Question 1

How does the AI detector work?

Accepted Answer

Our AI detector uses advanced natural language processing to analyze text patterns that distinguish human writing from AI-generated content. It examines sentence structure uniformity, vocabulary diversity, perplexity (predictability), burstiness (variation in complexity), and stylometric markers. The algorithm compares these patterns against known signatures of AI writing to provide an accurate probability score.

Question 2

Is this AI detector really free?

Accepted Answer

Yes, our AI detector is completely free to use with no hidden costs or premium tiers. You can analyze up to 10,000 characters per submission without any registration or account creation. Use it as many times as you need without daily limits or usage restrictions.

Question 3

Which AI models can be detected?

Accepted Answer

Our detector can identify content generated by all major AI models including ChatGPT (GPT-3.5, GPT-4, GPT-4o), Claude (all versions), Google Gemini, Meta LLaMA, and other large language models. The detection algorithm is regularly updated to recognize patterns from the latest AI systems.

Question 4

How accurate is the AI detection?

Accepted Answer

Our AI detector provides high accuracy for most text, but no detector is 100% accurate. Accuracy depends on text length (longer texts provide better results), the AI model used, and any post-editing applied. We provide confidence levels (low, medium, high) with each result so you understand the reliability of the detection.

Question 5

Can I check images and PDFs for AI content?

Accepted Answer

Yes! Our AI detector supports multiple input formats. You can upload images containing text (JPG, PNG, etc.) and we'll extract the text using OCR before analysis. You can also submit PDF documents for comprehensive content checking. All formats receive the same detailed analysis.

Question 6

What text length works best for detection?

Accepted Answer

For the most accurate results, we recommend submitting at least 150-200 words. The minimum requirement is 50 characters. Longer texts (500+ words) provide the most reliable detection because the algorithm has more data to analyze patterns and identify AI signatures.

Question 7

Do I need to create an account?

Accepted Answer

No account or registration required! Simply visit the page, paste your text or upload a file, and click detect. It's completely anonymous and instant with no signup process or personal information needed.

Question 8

Can AI-generated text be edited to avoid detection?

Accepted Answer

Heavily edited or paraphrased AI content may reduce detection accuracy. Our detector looks for subtle patterns that often persist even after editing, but significant human revision can make detection more challenging. We provide detailed indicator breakdowns to help you understand what specific patterns were identified.
