NEW: My Writing Voice, AI That Sounds Like You

Most AI writing tools ignore your personal style entirely, or try to cram style instructions into an already overloaded prompt. The result? Every book sounds like it was written by the same generic AI.

SidekickWriter takes a fundamentally different approach with a dedicated two-pass architecture:

  • Pass 1, Content Generation: The AI focuses entirely on plot, characters, structure, and story with zero style distraction.
  • Pass 2, Voice Matching: A completely separate AI pass rewrites each chapter with one single job, match your writing voice. Your sentence rhythm, vocabulary, tone, pacing, dialogue patterns, and descriptive style get 100% of the AI's undivided attention.

Because the voice-matching pass has no competing instructions, the AI dedicates its full context window and attention budget to sounding like you. The difference between single-pass style injection and this dedicated rewrite is dramatic.

How to use it:

  1. Save 1,000+ words of your own writing to your reusable Voice Library
  2. Let the AI analyze your sample into a detailed style profile
  3. Generate your book normally, then apply your voice to individual chapters or the entire book
  4. Every plot point, event, and dialogue beat stays intact, only the voice changes
