The words carry your meaning. The way you say them carries your voice. Speak for a minute or two about a subject you are passionate about, and VoiceBook listens the way a ghostwriter would, for your rhythm, your energy, your music.
Tap Speak and talk. Your words appear below and stay held.
Step 2 of 5 — The spices
What you love, hate, watch, and learn from
These are hypotheses. VoiceBook confirms or rejects each one against how you actually sound, so your fingerprint is grounded in you, not in who you admire.
Step 3 of 5 — Your own writing
Upload anything you have already written
Your own writing is hard evidence of your real voice, weighted alongside your interview. If you have a book already in progress, Voice Book Writer continues it in your established voice, not from zero. Accepts PDF, Word (.docx), Excel (.xlsx), and plain text. Apple Pages files are not readable in their native format; export from Pages (File > Export To > Word or PDF) and upload that instead, it takes seconds.
Step 4 of 5 — What we found
This is what we heard, read, and researched
Five layers, grounded in your own speech and writing. Notice what was confirmed and what was rejected, that is the honesty other tools skip.
Step 5 of 5 — The honest test
Which one is you?
Two samples on your topic. One is written in your voice. One is generic AI. They are unlabeled and the order is random. If your fingerprint is real, you will feel which one is yours. Pick it.
Read both. Click the one that sounds like you.
