Startup CEO

Board-level pivot message

The difference

Same prompt. Different voice.

First, what you get from AI out of the box. Then, what you get with a voice profile.

"Tell your board that you're pivoting the product strategy"

Voice profile: Startup CEO

Bottom line first, short sentences, specific deadlines. Uses "we need" not "you should." Ends every message with next steps. Formality 3/10.

Without MyDamnVoice

I'd be happy to help you prepare for that board conversation. Here's a framework for presenting a product strategy pivot: 1. Context & Rationale - What data/insights drove this decision? 2. The Pivot Details - Clear before/after comparison. 3. Resource Implications - Budget requirements and reallocation. Would you like me to help you develop any of these sections specifically?

With MyDamnVoice

We're pivoting. Current approach isn't delivering the growth metrics we need. Enterprise-first is burning cash faster than we're acquiring customers. Sales cycles are 8+ months, churn is 23%. New direction: self-serve with freemium. Engineering pivots Monday. Marketing shifts messaging by end of week. We execute or we're dead.

"Write an Instagram caption for a new product launch (vitamin C serum)"

Voice profile: Gen Z Social Media Manager

Lowercase, self-aware, culturally literate. Starts with "ok so" or "the thing is." Never sounds like corporate. Formality 2/10.

With MyDamnVoice

ok so i've been testing this vitamin C serum for like 3 months and honestly? my skin looks... good? which is weird bc i'm usually the person who buys skincare and then forgets to use it for weeks. also it doesn't pill up under makeup which is SHOCKING. sometimes the simplest things just work

"Start a D&D campaign with a rat, a dragon, and a pig saving a drowning fish"

Voice profile: D&D Dungeon Master

Cracks jokes at the table between epic moments. Mixes casual profanity with poetic structure. Drops "chungus" and "Sikeeeee" like breadcrumbs. Punchy controlled chaos. Formality 2/10.

Without MyDamnVoice

At the edge of a slow river, a fish struggles near the surface. It thrashes weakly, gills flaring, as if the water itself has turned against it. Three unlikely figures stand on the muddy bank watching the spectacle unfold. The rat notices the fish first. "That fish is drowning," he says. The pig leans forward, studying the scene with confusion. "How does a fish drown?" he asks.

With MyDamnVoice

Behold. The fish is already drowning. Not metaphor drowning. Actual flapping panic drowning. Little silver idiot gulping river water like it owes him money. And standing on the muddy bank are three heroes. Which is generous wording. A rat with one eye and six opinions. The pig squints at the river like the concept of water personally offended him. "How the fuck does a fish drown."

How it works

Five minutes. Three steps.

1

Tell us how you write

We ask how you write, what you like, what you can't stand. Takes about five minutes.

2

Show us the proof

Paste writing samples and we run real stylometric analysis: sentence length, word choice, punctuation habits, the patterns you wouldn't notice about your own writing. Where your stated preferences contradict your actual samples, the samples win.

The artifact

A prompt you paste directly into your AI. Here's a real example (redacted):

ChatGPT Custom Instructions

Voice DNA: Direct, bottom-line-first communicator. Short declarative sentences. Favors specificity over hedging. Contractions always.

Formality: 3/10 · Energy: 7/10 · Warmth: 5/10

Vocabulary: "ship it," "bottom line," "let's go" · Avoids: "leverage," "synergy," "circle back"

Sentence profile: Avg 11 words. Variance low. Rarely exceeds 20 words. No compound-complex.

Never: Start with "I'd be happy to" · Use em dashes · List more than 3 bullet points · Say "great question"

FAQ

Common questions.

Where do my writing samples go?

First we run stylometric analysis on your samples locally (sentence length, word choice, punctuation habits). Then we send them to Anthropic's Claude API to generate your profile. After that they're gone. Nothing is stored, nothing is used for training.

Does this work with ChatGPT, Claude, and Gemini?

Yes. The full profile gives you exports for ChatGPT Custom Instructions, Claude Styles, and Gemini Gems. Each one is formatted for that platform.

What's the difference between free and paid?

Free gives you a basic voice prompt you can paste anywhere. The $9 profile adds platform-specific exports, word choice analysis, and sentence pattern data from your actual writing samples.

Can I update my profile later?

Yes, within the same browser session. Your purchase includes a few regenerations so you can tweak your answers and re-run the interview. If you close the tab, you'd need to take the interview again.

What if I'm not happy?

Email support@mydamnvoice.com and we'll help you out. If your profile doesn't sound right, we can work with you to fix it.

Do I need an account?

No. Everything runs in your browser. No sign-up, no account.

Your voice is worth five minutes.

After this, every AI you use sounds like you wrote it yourself.

Free prompt included. Full profile $9, once.
