Does my data get uploaded anywhere?
No. Everything runs locally in your browser and nothing is sent to a server.
Is this free to use?
Yes. It is completely free, with no account, no signup, and no usage limits.
Do I need to install anything?
No. The tool runs entirely in the browser, so there is nothing to download or install.
Why is "iPhone" coming out as "IPhone"?
The tool uppercases the first letter and leaves everything after it untouched. It has no list of brand names, so any word with a deliberate internal capital or a lowercase first letter will be changed. Fix those few words by hand afterwards.
Can I use this for a headline in AP or Chicago style?
Not without editing. Both style guides keep short conjunctions, articles, and prepositions lowercase unless they open or close the title, and this tool capitalises them all. Use it as a starting point and lowercase the small words yourself.
How do I fix text that is in ALL CAPS?
This tool alone will not help, because it leaves the trailing letters as they are and your text will stay in caps. Lowercase the text first in your editor, or run it through the Sentence Case Converter and then capitalise the words you need.
What happens to hyphenated words?
Each part is treated as a separate word, so "state-of-the-art" becomes "State-Of-The-Art". That is usually not what you want in running text, so review any hyphenated compounds in the output.
Does it work with accented and non-English text?
Partly. It recognises letters from any script, but the word-boundary rule behind it is ASCII-based, so a word that starts with an accented letter can end up with the wrong letter capitalised. Check non-English input by eye rather than trusting the result.
