Convert between US Title Case (AP, Chicago) and UK Sentence Case (Gov.uk) with linguistic accuracy. Privacy-first, client-side processing.
Most text tools blindly apply American title case rules. But British publications like the BBC and The Guardian use sentence case—a fundamentally different standard.
British English sentence case
"The prime minister announces new climate policies for the UK"
Only the first word and proper nouns capitalised
American English title case
"The Prime Minister Announces New Climate Policies for the UK"
Major words capitalised per AP/Chicago style
Existing tools were built for American audiences and fail to recognise British English conventions. International copywriters working with British clients need accurate sentence case conversion—not approximations or manual corrections.
CorrectCase is the first tool built from the ground up to handle both standards correctly, with awareness of British grammar, hyphenation rules, and SI unit formatting.
