AI that sounds like you
Answer a few questions. Get a tone profile you can drop into any Claude project.
How it works
Three steps. No prompting experience required.
Answer 6 situational prompts in your own words
We give you real situations — a quick reply to a colleague, an explanation for a friend, a cold pitch to a stranger. You write naturally. No right or wrong answers.
We analyze your vocabulary, rhythm, and voice patterns
The analysis looks at how you structure sentences, how formal or casual you run, which words you reach for, how much you hedge — the small things that make writing sound like a person.
You get a ready-to-use tone profile for Claude
A compact block of text you paste into a Claude project's system prompt. From that point on, Claude writes in your voice.
What you get
A compact system prompt block — plain text, a few hundred words — that captures the way you communicate. Paste it once into any Claude project and it holds.
Formality level
How formal or casual you tend to write, and when you shift between the two.
Sentence structure
Short and punchy, longer and considered — or a particular mix of both.
Word choices
The vocabulary you actually use, not generic AI vocabulary.
Tone
Dry, warm, direct, measured — whatever's true to you.
Works in Claude Projects, custom GPTs, or any AI system that accepts a system prompt.
