Quillbot’s AI Humanizer claims to turn robotic text into natural writing. But does it really sound human? I tested it and compared it to other tools. Here’s what I found.
What Is Quillbot AI Humanizer?
Quillbot is a popular writing tool that helps users rewrite, summarize, and check grammar. The AI Humanizer is one of its newest features.
It promises to make AI-generated text sound more natural, like something written by a real person.
How Does Quillbot AI Humanizer Work?
The Humanizer uses AI models trained on large amounts of text. When you paste your text, the tool rephrases sentences, changes tone, and adjusts word choice to make the writing sound more natural.
Here’s a quick breakdown of how it works:
- Analyzes sentence flow – It looks for robotic phrases or awkward wording.
- Rewrites contextually – It swaps out words while keeping the meaning.
- Adjusts tone – It can make text sound formal, casual, or neutral.
- Keeps readability high – It avoids overly complex words.
In a few seconds, you get text that sounds smoother and more like something a human would write.
Features of Quillbot AI Humanizer
1. Multiple Modes
You can choose from different modes like “Simple,” “Formal,” or “Creative.” Each one changes how the tool rewrites your content. “Simple” is best for clear writing, while “Creative” gives more variety.
2. Built-In Grammar Checker
Quillbot doesn’t just humanize text—it also fixes grammar, punctuation, and spelling issues automatically.
3. Paraphrasing Strength Levels
You can set how much you want the tool to change your text. “Low” keeps your sentences close to the original, while “High” completely rewrites them.
4. Integration With Other Tools
Quillbot works well with Google Docs, Microsoft Word, and Chrome. You can humanize your text directly without switching between apps.
5. Free and Premium Versions
The free plan allows a few uses per day, while the premium plan removes limits and gives access to all modes and advanced rewriting features.
My Testing Process
To see how well Quillbot’s AI Humanizer works, I used text from ChatGPT and pasted it into Quillbot. Then, I compared the results with the original.
Here’s what I found:
- The output was smoother and easier to read.
- It replaced common AI phrases like “In conclusion” or “Overall” with more natural endings.
- It changed sentence order in a smart way, making the text flow better.
- However, it sometimes used words that sounded too simple or repeated phrases.
When I ran the text through an AI detector, the results were mixed. Some detectors said it was human-written, but others still caught parts of it as AI-generated.
So, while Quillbot can reduce the “AI feel,” it doesn’t completely hide it.
Pros of Quillbot AI Humanizer
✅ Easy to use — just paste and click
✅ Polishes grammar and tone
✅ Improves readability
✅ Works with many writing tools

Cons of Quillbot AI Humanizer
❌ Doesn’t always pass AI detectors
❌ Sometimes over-simplifies writing

❌ Limited use in free version
Who Should Use Quillbot AI Humanizer?
- Students who want to rewrite essays in their own voice.
- Bloggers who use AI tools but want a natural touch.
- Content creators who post online and need text that sounds human.
- Marketers who repurpose AI-written posts for social media.
If you fall into one of these groups, Quillbot’s AI Humanizer can save you time and make your writing sound smoother.
How Accurate Is It?
Accuracy depends on the content. If the input is already well-written, Quillbot does a great job polishing it. But if the original text is very robotic, it may still leave traces of AI style.
I found that it works best for general writing like blog posts, summaries, or essays. For technical or creative writing, it sometimes loses the natural rhythm.
Comparison With Other AI Humanizers
There are many tools today that claim to “humanize” AI text. I tested Quillbot alongside others like Undetectable AI, Humanizey, and AItoHuman.
Here’s how Quillbot stands out:
- It focuses more on readability and tone than fooling detectors.
- Its grammar checker is more reliable than most.
- However, it’s not as strong at passing AI detection as some newer tools.
If your main goal is to make writing sound smoother and more readable, Quillbot is solid. But if you want text that fully passes AI detection, there are stronger options.
Why AItoHuman AI Is Better Than Quillbot AI Humanizer?
After comparing many tools, AI to Human performs better when it comes to making AI text completely undetectable.
Here’s why:
- Smarter rewriting – It understands sentence context better and rewrites with real human rhythm.
- Better detection scores – Most AI detectors label AItoHuman’s results as 100% human-written.
- Preserves meaning – It keeps your message clear while removing robotic patterns.
- More natural tone – The output sounds like how people actually talk and write online.
So while Quillbot’s Humanizer is great for light polishing, AItoHuman AI is the better choice if you need text that looks 100% authentic.
Final Verdict
Quillbot AI Humanizer is useful for improving grammar, tone, and readability. It can make AI writing smoother but doesn’t always fool detectors.
For people who just want cleaner writing, it’s a great choice. For those who need truly human-like text, AItoHuman AI does it better.
