How AIGuardian Works
Beyond keyword matching: sentence-level analysis, probabilistic confidence, and multimodal coverage so teams can document a fair review process.
Sentence-Level Analysis
Break documents into segments and highlight the exact phrases that trigger AI-pattern signals—so reviews stay explainable.
Explainable Confidence Scores
Get probabilistic confidence instead of a blunt yes/no, then combine scores with human judgment and source checks.
Multimodal in One Workflow
Run text, image, and video checks under one login—fewer tools to stitch for academic, editorial, and risk teams.

The Science of AI Detection
As large language models like ChatGPT, Gemini, and Claude advance, the line between human-written and machine-generated content continues to blur. Modern AI content detection relies on classifiers that analyze structural patterns—not simple keyword matching.
Our text models evaluate perplexity (how predictable the vocabulary is) and burstiness (variation in sentence length and structure). Because LLMs are predictive engines, they often produce low-perplexity, uniform prose; human writers introduce more spontaneous variety.
Beyond text, deepfakes and synthetic media from tools like Midjourney or Sora challenge digital authenticity. Our multimodal pipeline reviews image artifacts and temporal inconsistencies in video so educators, publishers, and security teams get explainable signals for informed decisions.

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?
AIGuardian is free to sign up, but detections require an active membership plan. Choose Basic, Pro, or Advanced based on your monthly volume; the mobile app also lets you earn detections by watching rewarded videos.
What modalities does AIGuardian cover?
One workflow covers AI text detection, AI image detection, and deepfake video analysis. Use product tools for scanning; use solution guides when you need ChatGPT-, Gemini-, essay-, or deepfake-specific review playbooks.
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. Detection models are updated as new generators ship.
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 bypass-oriented review signals trained to flag text modified by paraphrasing and humanizer tools.
Is my data secure?
Yes. Content is analyzed over encrypted connections. Uploaded files are deleted after analysis completes and are not retained as a permanent archive.
How should teams use detector scores?
Treat scores as signals, not verdicts. Combine highlights with writing history, source checks, and human review before academic, editorial, or trust-and-safety decisions.
