AI text humanizer

How does humanization work?

Our humanizer uses Claude (Haiku model) with a highly specific prompt: vary sentence lengths, remove a list of 80+ stock LLM phrases, avoid repeated openers, add natural contractions. Goal: break the statistical patterns detectors (OriginalityAI, GPTZero, Copyleaks) use.

Once rewritten, we immediately re-run our own heuristic detector (in-browser) on the result to show you the human score before/after. Measurable proof the transformation worked.

When to use the humanizer

• You generated a draft with ChatGPT/Claude and want to polish before publishing.
• You publish on platforms penalizing raw AI content (Medium, certain forums, educational platforms).
• You freelance for a client requiring "human-written" content.
• You want to preserve facts from an AI text while making it more engaging to read.

Which intensity to choose?

3 levels depending on your goal:

• Light — fixes only obvious AI phrases ("it is crucial", "moreover"). Preserves 90% of original. Ideal if you just want the "tells" gone.
• Medium — rewrites paragraphs varying lengths and structures while preserving meaning. Default choice, best quality/preservation tradeoff.
• Aggressive — deep rewrite. Restructures paragraphs, adds casual contractions, breaks rhythm radically. Use when text is really too "GPT".

Limits to know

No tool guarantees 100% pass on commercial detectors. Detection models (OriginalityAI, GPTZero) evolve constantly. Humanization can take a text from 30% to 75% "human", but rarely 95%+ without human review.

Humanization preserves meaning but may slightly alter tone. For high-stakes texts (legal, medical, journalistic), human review is essential. Treat this tool as an advanced draft, not a final publication.
