This was an horrible experience, I canceled my subscription last month which costs 19.99 per month. Today they charged my 24.99 USD!!!! What the hell? I'm confident that my subscription was canceled, but even if it wasnt, I should be charged 19.99 for another month, how the hell can they charge me 24.99 out of the blue? This is a horrible website, they dont even let me remove my card from their website. NOT SAFE. DO NOT USE!

Similar to clever AI humanizer, but somehow even worse. I didn’t know it could get any worse, but clearly Grubby AI made that possible. Stay away from this horrid software. If you use it, you aren’t getting anything above a D in your classes. It makes you sound like you are special in the head, all that while not being able to bypass any detection tools. The award for fastest way to getting an academic explosion goes to Grubby AI 😂✌🏼 🎉🎉🎉 just use a better humanizer like Walter

AVOID THIS HUMANIZER, ITS TRASH. I feel like I am doing a disservice to trash by calling this trash. I first discovered this on TechJoyce's YouTube and was a little skeptical mostly due to the eyesore UI, even AI can't create a UI that looks that bad. Half of the buttons don't even function properly and everything is just so confusing on this website. It's like he did this on purpose. That was not even the worst of it at all, this guy is changing his free plan every day, it's like he can't make up his mind. I really should've read these reviews prior to using this trash service. Even the other reviews that are made about this from other services like Ryne talk about how this is trash. The humanizer doesn't work, and the whole site is a bunch of AI slop and garbage. This is just a GPT wrapper that pays creators that you would think would promote good products but instead promote straight trash that nobody will benefit from. This is easily one of the worst humanizers. I looked even more deep into the reviews and supposedly he had another humanizer website that he had to shut down from the reviews, clearly this is going down the same path. This is insane, I'm never using this again and I would advise to stay away from this at all costs.
WARNING: Grubby deducted $19.88 without my consent, and they didn't reimburse me this amount. It seems, I have to escalate this. Case: I paid for 1 month subscription. But the Grubby system didn't work on my laptop. It was full of bugs and error messages popping up here and there. So I wanted to cancel the subscription. During the cancellation process, their system offered me 1 month subscription for free, starting after my paid subscription. So I fell for it, trusted them, and reconsidered my cancellation, and agreed. I thought, ok, let's give them a chance to fix this. However, I was very surprised after I saw that they didn't provide me that month for free, but deducted a 1-month fee of $19.88 instead. After contacting them maybe 6-7 times, I got 1 response (maybe after 1 week or so). But no solution. No money back. Nothing. No reaction. This looks like fraud in my eyes.
Totally unstable output. Sometimes, it changes the topic completely. Sometimes, it says that the output is AI-free, but when I check using GPTZero, it says 100% AI. The tool is unreliable; it does not do what's promised. I asked for the refund, but they did not issue it.
Seemed promising using it with around 300 words, which they offer on the free plan. Then I signed up for the Enterprise plan. Complete gotcha, is what it feels like. You could call the outputs humanized, if that human is a first-grade level writer with the attention span of a gerbil. The humanized writing starts off barely readable, and by the end has devolved into utter nonsense. The only thing that's true is it will pass as human-written, but that's because it just becomes a string of random words that have zero coherence. You would get a better result by slamming your head against the keyboard, and that's said sincerely. Quality issues aside, when asking for a refund on this obviously useless product, you'll just get an email stating that you agreed never to receive a refund, and all sales are final. Don't waste your time or money on this service.
Completely worthless garbage. Doesn't even work. Do NOT purchase.
It ruined the sound of my essays
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.
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.
