# IA ou Não

> IA ou Não is a Brazilian-made AI content detection platform. It uses forensic analysis techniques — EXIF metadata extraction, Error Level Analysis (ELA), digital noise patterns, and 60+ AI tool signatures — to determine whether images, videos, or text were generated by artificial intelligence. The platform is free for basic analysis and offers a premium forensic tier with GAN/Diffusion pattern detection. All uploaded files are processed in-memory and automatically deleted — no data is stored.

## Main Tool

- [AI Content Detector](https://iaounao.com/): Upload an image (PNG, JPG, WEBP), video (MP4, MOV), or text to detect if it was generated by AI. Free basic analysis with forensic upgrade available.

## How It Works

- [Detection Pipeline](https://iaounao.com/#como-funciona): 4-step forensic process — Upload → Multi-tool Analysis → Score & Verdict → PDF Report. All processing under 10 seconds with immediate file deletion.

## Forensic Tools

- [EXIF/XMP Metadata Analysis](https://iaounao.com/#ferramentas): Extracts camera data, GPS, timestamps, and software markers from 60+ AI generation tools including DALL-E, Midjourney, Stable Diffusion, and Flux.
- [Error Level Analysis (ELA)](https://iaounao.com/#ferramentas): Detects JPEG compression inconsistencies, digital noise uniformity, gradients, and absence of sensor noise across 5 verification layers.
- [Pixel & Texture Analysis](https://iaounao.com/#ferramentas): Color histogram, Laplacian edge detection, local entropy, GLCM, and saturation analysis. Identifies synthetic textures invisible to the human eye.
- [AI Tool Signatures](https://iaounao.com/#ferramentas): Updated database of digital fingerprints from DALL-E, Midjourney, Stable Diffusion, Flux, Adobe Firefly, and dozens of other AI generation tools.

## Pricing
