Frequently Asked Questions
How does AIGuardian detect AI-generated content?
AIGuardian uses trained machine learning classifiers to analyze linguistic patterns, visual artifacts, and temporal inconsistencies across text, images, and video. The results are probabilistic confidence scores that should be combined with human judgment for final decisions.
Is AIGuardian free to use?
Yes, AIGuardian offers a free tier with daily quotas for text, image, and video detection. You can evaluate the platform at no cost before upgrading to Pro or Advanced plans for higher limits and additional features.
What AI models can AIGuardian detect?
AIGuardian can detect content generated by ChatGPT (GPT-4, GPT-4o, GPT-5), Google Gemini, Claude, Deepseek, Grok, and other major large language models. Our detection models are continuously updated as new AI models are released.
Can AIGuardian detect AI-generated images?
Yes. Our AI Image Detector analyzes visual artifacts, metadata signatures, and pixel-level patterns to identify images created by Nano Banana, Flux, Midjourney v7, Grok Imagen, DALL-E, Stable Diffusion, and other AI image generators.
How accurate is AI content detection?
No AI detector is 100% accurate. AIGuardian provides probabilistic confidence scores designed to minimize false positives. Results should be used as evidence signals alongside human review, source verification, and context analysis.
Can AI detectors be bypassed by humanizer tools?
Some AI humanizer tools attempt to evade detection by altering sentence structure and vocabulary. AIGuardian includes advanced bypass detection capabilities specifically trained to identify text modified by paraphrasing and humanizer tools.
Is my data secure?
Yes, we prioritize data privacy. Your content is analyzed securely using encrypted connections and is not stored permanently. Uploaded files are automatically deleted after analysis is complete.
What is the best AI detector for students with a low false positive rate?
For students, minimizing false positives is critical to avoiding unfair academic penalties. AIGuardian is designed with a very low false positive rate by combining linguistic analysis with confidence masking, ensuring that human-written essays are not mistakenly flagged as AI-generated.
How to prove a student essay was not AI generated?
If an essay is falsely flagged by a basic detector, you can prove it was not AI generated by using a more advanced tool like AIGuardian which offers sentence-level explainability. Providing your version history, draft outlines, and running the text through AIGuardian can help verify the human effort behind the work.
