easily recognize its output as AI-generated.
Why Choosing Humanize AI Pro Makes More Sense
As opposed to Quillbot, Humanize AI Pro was built with AI evasion in mind:
- Statistical Manipulation: The algorithm changes the sentence structure completely to introduce burstiness.
- Preserves Context: It keeps the exact same meaning of your original sentence while preserving the level of professionalism.
- Absolutely Free: There are no limits on the number of words you can process — no caps, no signups.
