CompareExperts is a free suite of forensic analysis and comparison tools built for security researchers, journalists, educators, and curious people who want to see what's really inside their files, text, and websites.
Our Mission
We believe powerful forensic tools should be accessible to everyone — not locked behind enterprise paywalls or desktop software. Every tool on CompareExperts runs entirely in your browser. Your files, images, and text are never uploaded to our servers. Zero. None. Nothing leaves your device.
What Makes Us Different
⚔️
Compare Mode on Every Tool
Every tool supports side-by-side comparison. Compare two images for manipulation differences, two passwords for strength, two domains for security posture.
🔒
100% Client-Side Processing
All analysis uses Web APIs — Canvas, Web Crypto, WebGL, TextDecoder. Your data never touches a server.
🧬
Real Forensic Techniques
ELA (Error Level Analysis), DCT frequency domain AI detection, Shannon entropy, magic byte detection, homoglyph scanning — techniques used by real-world investigators.
⚡
AI-Powered Analysis
For tools that benefit from deeper reasoning, we optionally run Llama Vision and Llama 3.3 70B models via a server-side API — always opt-in, never automatic.
