Does Grammarly Have an AI Humanizer?

The Core Misconception: Does Grammarly Offer an AI Humanizer?

I consistently encounter this exact question in university writing forums and digital marketing subreddits: "Can I simply rely on Grammarly Premium to passively humanize my ChatGPT essay so I avoid Turnitin flags?" The objective answer to this is a very loud, resounding NO.

In fact, utilizing standard Grammarly functionality to heavily edit your synthetic draft will almost consistently make your text look significantly more like AI to a strict algorithmic detector. It actively works against the core principles of text humanization.

How Grammarly Actually Operates Under the Hood

To understand why this fails, you must understand Grammarly's foundational intent. Grammarly's core corporate mission is to comprehensively make your writing "Perfect." It aggressively removes natural wordiness, strictly standardizes your grammar formatting, aggressively regulates your comma usage, and constantly suggests "better," more professional vocabulary synonyms.

The catastrophic problem here is that absolute "Perfection" is exactly the primary mathematical fingerprint that institutional AI detectors are programmed to aggressively look for. Large Language Models are heavily trained on perfect, standardized data. Genuine, biological humans, however, are inherently messy writers. We frequently utilize slightly unconventional sentence structures, wander off mid-thought, and feature a distinct "jitter" or chaotic rhythm in our organic writing pacing.

When you run a document through Grammarly, it actively removes that natural human algorithmic jitter. It algorithmically smooths your text into extreme perfection, which moves your document safely into the dreaded "Highly Likely AI" category for strict tools like Originality.ai or Turnitin.

The Correct Workflow You Should Implement Instead

If you are currently holding an AI-generated draft, you must intentionally use a tool explicitly designed for undetectability, not standard grammatical correction. Perfection is your enemy formatting here.

1. Humanize the Document First: Aggressively run your raw text through a dedicated, adversarial processor like Humanize AI Pro. This highly specialized tool will actively break the perfect generative patterns. It will strategically inject the natural, chaotic "burstiness" and heightened numerical perplexity that correctly signifies genuine human writing.
2. Correct the Formatting Last: Once the advanced humanizer has effectively scrubbed the mathematical machine fingerprint and rendered your text proudly undetectable, then you can run a highly targeted, basic spellcheck. But proceed with extreme caution—if you allow Grammarly's generative assistant to aggressively "rewrite" too many full paragraphs for clarity, it will accidentally re-introduce the exact sterile AI fingerprint that you just spent valuable time permanently removing.

Ultimately, use Grammarly exclusively for standard corporate emails or social media management where looking incredibly polite and flawlessly professional is the only goal. But if you are actively attempting to bypass an institutional AI detector, you absolutely need a tool that is highly comfortable injecting a carefully calculated bit of human imperfection.
