About this tool

Fix capitalization in one click

Case conversion is useful when pasted text arrives in all caps, headings need consistent title case, or identifiers need camel case. The converted text stays editable, so you can review names, acronyms, and specialized terms before copying it.

Automatic title and sentence case are practical starting points, not editorial judgment. Proper nouns, brand spellings, scientific names, and style-guide exceptions may still need manual correction.
