About Smoke Det
Smoke Det is a free, browser-based utility designed to make this task as quick and frictionless as possible. Everything happens client-side, which means your files and data never leave your machine. The interface is intentionally minimal so you can focus on the task instead of learning the tool. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
