Keep the input language automatically
Certentis detects the dominant input language and rewrites the text in that same language—without requiring you to choose a target language.
Humanizer
Humanize AI text naturally with Humanizer
Certentis Humanizer rewrites existing AI drafts and original texts in the automatically detected input language. It refines sentence structure, rhythm, and word choice, while letting you compare the result with the original.
For work, editorial tasks, study, and everyday writing—with careful attention to academic terminology and quotations. This is not a translation, and no AI detector score is guaranteed.

05Three simple steps
From draft to controlled rewrite
- 01
Add your text
Paste an existing draft. Certentis detects the language and analyzes the source text.
- 02
Rewrite naturally
Humanizer varies sentence structure and wording while preserving key statements and protected elements as closely as possible.
- 03
Compare both versions
Review differences, analysis metrics, and sensitive information before using the rewritten version. You remain responsible for the final content review.
06Natural rewriting
Humanize AI text while keeping the content in view
A good Humanizer makes existing wording smoother and more natural while staying aligned with the original content, terminology, and sources.
Protect important content selectively
Technical terms, names, numbers, and quotations are treated as elements that require special protection during rewriting.
Review every change clearly
The original and rewritten result remain available side by side. Review nuances, key details, and intended meaning before accepting the changes.
07Fair comparison
Seven Humanizers. The same source texts.
This table reports a dated internal comparison, not a universal ranking. The combination of quality, semantic fidelity, and formal safety matters more than one detector score.
