Ever wondered how ColdCheck makes messages that sound like you? This guide explains the magic behind voice matching and why it works.
A Voice Fingerprint is how we analyze your writing to understand your unique communication style. It's not just about copying phrases, it's about capturing the essence of how you express yourself.
When you add writing samples, ColdCheck looks at several dimensions of your voice:
How formal or casual you are
Do you use contractions? (you're vs. you are)
Do you start sentences with "And" or "But"?
How often do you use casual expressions?
Your level of warmth
Do you use friendly phrases like "Hope you're doing well"?
Do you include personal touches or stay strictly professional?
How do you balance friendliness with professionalism?
Sentence length
Do you write short, punchy sentences?
Or longer, more detailed explanations?
Do you vary your rhythm?
Paragraph style
Single-sentence paragraphs or longer blocks?
How you break up ideas
Use of bullet points or lists
Vocabulary level
Simple, clear language vs. more sophisticated terms
Industry jargon you naturally use
Technical vs. accessible explanations
Signature phrases
Words and expressions you favor
How you transition between ideas
Your go-to ways of explaining things
Enthusiasm level
Use of exclamation points
Energetic language vs. understated tone
How you express excitement or concern
Directness
How quickly you get to the point
Use of softening language ("maybe," "perhaps")
How you make requests or suggestions
Humor and personality
Whether you include light humor
Personal anecdotes or stories
Professional but personable touches
Here's what happens behind the scenes:
ColdCheck analyzes your samples to identify patterns in how you write. We're looking for consistency; the things you do across multiple messages that define your style.
We create a unique profile that captures:
Your tonal range (formal to casual)
Your structural preferences
Your vocabulary patterns
Your personality indicators
When you create a message, ColdCheck:
Reads your intent
Applies your voice profile
Generates text that matches both your intent and your style
Adjusts for the format (email vs. LinkedIn)
We ensure the output:
Sounds natural, not robotic
Stays true to your voice
Matches the context appropriately
Flows the way you write
The key is authenticity. We don't:
Use generic templates
Copy-paste phrases from your samples
Apply a one-size-fits-all "professional" tone
Instead, we:
Learn your unique patterns
Generate new text in your style
Adapt to different contexts while staying true to your voice
Balance consistency with natural variation
Your voice isn't static; it can improve over time:
The more samples you provide:
The more nuanced your voice profile becomes
The better we understand your range
The more contexts we can handle
Adding variety helps:
Formal emails teach us your professional voice
Casual messages show your approachable side
Different topics reveal how you adapt
Let's clear up some misconceptions:
It's not copying
We don't take sentences from your samples and reuse them
We generate entirely new text based on your style
It's not a template
Every message is unique and contextual
We adapt to what you're trying to say
It's not perfect mind-reading
We match your style, but you might still want to edit
The goal is to get you 90% there, not 100% hands-off
When the Voice Fingerprint works well, you should think:
"I could have written this"
"This sounds natural, not robotic"
"This captures my tone"
You shouldn't think:
"This sounds too formal for me"
"I would never phrase it this way"
"This doesn't feel like my voice"
