Use the new Freestyle drafter to get inspiration as you think out loud. Suggestions are automatically offered for the bit you seem to be working on. Our AI philosophy in a letter A note to your other lyrics app: AI can't write lyrics. So many new songwriting apps don’t get this. AI just writes the song, and the output is derivative by design. Great art is a product of emotion and experience by the unconscious mind, not a rehash of unlicensed pop songs spewed by autocomplete matrix math in a data center on leveled farmland. Expediting the process while undermining the authenticity is futile. Lyrium is fundamentally different. It’s built from the ground up to cultivate connections and inspiration in *you*. We tap the best tools available to amplify your sparks at every songwriting stage: a powerful rhyme dictionary and Roget-style thesaurus, your sense memories, your journal, and creative interfaces that tap language models for their mastery of language, not lyrics. All this input is tied together in a first-of-its-kind workspace that exposes the power and flexibility you’d expect from the pro tools you use to make the rest of your music.
