AI Image Detector —
Check Any Photo or Social Post for AI
Paste a post link from X or Reddit — or drop in any image URL — and find out if it was generated by AI. No file download required.
5 free scans per day
No signup for first scan
Results in under 10 seconds
TL;DR
KweliAI is a free AI image detector that works from social media post URLs — paste a link from X or Reddit and it checks whether the photo or video is AI-generated without requiring a file download. Three detection models run simultaneously on every scan: AI image detection, deepfake analysis, and AI audio detection. Free for 5 scans per day on X and Reddit. Pro unlocks all six platforms with unlimited scans.
Process
How It Works
Three steps. No account required to start, no file to download.
1
Paste a link or enter an image URL
Drop in a post URL from X or Reddit (free), or from TikTok, YouTube, Instagram, or Facebook (Pro). Any publicly visible post with an image or video works.
2
KweliAI retrieves and analyses the media
The image or video is extracted directly from the platform at source quality. Three detection models run simultaneously — AI image, deepfake, and AI audio — analysing pixel-level and frequency-domain patterns that generative models leave behind.
3
Read the clarity score and verdict
A score from 0 (definitively real) to 100 (definitively AI-generated) is returned alongside a plain-language verdict and a confidence rating of high, medium, or low. Results typically arrive in under 10 seconds.
Why start from a URL rather than a file? Most detectors require saving the image first, then uploading it somewhere else. If the image is in a post on X, there is no native download option. On Instagram, there never has been. On TikTok, downloads come with watermarks that degrade detection quality. KweliAI skips that step entirely — paste the link and the extraction happens server-side on the original unmodified file.
Methodology
How Accurate Is This, Really?
Most AI image detectors return a percentage and nothing else. That is not enough information when the result affects a real decision — a job offer, a match, whether to share a video.
Here is what the detection actually measures:
Pixel-level frequency domain patterns characteristic of generative models — the statistical fingerprints that Midjourney, DALL-E, Stable Diffusion, Flux, and similar tools embed in their output regardless of how convincing the image looks visually
GAN fingerprints and diffusion model artifacts that persist even after compression and re-encoding — relevant for images that have been shared and re-shared across platforms
Facial boundary consistency, blinking patterns, and temporal frame analysis for video deepfake detection
Spectral patterns and prosodic naturalness for AI-cloned audio in video content
No detector is 100% accurate. Heavily compressed, cropped, or post-processed images are harder for any model to score reliably. KweliAI flags these cases explicitly — when confidence is medium or low, that rating is part of the result, not hidden behind a false certainty score. If something looks off but scores with low confidence, treat it as one signal among several and combine it with a reverse image search and manual review of the account.
Comparison
KweliAI vs Other AI Image Detectors
The AI image detection market splits into two categories: consumer tools that require file uploads, and enterprise APIs that require integration and commercial contracts. KweliAI is the only consumer tool that works from social media post URLs directly.

Questions
Frequently Asked Questions
Is there a free AI image detector?
Yes. KweliAI provides 5 free AI image detection scans per day on X and Reddit with no account required for the first scan. A Pro plan at $12 per month or $99 per year unlocks unlimited scans across TikTok, YouTube, Instagram, and Facebook as well.
How accurate are AI image detectors?
No AI image detector is 100% accurate. KweliAI returns a confidence score rather than a flat verdict and explicitly flags cases where the result is less reliable — heavily compressed, cropped, or edited images are harder to score for any detection model. A high-confidence result is more actionable than a medium or low-confidence one.
Can I check an image directly from a social media post without downloading it?
Yes. KweliAI works directly from post URLs on X and Reddit (free) and TikTok, YouTube, Instagram, and Facebook (Pro). Paste the post link and KweliAI extracts and analyses the image server-side. No download to your device is required — which matters on platforms like X and Instagram where downloading is restricted or unavailable.
What AI image generators can KweliAI detect?
KweliAI detects images generated by Midjourney, DALL-E, Stable Diffusion, Adobe Firefly, Flux, StyleGAN, and similar generative models. Detection works by analysing pixel-level and frequency-domain patterns that AI generation processes leave behind, not by relying on metadata or visible watermarks which are easy to remove.
Does KweliAI detect deepfake videos as well as AI images?
Yes. Three detection models run simultaneously on every scan — one for AI-generated images, one for deepfake face and body manipulation, and one for AI-cloned audio in video content. The same URL-based workflow applies to both images and videos from supported platforms.
How is KweliAI different from ZeroGPT, NoteGPT, or Hive Moderation for AI image detection?
ZeroGPT and NoteGPT require file uploads and do not support social media post URLs. Hive Moderation is an enterprise API product requiring developer integration and a commercial contract — it has no consumer-facing scan interface. KweliAI works directly from post URLs across six social media platforms with a free tier and no signup required for the first scan.
