What it really isZeroGPT — AI-generated content detector for text across ChatGPT, GPT-4, Gemini, and other models.
Our takeZeroGPT is a freemium AI detection platform that scores text for the probability it was AI-generated using its proprietary DeepAnalyse™ Technology.
It is an AI detection tool with a freemium model: a free tier exists, and paid plans start at ~$9.99/mo. It supports multi-language detection, batch file uploads, plagiarism checking, and integrates via API for teams needing scale.
Why we rate itZeroGPT earns its place as a category default for casual AI detection: zero friction to start, reasonable free limits for light use, and an API path for developers.
Its sentence-level highlighting is genuinely useful for pinpointing suspect passages rather than just a headline score.
The catchAccuracy is self-reported at ~94% and real-world false-positive rates on paraphrased or lightly edited AI text can be high — it should be treated as a signal, not a verdict.
Free-tier character caps are tight for longer documents.

Best / not good for

Best for
  • Educators and academic institutions checking student submissions for AI authorship
  • Content teams and agencies enforcing human-written content policies at volume
  • Developers needing a low-cost AI-detection API to embed in publishing workflows
Not good for
  • Legal or compliance contexts requiring forensic-grade certainty (accuracy caveats apply)
  • Very short text snippets under ~250 words where detection confidence drops sharply
  • Enterprise teams needing SSO, audit logs, and SLA guarantees on the free or Pro tier
Trade-offs

Friction report

Trade-offs to know before signing up.

  1. Time to value
    Fast: paste text and get a scored result in seconds with no account required on the free tier.
  2. Scale breakpoint
    Per-plan character caps become a bottleneck for high-volume publishers; API pay-as-you-go is the escape valve but adds integration overhead.
  3. Walled garden
    Low: results are exportable as PDF reports; no proprietary format lock-in, and the API uses standard REST.
Still a fit?
If none of these block you, start on the free plan.

Frequently Asked Questions

What is ZeroGPT and what does it do?

ZeroGPT is an AI content detection tool designed to analyze text and predict whether it was written by AI models like ChatGPT, GPT-4, Gemini, Claude, or by humans. It provides detailed results showing the likelihood that parts of your content were generated by AI, helping users assess originality.

How does ZeroGPT detect AI-generated text?

ZeroGPT uses advanced NLP and machine learning algorithms to analyze sentence structure, word usage, and writing patterns. By comparing these linguistic features against patterns typical of AI-generated text, it estimates the probability that a given piece was created by an AI model.

What features does ZeroGPT offer?

ZeroGPT provides real-time detection of AI text, highlights which parts of text are likely AI-generated, and displays a percentage breakdown of AI vs. human-written content. It supports detection across multiple languages and can handle text pasted directly or uploaded from documents. Some versions also include API access and batch file detection.

Is ZeroGPT free to use?

Yes — ZeroGPT is available for free online and can analyze text without requiring account creation. Some versions or extended access (such as API or bulk detection features) may offer paid plans for professional workflows.

Who should use ZeroGPT?

ZeroGPT is useful for content creators, bloggers, educators, SEO specialists, and students who want to check if text appears to be AI-generated. It’s commonly used to evaluate content originality and ensure content alignment with publication or academic standards.
