AI That Learns to Sound Like You

Lumina's voice learning analyzes your existing content across 9 dimensions: tone, formality, confidence level, sentence structure, vocabulary range, personality markers, hook style, call-to-action patterns, and industry context. By processing multiple samples of your writing, we build a unique voice profile that captures your authentic style.

Any writing that represents your authentic voice works: past LinkedIn posts, blog articles, newsletter content, presentations, emails (especially ones you've polished), internal documents, even thoughtful Slack messages. The more diverse samples, the better Lumina captures your range.
