Frequently asked questions

What does Humanizer do?
It rewrites text, often AI-generated, so it reads more like a person wrote it. Quick mode, free in your browser, swaps stock phrases and stiff words for plainer ones, drops filler openers such as "Moreover", adds contractions and varies sentence length. Your numbers and names stay the same.
Will it get my text past AI detectors?
No tool can guarantee that, and AI detectors often get it wrong in both directions. Quick mode changes wording and rhythm, not ideas or structure, so detectors such as GPTZero or Turnitin may still flag the text. The AI pattern score is an estimate from writing patterns, not the result of a specific detector.
How is the AI pattern score calculated?
It looks at patterns common in AI-written text: stock phrases such as "plays a vital role", sentences that are all about the same length, sentences that start with words like "Moreover", words that repeat a lot, and a lack of contractions. It needs at least 40 words.
Does it change my meaning?
Quick mode only replaces phrases and words with plainer ones, drops filler openers, and splits or joins sentences at words like "but" and "and". It does not add or remove ideas. Numbers, names, links, email addresses and quoted text are found automatically and never changed.
What is the difference between the modes?
Light swaps stock phrases and stiff words. Balanced also drops filler openers and adds contractions. Deep also varies sentence length. If the score is still high, Humanizer runs once more at the next level.
Can I change just one sentence?
Yes. Click any sentence in the result to get up to three new wordings, then pick the one you like.
What files can I upload?
Word (.docx), PDF (.pdf), plain text (.txt) and Markdown (.md) files up to 5 MB. Older .doc files need to be saved as .docx first. Scanned PDFs without a text layer cannot be read.
Where does my text go? Is it stored?
In Quick mode your text never leaves your device: the rules run in your browser. Your history is saved only in your own browser, and you can delete it at any time from History.
How many words can I rewrite?
Up to 3,000 words at a time in Quick mode. Split longer documents into parts.
Is it OK to use for school or work?
Check the rules where you study or work. Many places ask you to disclose AI use. Humanizer helps you improve your writing; following those rules is up to you.
