Show HN: Cupitor – Text Replacement Tool (cupitor-26c026.gitlab.io)

Hi! I've been working on a text replacement tool that allows users to upload a text file, identify and replace duplicate words, and then copy the modified text into clipboard. The tool is built using plain JavaScript and utilizes a simplest interface. What it does is basically multiple word replacements that is done in text editors via "Ctrl + r" shortcut.
