Technology

Five layers of naturalization

Each image passes through our proprietary pipeline that makes AI artifacts mathematically indistinguishable from real camera output.

Sensor Simulation

Injects realistic camera artifacts — Bayer demosaic patterns, ISO grain, chromatic aberration, and natural vignetting.

Frequency Analysis

FFT-based smoothing identifies and removes the high-frequency mathematical signatures left by AI generators.

Diffusion Reconstruction

Pixel-level rewriting using Stable Diffusion that regenerates surface texture while preserving composition.

EXIF Injection

Generates realistic camera metadata — make, model, exposure, focal length — from real device profiles.

Batch Processing

Process up to 20 images at once. Queue management handles everything — just upload and wait.

REST API

Integrate PassReal into your workflow with our documented API. Full OpenAPI spec included.

FAQ

Common questions

Our pipeline maintains a SSIM score above 0.85 compared to the original — meaning the visual difference is imperceptible to the human eye. The output is a high-quality JPEG (93-96 quality) with realistic camera characteristics.

PassReal is tested against 12+ leading detectors including Hive Moderation, Illuminarty, AI or Not, GPTZero, SynthID, Sensity AI, and others. Our pipeline targets both pixel-level statistical analysis and invisible watermark detection.

Processing typically takes 20-60 seconds depending on image size and server load. You'll see real-time progress updates as your image passes through each pipeline stage.

Yes. Images are processed and then automatically deleted from our servers. Source images are removed immediately after processing (unless you opt to retain them), and results expire after 7 days. We never use your images for training.

PassReal is an image processing tool, similar to photo editors or filters. How you use the output is your responsibility. We recommend using PassReal ethically and in compliance with applicable laws and platform terms of service.
