The problem
By default, Claude sounds like... Claude. Competent, clear, and completely generic. That's not because AI is bad at writing — it's because Claude doesn't know you. Without knowing your voice, it defaults to something that works for everyone, which means it sounds like no one.
The fix is a Voice Profile: a block of text you give Claude once that tells it exactly how you sound. After that, everything it writes for you will sound like you.
What you'll build — the Voice Profile
Build it in 5 steps
Collect your best writing
Find 3–5 pieces of your own writing that feel most like you. Instagram captions, emails, voice notes transcribed, text messages, stories. The ones where someone read it and said "that's so you." Don't overthink it — instinct is right here.
Ask Claude to analyze your voice
Paste your examples into a new Claude chat and use this exact prompt:
"Here are some examples of my writing. Read them carefully and describe my writing voice back to me — my tone, sentence length, vocabulary, what I seem to value, anything that makes my writing distinctly mine. Be specific."
Then read what Claude gives you. It'll catch things you didn't know were distinctly you.
Fill in your Voice Profile
Use the template below to build your profile. Copy the Claude analysis from Step 2 into the relevant sections — don't start from scratch.
Save it where you'll actually use it
Claude Projects (recommended): Paste your Voice Profile into your Project instructions. Claude will always have your voice — no pasting needed, ever again.
A note on your phone: Paste it at the top of any new chat when you're writing something important.
Test and refine
Ask Claude to write something short. Read it out loud. Does it sound like you? If not, add a line to your profile: "Never use the word [X]." "Always write in short punchy paragraphs." "I never start a sentence with 'I'." Your profile gets sharper every time you refine it.

Weak vs strong — see the difference
Scenario: writing an Instagram caption about feeling overwhelmed as a working mom.
WITHOUT voice profile
Feeling overwhelmed is a common experience for working moms. It's important to remember that you're doing an incredible job, and it's okay to ask for help. Take a moment today to acknowledge all that you've accomplished. You've got this! 💪 #workingmom #momlife #selfcare
WITH voice profile
3pm and I've answered 47 emails, forgotten to eat lunch, and said 'just a sec' to my kid four times. This is the part they don't put in the highlight reel. If this is you today — you're not failing. You're doing something genuinely hard. That's it. That's the post.
Pro moves (once you've got the basics)
Build voice variants
Your caption voice (punchy, short) vs your email voice (warmer) vs your story voice (vulnerable, narrative). Save them as separate Project instructions or note sections.
Add "I would never say..." examples
The more specific your "nevers" list, the sharper Claude gets. Real examples beat adjectives every time.
Update it as you evolve
Your voice changes. Every few months, rerun Step 2 with new writing samples and see what's shifted.
Your voice is your unfair advantage. AI can write the words — you bring the person behind them.
