What is ZeroGPT?

ZeroGPT calls itself a "trusted AI detection tool" that offers free AI content and ChatGPT detection. The official emphasizes high accuracy and ease of use, and it supports multiple languages. It is described by the official as "the most advanced and reliable detector for ChatGPT, GPT-5 and AI content". Detection supports both pasting text and uploading files. The results are highlighted sentence by sentence and the overall AI percentage is provided. The free mode has a single detection limit of 15,000 characters. In addition to text detection, the platform also offers image and video detection as well as a series of content tools, forming a complete toolbox around "AI content recognition and processing", which allows users to complete detection, rewriting and plagiarism check in one place.

Who is it for?

Writers, editors, and students who need to quickly check the AI-generated content ratio of their work, as well as teams engaged in content review that requires batch screening; users with a need to identify AI-generated images and videos can also use its extended detection capabilities. It is a common use case for self-media operators to check their manuscripts themselves and for content platforms to conduct pre-publication screenings.

Key features

AI Text Detection

Detects the proportion of text generated by AI (such as GPT-5, ChatGPT, Gemini, DeepSeek, Grok, etc.), and the official states that it is based on DeepAnalyse technology and a high-accuracy model.

Sentence-by-Sentence Highlighting

Each sentence is individually judged and highlighted, with the overall AI percentage provided, making it easy to locate problematic paragraphs and focus on revisions.

Batch File Upload

Supports uploading multiple files at once for batch detection, suitable for screening large volumes of content.

Multilingual Support

The official claims to support all languages, and non-English content can also be detected.

Report Generation

Can generate detection reports for easy storage, submission, and archiving.

Extended Detection

AI image detection, AI video detection (frame-by-frame analysis), to identify AI-generated image and video content.

Supporting Tools

Plagiarism check (covering billions of sources), grammar check, AI Humanizer rewriting, background removal, pomodoro timer, etc., covering the entire content processing workflow.

Multi-platform & API

Provides API access and can be used directly within WhatsApp and Telegram, aligning with daily toolchains.

How to use ZeroGPT

For daily self-inspection, the free quota is sufficient.
for important content, it is recommended to combine it with manual review and treat the test results as reference signals rather than final judgments.
If rewriting is needed after the test is completed, you can directly use the supporting Humanizer tool, and the processing flow will be closed-loop on the same platform.
For batch screening, first run a small sample to verify the consistency between the tool and manual judgment, then expand the scope of use, and it is recommended to interpret the test results of short texts with caution.
If you need to issue test conclusions externally, retain the report export and test time records for future review.
before testing, first clarify the purpose (self-inspection, delivery or review), and then select the corresponding workflow.

Things to know

AI detection is essentially a probabilistic judgment rather than an absolute conclusion: For text rewritten, co-written or generated by atypical models, the judgment results may be inaccurate. "Passing the detection" does not mean the content is of qualified quality, nor should it be used as the sole basis for academic research or review. The free mode has a character limit, and for bulk and high-frequency needs, it is necessary to evaluate API or paid solutions. When pasting sensitive text, pay attention to the destination of the content and privacy risks. The detection accuracy may vary across different languages and text types, and multiple verifications are recommended for important scenarios.
