Questions
›Is the comparison case-sensitive?
By default yes. Turn on "ignore case" to treat "Apple" and "apple" as duplicates.
›Is my data uploaded anywhere?
No. This tool runs entirely in your browser, and Rounder never sends what you type or drop in to a server, ours or anyone else's. Once the page has loaded, along with any AI model the tool uses, it even works offline.
