Frequently asked questions

How are word boundaries detected?

The converter splits on spaces and separators (_ - . /) and on camelCase boundaries, so getHTTPResponse and get_http_response both tokenize the same way.

Is my text sent anywhere?

No. All conversions happen locally in your browser with JavaScript.

Does it handle acronyms?

Runs of capitals (e.g. API, HTTP) are treated as a single token, so they convert cleanly into other cases.
