Two files in.
One clear answer out.
Contracts, configs, workbooks, screenshots — Diffesq shows exactly what changed, without your files ever leaving the machine.

How it stays private
Runs in your browser
Parsing, diffing, and rendering all happen locally — turn off Wi-Fi and it still works.
No account, no upload
There is no server to send files to and nothing to sign up for. Drop, read, done.
Reports made locally
Exports — HTML, Markdown, JSON, PDF — are generated on your device, watermark-free with Pro.
Folders and image libraries, too.
Point Diffesq at two directory trees and review every difference in one pass — or scan a photo library for duplicates it finds by looking, not hashing.
Every format, its own view
15 file types. One comparison that fits each.
Drop two files and Diffesq detects the format, then opens the right view — a document redline, a spreadsheet grid, a semantic data diff, a slide-by-slide deck, or a page-by-page PDF. All of it runs on your device.
