They keep sending spam emails even after I unsubscribed.
The writing came out stiff, unnatural, and robotic. Not human at all.
Waste of time, it doesn’t work. All it does is change the words and sometimes sentences doesn’t even make sense. Good luck with customer service, they are very rude in their responses.

You normally spend more time trying to fix the nonsense created by this "humanizer." It might work for short paragraphs. I typically work with about 200 words at a time. The outcome is useless, and I end up having to rewrite it by hand. Yes, it will pass AI detection... because it makes no freaking sense. I also had issues twice with the word count/plan in the first month.
I've been using Grubby.ai for a couple of months now. Was satisfied with it even though it occasionally changed the theme of humanised text. HOWEVER, what has made me rate it 3 stars is that the site is not been working in South Asia for over 2 months now. I can't even reach out to Customer Support as the message fails to deliver to CS from the site's Customer Support menu. It is June 2025 as of writing this review. Every time I try to sign in, I get the Forbidden Error 403 message. I can't access the site WITHOUT using a VPN, which is an unnecessary hassle.
terrible software. fails to generate the humanised text and I have tried multiple times to contact help and it fails
It is mentioned that the service supports 30 languages, but when I try to humanize Ukrainian text, all I get is a translation to English. That is not at all what is advertised. Also it is literally impossible to contact them. When I try to send a message by clicking the "help" button, I always get an error and nothing is sent. That all seems like a scam to me.
I tried this tool for my thesis writing, but it does not work as advertised. Don't fall into the trap. I would not recommend anyone waste their money and energy on Grubby AI. I purchased a monthly subscription, and after generating the first few pieces of content, I realized it was useless to put any further effort into it. Once you make a payment, forget about getting a refund. I used around 1,000–1,500 words, and I still have about 28,000 words left in my subscription, which are completely useless. The output sentences are completely distorted and totally change the intended meaning to something new. Furthermore, the content is still flagged as AI-generated by AI detectors, even after using both available versions of Grubby AI—Version 1 and Version 2. Once you rewrite the same content to bypass AI detection, you will lose words from your subscription. Since Version 1 does not produce good output, you will try Version 2, you will to get the same result. In the end, you will finish your available words in a monthly or weekly subscription and be left with nothing but frustration. The Grubby AI service team is entirely uncooperative regarding refunds and does not respond. I would never recommend anyone waste their time and energy on it.
great tool to save time on school work. the best humanizer i've run into
Grubby.ai has helped me a lot. I really recommend to everyone who is still in school!
Good deal for the money. Would like to see support in Arabic next year but for now it is good
