What is AI text detection?

AI text detection is the process of analyzing text to determine whether it was written by a human or generated by an artificial intelligence model. Our tool uses advanced machine learning algorithms to identify patterns and characteristics typical of AI-generated content. This involves examining factors like sentence structure, word choice consistency, and stylistic markers that differ from human writing. The technology is constantly updated to keep pace with evolving AI models.

How accurate is the detection?

Our detection model achieves high accuracy rates through continuous training on millions of text samples. However, no detection system is 100% accurate. For the most reliable results that match Turnitin's official standards, we recommend using our Advanced Mode. Accuracy can vary based on text length, quality, and the specific AI model used to generate the content. Users should interpret scores as probabilistic indicators rather than absolute proofs.

What is Advanced Mode?

Advanced Mode provides detection results that are 100% consistent with Turnitin's official AI detection system. It offers more detailed analysis, sentence-level detection, and comprehensive reports suitable for academic and professional use. This mode is designed for users requiring institutional-grade reliability, such as educators and researchers. The enhanced algorithms reduce false positives and offer deeper insights into detected AI segments.

Is my data secure?

Yes, your privacy is our top priority. All text submitted for detection is processed securely and is not stored on our servers after analysis. We do not share your data with third parties and follow industry-standard security practices. The no-signup requirement further minimizes personal data collection. Processing occurs in isolated sessions, ensuring documents remain confidential and are automatically purged immediately after evaluation.

What types of AI-generated text can be detected?

Our system can detect text generated by various AI models including GPT-3, GPT-4, ChatGPT, Claude, and other large language models. It works with academic papers, essays, articles, blog posts, and various other text formats. The algorithms are trained to recognize distinctive patterns from multiple AI architectures, providing broad coverage. Detection effectiveness may vary slightly depending on the specific model and prompt engineering used.

How long does detection take?

Detection is typically instant for most texts. Short to medium-length texts (up to 5,000 words) are analyzed in seconds. Longer documents may take slightly more time but generally complete within a minute. Processing speed depends on document length and server load, but performance is optimized for rapid turnaround. Users receive results via an intuitive interface without needing to refresh or wait extended periods.

Is there any limit on how many times I can use the detector?

No, the tool offers unlimited free detection without any restrictions on the number of scans or total words processed. Users can check as many documents as needed without encountering paywalls or subscription prompts. This unlimited access supports thorough review processes for educators and students alike. There are no daily, weekly, or monthly caps on usage, making it suitable for high-volume checking scenarios.

How does this detector differ from Turnitin's official AI detection tool?

While our free version provides strong alignment with Turnitin's standards, Advanced Mode delivers 100% consistent results matching Turnitin's official system. The primary difference lies in the depth of analysis and institutional integration features. Turnitin's tool is typically licensed to universities and integrated into their LMS, whereas our service offers direct public access. Both use similar underlying technology but differ in deployment and reporting formats.

Which browsers and devices are supported?

The tool is web-based and compatible with all modern browsers including Chrome, Firefox, Safari, and Edge. It works on desktop and laptop computers as well as tablets, but mobile phone support may be limited due to screen size constraints. Optimal performance requires a stable internet connection and up-to-date browser software. The responsive design adapts to different screen sizes, though larger displays improve usability for longer documents.

Can it detect AI-generated content in languages other than English?

Yes, the detection algorithms support multiple languages, though accuracy may vary for less common languages. The system is optimized for English texts but can analyze content in major languages like Spanish, French, German, and others with reliable results. Training data includes diverse linguistic samples, but performance is highest for languages with abundant AI-generated training corpora. Users should verify results for non-English texts as minor variations may occur.

What steps should be taken if a document is flagged as AI-generated?

If flagged, review the highlighted sections and consider revising those parts to incorporate more human writing patterns. Use the sentence-level analysis to understand specific markers. For academic submissions, consult with instructors about the results and potential next steps. The score indicates probability, not certainty, so contextual judgment is essential. Consider the document's purpose and original authorship before drawing conclusions based solely on the detection output.
