Lucen is an AI text-analyzer built for the dating and "talking" stage—paste in a thread from any chat app and it scores interest, flags ghost-risk, and decodes mixed signals. Attune is for the relationship you're actually building: it tunes what you say, unpacks what your partner meant, and layers in attachment science and the Gottman method.
If you're decoding a new match's mixed signals across WhatsApp, Instagram, or iMessage, Lucen is purpose-built for exactly that. If you're in a relationship and want to communicate better—attachment-tuned messages, Gottman conflict tools, and analysis of your real history—Attune goes deeper on the relationship itself.
