Frequently asked questions

What's the difference between Title Case and Capitalized Case?

Title Case follows headline style: small words like 'a', 'of', 'the' and 'to' stay lowercase unless they're first or last. Capitalized Case capitalises every word.

I typed with Caps Lock on by mistake — can I fix it?

Yes. Paste the text and choose Sentence case: everything becomes lowercase with a capital at the start of each sentence.

What are camelCase and snake_case for?

They're used for names in programming and file names: camelCase joins words with capitals (myFileName), snake_case uses underscores (my_file_name), kebab-case uses hyphens (my-file-name).

Does it work with Hindi or Punjabi?

Indian scripts don't have capital letters, so those words stay as they are — English words in the same text still change.
