detects what is real

A plain-English guide to AI content detection — how it works, what it detects, and why it matters in a world of deepfakes and AI-generated media.

What is an AI content detector?

An AI content detector is a tool that analyses images and videos to determine whether they were created by a human or generated by artificial intelligence. As AI image and video generation tools have become widely accessible — Midjourney, DALL·E, Stable Diffusion, Sora, Runway, and dozens of others — the ability to distinguish real content from synthetic content has become essential.

AI-generated content leaves behind subtle fingerprints. These include unnatural pixel-level patterns, inconsistent lighting and shadow behaviour, frequency artifacts invisible to the human eye, and statistical anomalies in how colour and texture are distributed across an image or video frame. Detection models are trained to recognise these signals by learning from thousands of known examples of both real and AI-generated content.

"KweliAI is a free AI content detector for social media. Paste any public post link from X, Reddit, TikTok, YouTube, Instagram or Facebook and receive a verdict — real, AI-generated, or deepfake — in seconds."

How AI detection works

KweliAI runs three deep learning models in parallel on every scan. Each model is trained to detect a different category of AI-generated content:

AI image model — detects images generated by tools like Midjourney, DALL·E, Stable Diffusion, and Adobe Firefly. Analyses pixel frequency patterns, GAN fingerprints, and diffusion model artifacts.
Deepfake model — detects videos where a real person's face or body has been digitally manipulated. Analyses facial boundary consistency, blinking patterns, skin texture coherence, and temporal frame consistency.
AI audio model — detects AI-generated or cloned voices in video content. Analyses spectral patterns, formant consistency, and prosodic naturalness that differ between human and synthetic speech.

The outputs of all three models are combined into a single clarity score between 0 and 100, where 0 is definitively real and 100 is definitively AI-generated. A confidence rating — high, medium, or low — is also returned to indicate how certain the verdict is. KweliAI achieved 99.01% accuracy on the 2025 Braintrust model validation benchmark.

How deepfake detection works

A deepfake is a video or image in which a real person's face, voice, or body has been manipulated using AI. The term comes from "deep learning" and "fake" — the technology uses neural networks to convincingly replace or alter a person's appearance or voice in media.

Deepfakes are increasingly used in scams, political misinformation, non-consensual intimate imagery, and impersonation attacks on social media. They have become sophisticated enough that visual inspection alone is often insufficient to identify them.

KweliAI detects deepfakes by analysing signals that AI manipulation leaves behind:

Unnatural blinking frequency and eye movement patterns
Facial boundary artifacts where the swapped face meets the original
Skin texture inconsistencies under different lighting conditions
Temporal inconsistencies between frames that real video does not exhibit
Audio-visual desynchronisation where lip movements don't precisely match speech

To check if a video is a deepfake, copy the social media post link and paste it into KweliAI. The tool downloads the video, analyses every frame, and returns a verdict with a confidence score.

How to detect AI-generated dating profile photos

Romance scammers increasingly use AI-generated profile photos to create convincing fake identities on dating apps and social media platforms including Tinder, Bumble, Hinge, Instagram, and Facebook. These AI-generated faces are created using tools like Midjourney, ThisPersonDoesNotExist, and custom GAN models trained to produce photorealistic human portraits.

Modern AI face generators have become so realistic that traditional visual cues — looking for blurred backgrounds, oddly shaped ears, or asymmetrical features — are no longer reliable. AI tools have learned to avoid these tells.

The most reliable way to check if a dating profile photo is real is to use a dedicated AI detection tool. If the person has a social media profile, you can paste the link to their post directly into KweliAI. If you only have the image file, save it and share it to a public post on X or Reddit, then paste that link into KweliAI for analysis.

"If someone you met online seems too good to be true, their profile photo may be AI-generated. KweliAI can help you verify — paste a link to their social media post and get a verdict in seconds."

KweliAI analyses the image using models specifically trained to detect AI-generated faces, including portraits created by Midjourney, DALL·E, Stable Diffusion, and StyleGAN. The result includes a confidence score so you know exactly how certain the verdict is.

How to detect AI-generated videos on social media

AI-generated videos are becoming increasingly prevalent on platforms like TikTok, YouTube, Instagram, Facebook, and X. Tools like Sora (OpenAI), Runway, Pika, and Kling can now generate photorealistic video from a text prompt in minutes, making it difficult to distinguish synthetic video from footage captured by a real camera.

AI-generated videos contain hidden generation artifacts that differ from real camera footage:

Unnatural motion blur that doesn't correspond to real camera physics
Inconsistent object permanence — objects appearing or disappearing between frames
Frequency domain patterns that differ statistically from real camera sensor noise
Temporal inconsistencies in lighting and shadow that real environments don't produce

To detect an AI-generated video on social media, copy the post URL from TikTok, YouTube, Instagram, Facebook, or X and paste it into KweliAI. The tool extracts the video, runs it through three detection models simultaneously, and returns a verdict with a confidence score in under 10 seconds. Free users can scan posts from X and Reddit. Pro users can scan all six platforms with unlimited scans.

Which platforms KweliAI supports

KweliAI supports six major social media platforms. Paste any public post link from these platforms and KweliAI will extract and analyse the image or video:

𝕏 X / TwitterFree & Pro
RedditFree & Pro
TikTokPro only
YouTubePro only
InstagramPro only
FacebookPro only

KweliAI can only scan posts that are publicly visible without signing in to the platform. Private posts, protected accounts, and content behind paywalls cannot be scanned.

Is KweliAI free?

Yes. KweliAI is free to use with no credit card required. Free accounts include 5 scans per day on posts from X and Reddit. There is no trial period — free users keep their access indefinitely.

Pro accounts include unlimited scans across all six supported platforms for $12 per month or $99 per year (equivalent to $8.25 per month). Pro users can scan TikTok, YouTube, Instagram, and Facebook posts in addition to X and Reddit. Both free and Pro accounts use the same detection models with 99.01% accuracy.

KweliAI Pro is designed for journalists, researchers, fact-checkers, and anyone who needs to verify social media content at scale. Cancel any time — there are no long-term contracts.
