How does ContentDNA analyze my writing voice?

ContentDNA uses AI to analyze the specific patterns in your writing: sentence length distribution, how you open and close posts, the vocabulary you use, your emotional register, and unique quirks like how often you ask questions or use lists. This creates a precise voice fingerprint that can be used to generate new content.

Can ContentDNA write content that sounds exactly like me?

Yes. Unlike generic AI tools, ContentDNA extracts your specific writing DNA — not just 'your tone' but exact patterns: your hook style, power words you actually use, your sentence rhythm. It generates content that captures these specific traits, not just a generic approximation.

What types of content can ContentDNA generate?

ContentDNA can generate tweets (under 280 characters), LinkedIn posts, email introductions, and newsletter sections — all in your analyzed writing voice. You can also compare the output against what a generic AI would write.

How is ContentDNA different from ChatGPT for writing?

ChatGPT generates generic content based on a prompt. ContentDNA first analyzes your actual writing to extract a voice fingerprint — sentence patterns, vocabulary, hooks, closings — then uses that fingerprint to generate content. It also improves with each use as you rate outputs, building a model specific to you.

Is ContentDNA free to use?

ContentDNA offers 3 free DNA analyses. Paid plans start at €29/month (Starter) for unlimited analyses and generations, and €69/month (Pro) for advanced features including voice consistency tracking and shareable DNA profiles.
