I put the Humanize AI to the test with three AI-generated text samples.
In this post, I’ll test and give an overall review of the tool, and show the results.
In my reviews, I emphasize the ease of use, and will only test free tools, or tools with Free trials.

How to Use It
Using Humanize AI is very easy. On their website’s homepage, you can find the Humanizer.
Just paste your text here directly and click on “Humanize AI”. The Free version puts you in the queue; for me it took roughly 3 minutes for each scan.
My Results
I asked ChatGPT to generate three different text samples on random topics. Then, I humanized the texts using Humanize AI and ran a separate AI detection scan on Undetectable AI to see their AI scores after humanizing.
Text sample number 1:
Words highlighted in green are changed from the original text.
This is the result of the AI Detection scan. The text received 99 % probability of being AI-generated AFTER the humanizing.
Text number 2:
Text number 3:
Not very convincing. All of the text samples got an AI score of almost 90 % after using the humanizer.
Upon signing up, a new feature is unlocked. The “Ultra run” makes your text “Undetectable by all AI Detectors”. I decided to give it a try. I ran the scan again on text number 3 and put it on the AI Detector.
It slightly improved the results, but definitely not to 0 % AI as promised.
Pros
- Easy to use, can use without signing up
- Has other AI-content features
- Chrome and Google doc add-ons are convenient
Cons
- Limited credits with the free trial
- Free version doesn’t highlight which parts of the texts are AI-like
Pricing
Here are the pricing plans of Humanize AI. My test was based on the Free version, they offer a refund if your text gets flagged as AI after purchasing a paid plan.
To Take Home
Humanize AI is a tool solely focusing on humanizing AI-generated texts. It also has an AI Detector feature. The tool can be used without a subscription but it comes with a word limit of 300 words.
I tested the Free version and the results weren’t very convincing. The tool failed to humanize the AI-generated text samples I provided. Only after testing the “Ultra run” feature available after signing in, the score improved to 60 %, which is still not acceptable.
The paid plans come with a refund policy. If your text still gets flagged as AI after humanizing, you are eligible for a refund.
My test text samples
Here are the text samples I used. The samples are generated 100 % by ChatGPT. The samples are different topics and lengths, varying from 150 words up to 500 words.
Text sample 1 — 150 Words
Houseplants do more than decorate our homes; they quietly transform the air we breathe and the way we feel. A touch of green can soften even the most sterile apartment, making it feel alive and personal. Caring for plants teaches patience — you can’t rush a seed to sprout or a leaf to unfurl. Each morning, a small routine of watering or pruning becomes a mindful pause in the day. The scent of soil, the sight of new growth, and even the occasional wilted leaf remind us that everything thrives through attention and consistency. Beyond aesthetics, studies show that plants reduce stress and improve concentration, making them tiny guardians of both mood and productivity. In a world full of screens and noise, a simple pothos on a windowsill offers a quiet, grounding reminder of nature’s calm persistence.

Coffee is more than a beverage — it’s a ritual, a global language spoken in mugs and espresso cups. From the bustling cafés of Rome to the quiet drip brewers of Japan, coffee culture reflects both tradition and innovation. Each region adds its own personality: Italians linger over a quick espresso, Scandinavians sip black filter coffee, and Australians have perfected the smooth, creamy flat white.
What makes coffee special isn’t just caffeine; it’s connection. We meet friends “for coffee,” brainstorm over it, and pause mid-morning to refocus. The familiar aroma signals comfort and productivity all at once. Even in solitude, brewing coffee feels communal — millions of people perform the same act every day, in different corners of the world.
Beyond its social role, coffee is a science of flavor. Roast profiles, grind size, and water temperature determine whether a cup tastes rich and nutty or sharp and citrusy. Specialty roasters and baristas treat it as an art form, crafting drinks that highlight subtle notes like chocolate, berries, or flowers. The modern coffee movement has revived appreciation for the farmers and regions behind each bean, encouraging sustainability and fair trade.
Ultimately, coffee unites people not just through shared taste, but through shared time — a few quiet minutes in an otherwise restless day.

IFor centuries, humans have looked up at the night sky in wonder. Before city lights and technology, the stars were our calendar, our map, and our mythology. Even today, when satellites and telescopes have revealed much about the universe, the act of stargazing still feels deeply human — a bridge between curiosity and peace.
The beauty of the night sky lies in both its mystery and familiarity. We recognize constellations that our ancestors once named, from Orion’s Belt to the Big Dipper. These patterns remind us that across cultures and millennia, people have shared the same view above. It’s humbling to realize that the light we see from some stars began traveling toward us millions of years ago. In every small point of light lies the story of time itself.
Modern astronomy has only deepened that wonder. With even a small telescope, anyone can see Jupiter’s moons, Saturn’s rings, or the soft glow of distant galaxies. Yet, what moves us most isn’t the data or the science — it’s the feeling. Standing under a clear night sky, we sense both our insignificance and our connection to everything.
Stargazing also offers rare quiet in a busy world. When you turn off your phone and let your eyes adjust to the dark, your thoughts begin to slow. You notice the rhythm of your breathing, the coolness of the air, the vastness of space stretching above you. It’s meditation through observation.
Whether you’re in a remote field or leaning over a balcony in the city, looking at the stars is a reminder of perspective. Our daily worries — emails, deadlines, arguments — shrink beneath the cosmic scale. The stars remind us that time is immense, yet every moment we experience under them is uniquely ours.
