Author Voice DNA extraction and profile generation

★ 6.5 · marketing

voice-dna is a Claude Code skill that extracts authentic voice patterns from writing samples using a 5-layer analysis system and generates a custom AI prompt for accurate voice replication. The five layers cover structural DNA (sentence construction, punctuation), linguistic DNA (word choices, signature phrases), tonal DNA (emotional register, humor style), narrative DNA (story patterns, metaphors), and ideological DNA (core beliefs, values, vulnerability level). It requires 10–50 samples totaling 5,000+ words — emails, Twitter/X and LinkedIn posts, blog articles, podcast and video transcripts — and identifies patterns appearing in 60% or more of the material, including what the author conspicuously avoids. Output is a complete Voice DNA Profile document and a ready-to-use replication prompt saved to the project directory. Built for content marketers, brand builders, and creators who want to scale AI-assisted content production without losing a distinctive, recognizable voice.
