Our Proprietary Model & Detection Statistics
Engineered with multi-signal forensic triangulation and benchmarked on 843 hardened evaluation stress tests across frontier AI generators.
Multi-Signal Forensic Detection Layers
Aspect-Preserving 25-Bucket ViT-S/16
Standard detectors center-crop images to 224×224, throwing away ~45% of width on 16:9 photos. Our ViT-S/16 maps images into 25 native aspect buckets with baked position embeddings, inspecting entire canvases without center-crop distortion.
21 Deterministic Spectral & Noise Features
Computes 2D Fast Fourier Transform (FFT) radial spectral slope, 3×3 high-pass filter excess kurtosis (hf_noise_kurtosis), Bayer Color Filter Array (CFA) demosaicing traces, and gradient entropy to isolate synthetic diffusion noise from camera optics.
Cryptographic Provenance (SynthID & C2PA)
Inspects imperceptible Google SynthID digital watermarks and cryptographically validates C2PA Content Credentials manifests to instantly identify declared AI generation or camera hardware provenance.
12-Strategy Human-Grounded Forensic Harness
When neural logits fall in ambiguous bands (0.35–0.85), an automated 12-strategy verification harness cross-evaluates localized facial boundary seams, color-temperature shifts, and PRNU sensor noise discontinuities.
Hardened Evaluation Benchmark Results
Empirical metrics from our v0.6.0 model benchmarked across 843 curated stress-test images (410 synthetic, 433 camera authentic) spanning 6 lossy degradation views.
Macro Mean ROC-AUC
Balanced Accuracy
Unseen 2026 Frontier Generators
Stress-tested against completely unseen generative models (Midjourney v6, Flux.1, SD3, DALL-E 3, Imagen 3) without fine-tuning.
Viral Social Media Posts & Memes
Benchmarked on contested community submissions from Reddit r/isthisai and r/isitai, X, and TikTok with zero false accusations on real photos.
Recompressed Web & Social JPEG
Evaluated through severe multi-hop lossy JPEG re-compression simulating Instagram, WhatsApp, and Reddit upload pipelines.
Cropped Mobile Screenshots
Processed via automated content-box boundary isolation, removing phone status bars and UI chrome while retaining full-frame micro-signatures.
Multi-Hop Resaved Files
Tested on files repeatedly resaved, forwarded, and re-encoded across multiple messaging and cloud storage platforms.
Hard Low-Resolution Stress Test
Evaluated on degraded sub-256px thumbnails and compressed image crops where spatial frequency cues are heavily constrained.

The Most Convenient Detection Extension
Never switch apps or copy links. Detect AI photos directly inside Photos, Safari, Instagram, TikTok, Reddit, and X with a single tap.
1-Tap Share Sheet Action Extension
Verify directly from Photos, Safari, Instagram, TikTok, Reddit, and X without switching apps.
Unlike traditional AI detectors that force you to take screenshots, leave your social feed, and upload files to a website, Is This AI? operates right inside your operating system's native Share Sheet. Tap 'Share' on any image, video, or post, select 'Check with Is This AI?', and get an instant forensic verdict sheet sliding up immediately.
Transparent evidence, not just a black-box percentage
Inspect Google SynthID watermarks, C2PA Content Credentials, and camera optical sensor noise.
Generic detectors spit out an arbitrary score with zero explanation. Is This AI? dissects the forensic anatomy of every image across multiple independent layers: proprietary 25-bucket ViT-S/16 neural classifier predictions, cryptographic C2PA provenance tags, Google SynthID imperceptible watermarking, and camera PRNU sensor noise variance.
Isolate faces, hands, and suspect objects in crowded posts
Pinch, zoom, and frame specific regions before running forensic analysis.
When evaluating a group portrait, viral meme with heavy captions, or composite marketing visual, social compression and overlay text can distort overall scores. Our built-in precision crop tool lets you isolate the exact face, background texture, or hands to run targeted neural forensics with maximum accuracy.
Warn friends and followers with verifiable proof
Export high-resolution 9:16 Story and 1:1 Post verdict cards in one tap.
Stop the spread of deceptive AI fakes before they go viral. Whenever you verify an image, export an authentic tamper-evident forensic verdict card styled for Instagram Stories, TikTok, X, or WhatsApp group chats. Choose between Dark Cinema and Light Paper aesthetic themes with detailed score breakdowns.
Track your scans and train your visual intuition
Browse past checks, review AI vs Real indicators, and wipe history anytime.
Every image you analyze is cataloged strictly inside your phone's encrypted local sandbox. Revisit past AI, Real, and Unclear verdicts to build your own visual intuition for spotting synthetic artifacts. Your scan history never syncs to third-party cloud servers and can be wiped with a single tap.

Frequently asked questions
How does this AI image detector know if an image is real or AI?
Our detector inspects visual patterns and invisible markers that generative tools leave behind. It checks for AI generation tags, camera lens characteristics, and synthetic textures to provide a clear, reliable verdict in seconds.
Can I use the detector for free without signing up?
Yes. You can test images directly online with zero sign-up required, or download the app on iOS and Android with 10 free scans included. No account or email is needed.
How do I check an image from social media without leaving the app?
On your phone, tap 'Share' on any photo or post in Instagram, TikTok, Reddit, X, or Safari, and select 'Check with Is This AI?'. An instant verdict slides up over your screen without needing to switch apps or copy links.
What should I do if an image is small, blurry, or cropped weirdly?
Use our built-in crop and zoom tool to focus directly on key subjects like faces or hands. Framing the main subject removes distracting text, meme borders, and social media watermarks for much cleaner results.
Are my personal photos saved, uploaded to public servers, or used for AI training?
Never. Your images are analyzed strictly in temporary memory and deleted immediately once your result is shown. We never store your photos on our servers or use them to train any AI models.
What does it mean when a result comes back as Unclear?
When an image is extremely compressed, heavily re-saved, or very low resolution, fine details can get lost. Rather than guessing or giving you a misleading answer, we flag it as Unclear so you know to check a higher-quality version.
What should I do if I think a detection verdict was wrong?
You can tap 'Was This Wrong?' right inside the app to submit feedback in one tap. Community reports help our team review difficult edge cases and continuously protect everyone against new types of AI fakes.
