It's tough to tell if text was truly written by a person or a machine. Many professionals and academics feel unsure about the authenticity of content they receive. GPTZero is here to help.

It's the first and leading AI detector that identifies specific passages generated by an LLM. This tool provides the clarity and confidence you need. ✨

Czym jest GPTZero?

GPTZero is a dedicated AI content checker that recognizes machine-generated text in any document. This powerful proprietary model helps you identify exactly which parts of a text originated with a large language model (LLM).

How does it work? It analyzes text for key patterns that distinguish machine writing from human writing. These factors include checking for predictability (perplexity), variation in sentence structure (burstiness), and whether the tone is overly generic or repetitive.

Since its founding in January 2023, GPTZero has quickly become essential. It has served over 10 million users and is used by hundreds of institutions, especially in education. It is truly built for contexts where authentic and quality writing matters most. 💡

GPTZero Kluczowe funkcje

✅ Proven, Industry-Leading Accuracy

You need a detector you can rely on, especially when dealing with critical documents. GPTZero provides necessary assurance backed by strong performance. Independent benchmarks, including studies from Penn State’s AI Research Lab, confirm its performance.

This tool maintains an exceptional 99% accuracy rate when distinguishing between human and AI writing. Critically, its false positive rate is kept under 1%. This means the chances of misclassifying authentic human writing as machine-generated are extremely low. G2 also ranked GPTZero the #1 most trusted and reliable AI tool in 2025.

✨ Deep Analysis of Writing Patterns

GPTZero uses a powerful proprietary model dedicated to recognizing machine-generated text in any document. The model analyzes text for subtle patterns that differentiate LLM output from human authorship. It considers hundreds of factors to identify specific passages generated by a machine.

The core of the system works by checking for these three key elements during a scan:

Perplexity: Checks if the writing is overly predictable.
Burstiness: Measures the variation in sentence structure and length.
Style: Evaluates if the tone is overly generic or repetitive.

✨ Advanced Interpretability and Transparency

GPTZero believes in full clarity regarding its findings. It is the only detector that transparently explains exactly why text is flagged as machine-written. This feedback uses natural language explanations that are easy to understand.

Results are visually displayed using color-coded highlights. These highlights point out the specific phrases and sentences where AI content was detected. This provides accurate, sentence-level insight into the text's potential origin.

✨ Reliability for Mixed and Non-Native Content

Working with complex documents demands reliable analysis. Unlike many competitors, this tool reliably handles “mixed documents” that contain both human and AI writing. It maintains a strong 96.5% accuracy even in these challenging scenarios.

GPTZero is also the only AI detector de-biased for English Second Language (ESL) learners. Its models are repeatedly trained specifically to reduce the false positive rate for ESL writing. The commitment ensures the false positive rate for ESL content remains at just 1%.

🌐 Broad LLM and Language Coverage

The model is designed to work across a wide range of available large language models. It successfully detects text from all major platforms, including ChatGPT, Gemini, and Claude, among others. The detector is accurate regardless of which specific AI model may have produced the text.

GPTZero also fully supports five key languages with industry-leading accuracy. These fully supported languages are English, German, Portuguese, French, and Spanish. Furthermore, the tool is constantly used in many other languages across over 100 countries.

✨ Simple Scanning and Workflow Tools

You can start determining the source of your text immediately. Simply paste your content or upload a file for review and press ‘Scan’. GPTZero will immediately suggest the percentage of your content that is likely AI-generated.

For ongoing use, the platform offers a dedicated Chrome Extension. This extension allows you to view AI detection and typing pattern metrics on web pages and Google Docs. This makes spotting AI-created content easier during your normal workflow.

📚 Maintaining Academic Trust

Educators often struggle to confirm the source of student work. Since GPTZero is used in thousands of colleges and institutions, it’s the trusted solution for academic integrity.

A teacher can quickly submit an essay to check for machine usage. If AI is detected, the tool provides color-coded highlights showing the exact phrases written by the LLM. This specific feedback guides discussions, helping teachers support students while upholding honest practice. The specialized model also ensures ESL learners are not unfairly flagged, protecting diverse student populations.

💼 Vetting High-Stakes Hiring Materials

When recruiting for roles that require strong communication, vetting writing samples is crucial. You need confidence that a candidate’s submission accurately represents their skills, not AI polish.

Problem: A recruiter must handle dozens of applications while ensuring authenticity. Approach: They use the Professional plan, which allows scanning up to 250 files at once. GPTZero analyzes the texts for AI patterns like unusual predictability (perplexity) and lack of sentence variation (burstiness). Expected outcome: The hiring team gains certainty about which candidates possess genuine, human writing talent.

📰 Ensuring Content Integrity for Publishers

Publishers, marketers, and legal teams cannot risk publishing content that is fully or partially machine-generated. Authenticity is key to maintaining reader trust and quality standards.

GPTZero is reliable even when a document mixes human and AI content. The tool correctly identifies these 'mixed documents' with 96.5% accuracy. Upload your submission and receive a detailed report that shows precisely why a text is flagged as machine-made. This transparency ensures decisions are well-grounded.

✍️ Improving Writing Style and Originality

Many writers want to ensure their voice sounds human and engaging, not overly generic or repetitive. GPTZero works as a writing coach by identifying characteristics associated with machine text.

You can use the Premium features to polish your drafts. The tool offers Writing Feedback, Grammar checks, and AI Vocabulary assistance to help you sound more dynamic. This process ensures your content is authentic and high quality before you submit it for review.

Tip: Focus on reducing predictability metrics. Inject more varied sentence structure and specific language into your writing to sound more human.

🌍 Handling Multilingual Content Checks

Organizations working internationally need reliable detection across languages. GPTZero supports English, German, Portuguese, French, and Spanish with industry-leading accuracy. It is also used globally in over 100 countries.

This broad language coverage, combined with the assurance that the model is de-biased for non-native speakers, makes it ideal for global operations. You can reliably check team reports or collaborative documents without risking false positives on authentic, human-written content.

Recenzje użytkowników

Users reviewing GPTZero present two distinct experiences. Positively, many educators and professionals find the tool quick, efficient, and useful for validation, noting its effectiveness in identifying purely machine-generated text or confirming genuine human submissions.

Some users praise the free plan for providing a valuable summary of potential AI use. However, a significant portion of feedback focuses on fundamental reliability and transparent business practices.

The most frequent complaint is that the detection model is highly unreliable, frequently triggering false positives on authentic human-written content, even flagging standard quotes or eloquent sentences as AI. Beyond accuracy concerns, the service faces intense criticism regarding customer support and billing transparency.

Users reported zero support responsiveness and significant difficulties canceling subscriptions or trials, often leading to unauthorized yearly charges when they expected monthly billing. This lack of clear cancellation procedures and poor support severely detracts from the app’s perceived value and reliability.

5.0 / 5

This detector is excellent and accurate. Text written from scratch is very rarely detected as AI, which is what I needed. I have tested it on different writing types and found it very reliable.

Leo S.

It’s fast, easy to use, and gives a clear breakdown of results. I really enjoy the summary even on the free plan. I recommend it to others.
