About this tool
The whole text is lowercased first. Then the first letter of the text, and the first letter after each . ! ? or ؟, is capitalized. Because everything else is lowercased, names, acronyms, and the pronoun "I" also lose their capitals and need fixing by hand.
How to use it
- Paste the text you want to fix.
- Copy the sentence-case result.
- Restore capitals on names and acronyms.
After . ! ? capitalize the next letter
Examples
All caps
"THIS IS URGENT. PLEASE REPLY." becomes "This is urgent. Please reply."
Proper nouns
"we met ANNA in PARIS." becomes "We met anna in paris.", so the names need capitals again.
FAQ
Why did names become lowercase?
The converter cannot tell names from ordinary words, so it lowercases everything except sentence starts.
Does it capitalize after line breaks?
Only if the previous line ended with . ! ? or ؟. A line with no ending punctuation continues the same sentence.
