Case converter for writing and naming
Turn one phrase into many naming styles quickly with a local conversion utility. Great for content owners, developers, and designers who need consistent case formats.
This is the free version
Works where you write
PromptDC rewrites selected text in any app, every browser, your IDE and your terminal on Mac and Windows.
One keyboard shortcut
Select text, press Cmd+Shift+E or Ctrl+Shift+E, review the result, then Replace or Copy. It never presses Enter for you.
Your profiles, your models
Pick a default profile per app, or bring your own API key on the Lifetime plan.
Free here: unlimited, this utility runs entirely in your browser. In the app: from $9/mo, or Lifetime from $69 with your own API key.
The case converter handles UPPER, lower, Title, Sentence, camelCase, snake_case, and kebab-case output from one input text. This saves manual edits and avoids missing a style standard when moving between UI labels, code artifacts, and docs. Because it is fully client-side, your content remains local and the conversion is instant.
