Duplyfi

I'm the founder of Duplyfi (https://duplyfi.com), a desktop application for batch video and image uniquification. Duplyfi takes one source file and outputs hundreds of unique, metadata-clean variations, processed locally on your own machine — no uploads. It's built for operators running multiple accounts who post the same content across many platforms and need every copy to be file-level unique. Duplyfi runs on Windows, macOS, and Linux, with a full-featured free trial. Try it at https://duplyfi.com
