While many writers use Grammarly for text polishing, they are mistaken. Using it to improve text will raise your risk of being flagged by an AI detector. Here is how and why it works.
Why Grammarly Raises Your AI Detection Score?
AI detectors rely on the assessment of perplexity (randomness of word choice). Grammarly's main algorithms are designed to accomplish the exact opposite — it simplifies the text to improve its readability.
Replacing unusual and complex phrasing with standard and concise language options increases text predictability significantly. For GPTZero or Turnitin, such a text seems 100% machine-written and gets a high AI score.
How to Safely Combine Grammarly with Humanize AI Pro
If you want to write clean professional text that cannot be detected by an AI:
- Draft with ChatGPT/Claude: Use one of the best AI tools for generating initial ideas and arguments;
- Humanize your text: Paste your draft into an AI humanizer to restructure the text and lower its AI signature;
- Proofread with Grammarly: You can use Grammarly only for catching spelling and punctuation mistakes but not for structural changes.
