isitai

isitai is a web application for extracting and presenting image metadata (EXIF, C2PA, XMP, IPTC-IIM) from raster images (JPEG, PNG, HEIC, WebP). It helps verify the authenticity and provenance of digital assets by revealing embedded metadata.

Introduction

isitai specializes in extracting and presenting encoded metadata from raster images. The tool enables users to inspect embedded information such as device model, creation and modification dates, GPS coordinates, color profiles, and rendering intent. In an era of AI-generated and synthetic media, understanding an image’s provenance is crucial for trust and transparency.

Technical introduction

Frontend: Next.js with Chakra UI for a responsive, accessible interface.

Backend: Node.js (or serverless functions) for image processing and metadata extraction.

Features

• Extract EXIF metadata (camera information, timestamps, geolocation)
• Parse C2PA content credentials for cryptographically verifiable provenance
• Support for JPEG, PNG, HEIC, WebP and other common image formats
• Client-side processing; no files are uploaded or stored
• Simple and accessible UI powered by Next.js and Chakra UI

Example: EXIF metadata

Run the exiftool CLI on an example image:

exiftool img_0001.png

exiftool version number         : 13.25
file name                       : img_0001.png
directory                       : .
file size                       : 11 mb
file modification date/time     : 2025:05:10 21:14:04-05:00
file access date/time           : 2025:05:14 16:22:21-05:00
file type                       : png
mime type                       : image/png
image width                     : 4032
image height                    : 3024
bit depth                       : 8
color type                      : rgb
make                            : apple
camera model name               : iphone x
orientation                     : horizontal (normal)

Privacy & Security

• All files are processed locally in your browser; nothing is uploaded to any server.
• No data is collected, stored, sold, or used to train AI models.
• No advertisements.

Getting Started

For installation, development, deployment instructions, and detailed documentation, see the docs/README.md file.

Environment Variables

• Stripe keys: set secrets via environment variables; do not commit them to git.
• Local development: create .env.local in the project root with:

STRIPE_SECRET_KEY=sk_live_your_new_key
STRIPE_WEBHOOK_SECRET=whsec_your_new_secret

• Vercel: Project → Settings → Environment Variables

  • Add STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET for Production/Preview/Development, then redeploy.

• GitHub Actions: Settings → Secrets and variables → Actions

  • Add STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET as repository secrets if CI needs them.

• Key rotation: If a key is ever committed or exposed, rotate it in the Stripe Dashboard (Developers → API keys), then update the environment variables accordingly.
