CollisionLab is a free metaphor generator for songwriters and poets. Type a topic, grief, light, the sea, a Tuesday, and the tool returns concrete sensory images, conceptual collisions, and unexpected pairings designed to break you out of literal language. The point is not to use the output verbatim. The point is to find the shape of a metaphor your conscious mind would not have reached for.
The mechanic is friction. Two ideas from unlike domains, smashed together, generate the kind of image that lives in great lyrics: a memory described as something physical, an emotion described as a place, a relationship described as weather.
CollisionLab works best paired with RhymeForge for the words around the image, and the chord progression builder for the music underneath.
Part of the Undercover Zest songwriting suite. No account, no cost, no catch.
