## What is AIZero?

Introducing the revolutionary AI Detection App - your ultimate tool to unravel the mysteries hidden in texts! Our app is at the forefront of AI detection, designed to determine whether a document was written by a human or generated by an AI model.

Using cutting-edge artificial intelligence detection model, our app delves into texts on a sentence, paragraph, and document level, analyzing language intricacies to distinguish human-written prose from AI-generated content. We have trained the model on an extensive and diverse collection of human-written and AI-generated texts, with a strong focus on English prose, ensuring the highest accuracy in detecting essays crafted by AI models.

For academic integrity, we've adopted a premium model specifically trained to identify AI-authored essays masquerading as student writing.

### 1/5 — App is not working

*2026-08-12*

It's saying that I need an updated version but there isn't an updated version to download. Now the app doesn't work!

### 1/5 — Stopped working

*2026-06-03*

I paid for the premium version and all of a sudden stopped working. I reached out to customer support and have not had any response. Disappointing.

### 1/5 — Rik

*2026-05-23*

AIZero-AI Detector has completely stopped working. Also, there is no way to communicate with the company on how to correct the problem.

The company will not issue me a refund.

### 1/5 — Suddenly stopped working

*2026-05-18*

App suddenly stopped working because the version was outdated but no provisions were made for persons who paid for the app. Unable to find upgraded version in app store. Has not worked in over a month. I WANT MY MONEY BACK!

**Developer response:** Hi, sorry to let you get this bad experience, we have improved our backend server to fix this issue. If you have any questions, please feel free to contact us at contact@bridgeshullltd.com

### 1/5 — No happy

*2026-04-29*

It kept on giving me an error message after I paid for my subscription. Definitely not happy with that.

### 5/5 — What is happening?

*2026-04-25*

The app stoped working! It says that is not updated but there’s not an update! I have the premium version and it is failing in everything

### 1/5 — Unbrauchbar für Schule und Uni

*2026-01-13*

Also wenn wir Lehrer und Professoren auch noch das zweifelhafte Resultat unserer pädagogischen Bemühungen auch noch per Hand eintippen müssen, dann sind wir wirklich reif für die Klapsmühle. Das ist ja wohl ein Witz oder?

**Developer response:** Hi, sorry to let you get this bad experience, we have improved our appr to fix this issue. If you have any questions, please feel free to contact us at contact@bridgeshullltd.com

### 1/5 — Hidden Purchase

*2025-12-07*

If you really want people to join your service make it immediate on the App Store.  You can’t do anything with the free version.  I do not recommend for casual usage and although I haven’t used it if you intend on actually using one of these softwares use a much better one like ChatGPTZero.😣

**Developer response:** Hi, sorry about that. We’ve optimized our product and now offer limited usage in the free version so users can try the app before upgrading. If you have any questions, please feel free to contact us at contact@bridgeshullltd.com

### 1/5 — Is wrong

*2025-08-20, version 1.7*

Wrong

### 1/5 — Don't Even Bother… No Trial Before U Buy

*2025-07-23*

The description is correct, but it doesn't allow you to see how well it works. Normally, that's all you need to know. If a company wanted you to test drive a car before purchasing, would you buy from them? That's what this App is doing.

**Developer response:** Hi, sorry about that. We’ve optimized our product and now offer limited usage in the free version so users can try the app before upgrading. If you have any questions, please feel free to contact us at contact@bridgeshullltd.com
