Voice Profile Builder
Every AI writes in a generic voice until you tell it not to. This tool walks you through a few quick choices, then hands you a voice profile you can paste into ChatGPT, Claude, or any AI so it writes the way you do.
- Answer a few short questions. Takes about two minutes.
- Get a clean markdown file built to guide any AI.
- Paste it in, or save it and reuse it whenever you write.
Free. No signup. Everything runs in your browser, so nothing you type is sent anywhere.
Name your voice
Give this profile a name so you can find it later. The rest is optional, so skip anything that does not matter to you.
One line of context. This shows up at the top of your file.
The feel
How should it sound, and how easy should it be to read?
Pick the one that fits best. Tap it again to clear it.
The shape
How is a typical piece put together?
How the writing tends to be organized. Optional.
If you follow a specific copy style guide, name it.
Length
How lean or how full should the writing be? Drag the slider to see what each setting means.
Greetings & phrasing
The small habits that make writing sound like a person.
Which openings are allowed? Pick any. Leave all off for no preference.
How should it address the reader?
Short forms like TBD and WFH, or spell everything out?
Write the way people talk ("Would be great to connect"), or use full sentences?
Your words
A few traits and real examples teach the AI more than any setting.
Short words that describe the voice. Type one and press Enter.
Or tap to add:
Paste one or two lines you have actually written in this voice, one per line. The AI matches their rhythm.
Rules & extras
Hard rules are things the AI must never do. The rest is optional.
Words, clichés, or punctuation to ban. Type one and press Enter.
Common ones, tap to add:
A go-to way you like to open. The AI adapts it, never copies it word for word.
How you like to ask for the next step.
Your voice profile
Here is your profile. Copy it or download it, then hand it to your AI.
This is plain markdown. It works in any AI chat. Edit it any time by going back through the steps.
How to use it
- Open a new chat in ChatGPT, Claude, or any AI you like.
- Paste this profile as your first message, or add it to the system prompt or custom instructions.
- Then ask for what you need. The AI will write in your voice.
It sets how you write, not what you write
One voice, every tool
Build it once. Use it in any AI, on any day. No more re-explaining how you like to sound.
Form, not facts
A voice profile guides tone, length, and rules. It never makes up claims or facts. The substance still comes from you.
