Questions
Does this preserve line order?
Yes by default. The first occurrence of each line is kept, and you can enable Sort A-Z when you want alphabetized unique output.
Can it ignore capitalization?
Yes. Enable ignore case to treat Apple, apple, and APPLE as the same line.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
