What is ZeroGPT?
ZeroGPT is for people reviewing texts for likely AI-generated passages or similarities to published texts. It also offers rephrasing, document summaries, grammar and spelling correction, and PDF detection reports.
According to its documentation, ZeroGPT lets you:
- flag passages likely generated by AI
- look for similarities to published texts
- rephrase text
- summarize a document
- correct grammar and spelling
- produce a PDF detection report
We file it under AI content detection, the category of tools to check whether content is AI-made, and it also overlaps with grammar and paraphrasing and aI summarisers. The category lists 9 verified tools on this site.
The publisher is Olive Works LLC, based in United States. The service launched in 2023, which gives it some track record.
Who is it for?
It is mostly useful to these profiles: teachers, students, content writers, and marketers. The need it covers is simple to state: check whether content is AI-made.
ZeroGPT is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you must keep your data in Europe or on your own machine
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does ZeroGPT cost?
Pricing model: freemium (limited free use, then paid). A free plan is offered, usually limited in volume or features.
The entry price is not shown publicly: you have to contact the publisher or create an account to see it.
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
According to its privacy policy, data is processed in the European Union.
Hosting in the European Union makes GDPR compliance easier, without exempting you from reading the terms of use.
Exporting your content: PDF. Being able to get your data back makes switching tools easier later.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
ZeroGPT runs on: web browser and API.
Interface languages: English, French, German, Spanish, Italian, and Portuguese.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
