It finds all dictionary words that are anagrams of the word you enter, meaning words made from exactly the same letters rearranged.
It compares the sorted letters of your word against a dictionary of known words, and any word sharing the identical sorted-letter pattern and length is returned as a match.
The tool shows a message stating that no anagrams were found for your word.
No, this tool requires a single word using letters only, and it will show an error message if you enter spaces or numbers.
It searches against its own dictionary word list, so results depend on which words are included in that list rather than an exhaustive dictionary of every English word.
