Your files never leave your device. Ever.

Compare Files works entirely in your browser. There is no server that receives, processes, or stores your file data. Not because we promise not to look — but because we architecturally cannot. All comparison logic runs locally in JavaScript.

Why no AI

No AI means no hallucinations.

Compare Files uses a deterministic, logic-based engine — not a language model. It reads both files and reports every change that is actually there. It can’t summarize away a deleted line, invent a difference that isn’t in the file, or “mostly” get a number right. What you see is exactly what changed — nothing added, nothing missed.

Private

Your files never leave your device. Everything runs in your browser — no uploads, nothing stored.

Certain

No AI, so no hallucinations. A deterministic engine reports every real change and never invents one.

Fast

No upload, no server wait. Comparisons run locally and keep working offline once the page has loaded.
