Analyze likely casing without changing the source. Heuristic labels are descriptions, not linguistic guarantees.
Analysis runs only in this browser.
Input size: 0 B.
Empty input
Enter text to analyze its casing.
The checker distinguishes empty input, content with no cased letters, uncased-script text, uppercase, lowercase, title-like, sentence-like, and mixed case.
Title-like and sentence-like are transparent heuristics rather than claims about linguistic correctness. Processing remains browser-local.
Using this tool
Inspect the current text to see which case patterns it contains.
Example: `HELLO`, `hello`, and `Hello` are reported as different case patterns.
The checker analyzes text without replacing it, so it is useful before choosing a conversion.
Mixed-case names and acronyms can be intentional and are not treated as errors.
Conversion is performed in the browser. Copying or downloading happens only when you choose those actions.
