Redcast Dictionary
Define words using the dictionaries already enabled on your Mac.
Run Define Word, or choose its fallback under a launcher query. The dictionary screen keeps your term in the search field so you can look up another word without reopening it.
Choose your dictionaries
Redcast reads the dictionaries enabled in Dictionary.app. Enable and order the languages or dictionaries there. The first enabled dictionary with a match supplies the entry; Redcast does not download a separate word list or send a lookup to a search provider.
Read and copy
Return copies the displayed definition and closes the palette. ⌘Return opens the term in Dictionary.app, where you can inspect other enabled dictionaries.
If the term has no match, check spelling and try it in Dictionary.app. A missing or disabled language dictionary cannot be supplied by Redcast itself.
Command and fallback
The command is managed in Settings → Commands. Hiding it also removes its fallback. The fallback's own switch only controls the fallback row, leaving the command available by name when its command is enabled.
For online research or a word missing from the local dictionaries, use an explicitly configured quicklink or AI web search.
