About RimeTime

A rhyme finder and thesaurus for songwriters and poets.

RimeTime finds rhymes the way a songwriter's ear does — grouped by how close the sound actually is, not just a flat list. A search returns up to six tiers: Perfect (identical from the stressed vowel on), Near (same vowel and syllable count, with a swapped consonant that still sounds right — like D/T or M/N), Slant (matches over more than one syllable), Assonance (vowel match only), Consonance (final consonants match), and Loose (just the very last sound) — strictest tier first, so the pairs a rhymer would reach for first are always on top.

The Thesaurus panel shares the same dictionary lookup: definitions grouped by part of speech, plus synonyms and antonyms where the dictionary has them.
