RHYME FINDER

Works with a plain word list (.txt, one word per line) or an actual national/print dictionary PDF, headword + definition and all — search for "[language] dictionary PDF" and most results will work. Definitions get pulled in automatically when the file follows a standard dictionary layout; if not, you still get every word for rhyme matching. It usually finishes importing faster than the PDF would open on your phone.

Matches are found by comparing the last few letters of each word — a phonetic approximation, not a true dictionary. Multi-word phrases match on their final word.
