AI That Writes Like a Human

    Loosens mechanical cadence so the draft reads like a person wrote it.

  • Keep the quotation. Rewrite the filler around it so the page still sounds like you.

    Contains no plagiarism

    We start from the text you paste. Quotes, URLs and numbers stay visible.

  • 120+ languages supported

    A French draft stays French.

  • Become undetectable.

    Humanize, then check

    Rewrite the draft, then scan the same text or document.

Before vs After

AI-generated text can look human at first glance. IA Checker reveals the repeated wording, rhythm, and sentence-level signals hidden underneath.

Look closer at every sentence.

Good to know

Before you keep the rewrite.

What changes, what gets checked and what no humanizer can promise for you.

What does the AI Humanizer actually change?

It can reshape openings, sentence order, rhythm, transitions, contractions and register while aiming to preserve the source language, meaning, facts, quotations and intent. The result includes comparison and review tools so you can verify that aim.

Does humanized text become undetectable?

No. No rewrite can guarantee a detector outcome or prove human authorship. IA Checker’s Humanizer is an editing tool, not a certification or a promise to bypass detection systems.

How does it protect facts and quotations?

Detected URLs, emails, dates, numbers and direct quotations receive exact-span checks. The pipeline also reviews meaning, facts, language and named entities semantically. Those checks reduce risk but do not replace your own factual review.

Will I always receive two candidates?

Not always. A run can return one plain result or, when the active backend supports it, up to two ranked candidates. Text, Diff and Why views are available on ranked-candidate runs.

What can I control in Advanced mode?

You can choose Faster or More human, add a custom instruction, mix up to two of six voice patches and adjust voice variation. Advanced can be tried without an account; shared daily model limits apply.

What are the input and privacy limits?

The live editor requires at least 12 words and accepts up to 20,000 characters. Document upload follows plan and file limits. Text is sent through IA Checker’s server and model provider for processing rather than staying only in your browser.

Keep the meaning. Take ownership of the voice.

Advanced mode can be tried without an account. Shared daily limits apply, and the final editorial decision stays with you.
