✨ Features

🔍 Deep C2PA Manifest Parsing

Images from ChatGPT, DALL-E, Adobe Firefly, and other C2PA-compliant tools embed a signed manifest. mtsb info extracts and displays:

• Software agent (e.g. gpt-image → "ChatGPT (OpenAI)")
• Claim generator (e.g. OpenAI Media Service API)
• Actions (created, converted, watermarked)
• Timestamps, certificates, signatures, and more

🎯 Accurate AI Tool Detection

Tool	Detected As
ChatGPT / DALL-E	ChatGPT (OpenAI)
Midjourney	Midjourney
Stable Diffusion (A1111)	Stable Diffusion (A1111)
ComfyUI	ComfyUI
Adobe Firefly	Adobe Firefly
Canva	Not AI — treated as human editing app

🛠️ Data Manipulation

• Auto Organic — Random realistic camera profile (Canon, Nikon, Sony, Fujifilm, etc.) with matching shooting settings
• Custom Edit — Manually type every EXIF field: make, model, lens, ISO, aperture, shutter speed, GPS, description, artist, copyright
• Design App — Inject metadata mimicking Photoshop, Procreate, Clip Studio Paint, Krita, GIMP, Canva, etc.

🖼️ Supported Formats

Format	Details
PNG	C2PA, text chunks, and EXIF
JPEG / JPG	Full EXIF + XMP metadata
WebP	Metadata support
