- The free trial is a single 300-word humanization
- Its detector score comes from its own model; other detectors may disagree
What ESL Humanizer does differently
- ESL Humanizer is for English you wrote yourself — the fix is for second-language phrasing.
- Every rewrite shows a word-by-word diff and a meaning score.
- We never claim a rewrite will pass a detector; the detection check is an estimate.

A note on AI detectors
No tool can guarantee how an AI detector will score your text. In a peer-reviewed Stanford study, seven detectors labeled 61% of human-written TOEFL essays as AI-generated on average, and independent tests have found detectors disagree with one another. Natural English you wrote — plus drafts that show your process — is the most reliable protection. Read more about why detectors flag ESL writing.
