Every writer
has a voice.
What's yours?
Answer personalized questions about how you write, share samples of your work, and we'll build a codex that lets AI write like you — not a robot.
Gather Your Writing
Before you start, pull together 3–5 samples of your real writing — emails, blog posts, social captions, anything that sounds like you. The more variety, the sharper your codex.
The Interview
You’ll answer questions about your style, tone, and instincts — by voice or keyboard. Set aside about 30 minutes. The more thoughtful your answers, the better the result.
Use Your Codex
You’ll get a detailed voice profile to download or copy. Paste it into Claude’s Projects, a Custom GPT, Gemini — any AI tool’s instructions. Now it writes like you, not a robot.
What's a voice codex?
A detailed document that captures your writing patterns, tone, and style — so any AI can write like you.
