How Do AI Detection Tools Work? A Breakdown By Content Type

Many users are only familiar with text-focused ai detection tool options, but modern AI detection covers far more than written content. Ai.Rax’s advanced models use specialized technical frameworks to analyze each content type for unique AI-generated patterns, delivering accurate results even for heavily modified content. Below, we break down the core principles behind each detection modality, with real-world examples of how they work.

Text Detection: Spotting AI Writing Even When Users Attempt to Remove AI Detection From Essay Submissions

Text is the most widely used AI-generated content type, spanning student essays, marketing blog posts, social media captions, and professional reports. AI large language models (LLMs) generate text by predicting the most statistically likely next word in a sequence, trained on billions of words of public content. This process leaves consistent, identifiable fingerprints that Ai.Rax’s text model is trained to spot, even when users modify the content to evade detection.

The core technical features Ai.Rax analyzes for text include:

• Perplexity: A measure of how surprising or unpredictable the next word in a sequence is. Human writing has high perplexity, as we use unusual turns of phrase, make small grammatical errors, and shift topics naturally. AI writing has consistently low perplexity, as it prioritizes the most common, expected word choices to produce coherent, generic output.

• Burstiness: A measure of variation in sentence length and structure. Human writers mix short, punchy sentences with long, complex, meandering ones, while AI writing tends to have extremely uniform sentence length and structure across an entire piece of content.

• Semantic and structural patterns: Ai.Rax’s model is trained on output from every major LLM, so it can identify unique patterns in how different models structure arguments, use idioms, and transition between topics, even when surface-level word choice has been heavily modified.

A common use case for text detection is for educators grading student submissions. Many students attempt to remove AI detection from essay submissions by running AI-generated text through paraphrasing tools, swapping out 10-15% of words for synonyms, or manually rewriting small sections. However, these modifications only change surface-level features of the text, not the underlying structural and statistical patterns that Ai.Rax analyzes. For example, a student might generate an essay on renewable energy with an LLM, run it through a paraphraser to change every fifth word, and submit it as original work. Ai.Rax will still flag the essay as 90% AI-generated, highlighting the specific sections that match LLM output patterns, so educators can have full confidence in the results.

Image Detection: Identifying AI-Generated Visuals Even After Heavy Editing

AI image generators have made it easier than ever to create photorealistic visuals for marketing, social media, and creative projects, but they also leave unique artifacts that Ai.Rax’s image model is designed to detect. Unlike human photographers or designers, who create images through physical capture or manual editing, AI image generators build visuals pixel by pixel, based on training data of millions of existing images. This process leaves both visible and invisible signatures of AI generation.

Ai.Rax’s image detection analyzes two core sets of features:

• Visible artifacts: Common visible flaws in AI-generated images include distorted human hands or fingers, inconsistent lighting and shadows across small objects, text that is unreadable or nonsensical, and unnatural texture on fabric, skin, or natural surfaces like grass or water.

• Invisible frequency domain patterns: When you run a Fourier transform on an AI-generated image, you will see unique noise patterns that are not present in human-created or photographed images. These patterns are invisible to the naked eye, but they remain even after heavy editing, including color correction, cropping, retouching, or overlaying text or other elements.

For example, a marketing team might receive a set of product photos from a freelance designer, who claims they shot the photos in a custom studio. After running the images through Ai.Rax, the team finds that the images are AI-generated, as they carry the unique frequency noise signature of a popular AI image generator, even though the designer retouched the images to fix visible distorted edges on the product. This saves the team from potential copyright issues, as AI-generated images often have unclear copyright status depending on the jurisdiction.

Audio Detection: Spotting AI Voiceovers and Deepfake Speech

AI voice generators can now replicate any human voice with near-perfect accuracy, creating huge risks for fraud, impersonation, and misinformation. Ai.Rax’s audio detection model analyzes thousands of micro-features of audio content to spot AI-generated speech and music, even when the audio has been edited with background noise, effects, or pitch adjustments.

Core technical features analyzed for audio include:

• Prosody consistency: Human speech has natural variability in pitch, pace, stress, and intonation depending on context. We speed up when excited, slow down when thinking, and vary the emphasis on different words to convey meaning. AI-generated speech has extremely uniform prosody, with little natural variation across a clip.

• Disfluency patterns: Human speech naturally includes small disfluencies like “um”, “uh”, pauses, and stutters that are unpredictable and context-dependent. AI models either omit these disfluencies entirely, or add them in predictable, repeated patterns that stand out to Ai.Rax’s model.

• Spectral signatures: AI-generated speech has unique patterns in the frequency spectrum that differ from human speech, particularly in the higher frequency bands that carry subtle details of voice production.

A common real-world use case is for fraud prevention. A small business owner might receive a phone call or voicemail claiming to be from their bank representative, asking for sensitive account verification details. By uploading the audio clip to Ai.Rax, they can quickly confirm that the voice is AI-generated, even if the scammer added background office noise to make the call sound authentic, avoiding a potentially costly fraud attempt.

Video Detection: Uncovering Deepfakes Through Multi-Layer Analysis

AI-generated video (deepfakes) are one of the most dangerous forms of AI content, as they can be used to spread misinformation, defame individuals, and commit fraud. Ai.Rax’s video detection model combines three layers of analysis to deliver accurate results, even for short, low-quality clips shared on social media.

The three layers of Ai.Rax’s video analysis are:

1. Per-frame visual analysis: Each frame is analyzed for the same AI image artifacts and frequency patterns described above, to spot AI-generated visual content.

2. Audio analysis: The full audio track is analyzed for AI-generated speech, music, or sound effects, as well as sync issues between audio and visual content.

3. Temporal consistency analysis: Ai.Rax analyzes frame-to-frame changes to spot unnatural shifts in objects, faces, or backgrounds that do not follow the laws of physics. For example, a button on a shirt might shift position between frames, or a strand of hair might move in an unnatural way, as AI video generators often struggle to maintain perfect consistency across frames.

For example, a public figure might find a short viral video clip of themselves making an offensive, out-of-character statement circulating on social media. By running the clip through Ai.Rax, their team can confirm it is a deepfake: the model spots that the lip movements do not perfectly align with the audio, and the background street sign behind the figure shifts position slightly across frames, a clear sign of AI generation. This allows the team to respond quickly with proof that the video is fake, minimizing reputational damage.
