Discover Your Voice
Before you can teach Claude anything, you need to know what you're teaching. Your voice isn't just your word choices — it's your rhythm, your warmth, your perspective. It's the thing your audience recognizes even without seeing your name. This section helps you uncover it.
What is "voice," really?
Think of voice as the sum of three things: what you say (your topics and opinions), how you say it (your tone, pace, sentence length), and who you're saying it to (the relationship you have with your reader). Claude can learn all three — but only if you can name them first.
Reflection Prompt 1 — Your reader relationship
Paste this into Claude to start articulating your tone. The output becomes raw material for your voice guide.
I want to understand my writing voice better so I can train an AI to write like me. Please help me reflect by asking me five questions — one at a time — about how I talk to my audience, the words I naturally avoid, and the feeling I want people to walk away with after reading my content. After I answer all five, summarize what you've learned about my voice in a short paragraph I can save.
Reflection Prompt 2 — Your word list
This gives you a concrete vocabulary map — the words that are distinctly yours and the ones that feel completely off-brand.
Help me create a "voice vocabulary" list for my brand. Ask me: What are 5 words or phrases I use all the time? What are 5 words that sound nothing like me (too corporate, too casual, or just wrong)? What 3 adjectives would my best clients use to describe how I communicate? Compile my answers into a "Words I Use / Words I Avoid" table I can reference later.
Reflection Prompt 3 — Your origin story instincts
How you tell your "why" reveals a lot about voice. This exercise pulls out your natural storytelling style.
I'm going to write 3–5 sentences about why I do the work I do — whether that's why I started my business, why I joined my company, or what drives me in my role — completely off the top of my head — no editing. After I write it, I want you to analyze my writing style: How long are my sentences? Do I use "I" a lot or do I step back? Am I more analytical or emotional? Do I use metaphors? What's the overall energy? Give me a short style analysis I can add to my voice guide.
Reflection Prompt 4 — What you believe
Your opinions and beliefs are what make your voice magnetic. AI can learn them if you name them explicitly.
I want to document the opinions and beliefs that shape my content voice. Ask me: What's one thing I believe about my industry that most people don't say out loud? What do I push back on that's "standard advice" in my field? What does my ideal client believe that most people don't understand yet? Turn my answers into a "Core Beliefs" section for my voice guide.
Set Up Claude
Training Claude to sound like you works best when you use Claude Projects — a feature that lets you give Claude a persistent set of instructions it remembers every time you start a new conversation inside that project. Think of it as your AI's home base, pre-loaded with everything it needs to know about you.
Step 1 — Create your writing project
- Go to claude.ai and sign in to your account.
- In the left sidebar, click "New Project" (or the + icon next to Projects).
- Name it something clear, like "My Writing Voice" or "[Your Name] Content Studio."
- Click into Project Instructions — this is where you'll paste your voice guide.
- Every conversation you start inside this project will automatically have access to your voice guide.
Step 2 — Paste your voice guide into Project Instructions
Below is a master template for your Project Instructions. Fill in the bracketed sections using what you discovered in Tab 1. Paste the completed version into your Claude Project's instruction field.
## My Voice Guide **Who I am:** [Your name], [your title/role] at [your business name]. I help [your ideal client] to [the outcome you deliver]. **My audience:** [Describe your ideal reader — their situation, what they want, how they talk] **My tone:** [e.g., warm and direct / professional but never stiff / conversational with depth] **How my writing sounds:** - Sentence length: [e.g., mix of short punchy sentences and longer flowing ones] - Personality: [e.g., I'm encouraging but I don't sugarcoat / I use humor but stay grounded] - I write like I'm talking to: [e.g., a smart friend who needs clarity, not convincing] **Words and phrases I naturally use:** [List 5–8 of your go-to words or phrases] **Words I never use (off-brand for me):** [List 5–8 words that sound wrong / too corporate / too casual] **My core beliefs:** - [Belief 1] - [Belief 2] - [Belief 3] **What I never do:** - Use buzzwords like "synergy," "leverage," or "game-changer" - Start every sentence with "I" - Sound preachy or lecture-y - Use excessive exclamation points!!! **My content goal:** Every piece I write should make my reader feel [e.g., seen, capable, and excited to take action]. --- When writing for me, always match this voice exactly. If something feels off-brand, flag it and offer an alternative. Never default to generic marketing language.
Step 3 — Test it with a quick check
Once your instructions are saved, start a new conversation inside the project and paste this test prompt:
Before we start working together, summarize back to me: Who am I, who do I write for, and what are 3 key things about my voice that you'll always keep in mind? Then write two sample sentences in my voice about [any topic related to your work].
Train It
Your voice guide tells Claude about your voice. But examples teach it how your voice actually moves on the page. The combination of instructions plus real writing samples is what takes Claude from "pretty good" to "that actually sounds like me."
What makes a good training example?
Use these
- Your best-performing social posts
- Emails your subscribers replied to
- Blog posts you're proud of
- Voice memos you've transcribed
- Sales page copy that converted
- Newsletter intros that felt right
Avoid these
- Content you wrote while rushing
- Posts you felt were "off" or stiff
- Work you had someone else write
- Overly promotional pieces
- Very old content (your voice evolves)
- Content from a different audience era
Training Prompt — Feed Claude your examples
Use this prompt each time you add new writing samples. Paste it, then include your actual content below it in the same message.
I'm going to share [number] examples of my real writing. Please read them carefully and update your understanding of my voice. For each one, note: the sentence rhythm, any patterns in how I open or close, emotional tone, specific phrases that feel distinctly mine, and anything that surprised you. After reading all of them, tell me the top 3 voice patterns you noticed that I should make sure you always replicate. [PASTE YOUR WRITING EXAMPLES BELOW THIS LINE]
Training Prompt — Deep voice analysis
Run this after sharing examples for a more structured voice breakdown you can add back to your Project Instructions.
Based on the writing examples I've shared, create a detailed voice analysis with these sections: 1. RHYTHM — How do my sentences flow? Short/long patterns? Any signature structures? 2. OPENINGS — How do I tend to start paragraphs or pieces? 3. CLOSINGS — How do I tend to end things? Call to action style? 4. PERSONALITY MARKERS — Specific quirks, humor, warmth that appear repeatedly 5. WHAT TO AVOID — Anything you noticed I consistently do NOT do? Format this so I can paste it directly into my Project Instructions as an addendum.
Training Prompt — Upload to your Project Knowledge
Claude Projects also let you upload files. Use this to introduce a document you've uploaded.
I've uploaded a file called [filename] to this project. It contains examples of my writing. Please read the entire document before we do any writing work together. Treat it as a reference for how I naturally communicate — my rhythm, my vocabulary, my warmth level, how I frame ideas. You don't need to summarize it unless I ask; just use it to inform every piece of writing you create for me.
Prompt Toolkit
These are your ready-to-use content prompts — designed to work inside your Claude Project where your voice guide already lives. Each one includes a placeholder for your specific topic. Just fill in the bracket and go.
Long-form post intro + outline
Write a blog post intro (3–4 paragraphs) and a full outline for a post titled: "[YOUR TITLE HERE]" The intro should hook my reader immediately — not with a statistic, but with a relatable moment or a question that makes them lean in. Keep my voice: [remind Claude of 1–2 key voice traits if needed]. The outline should have 4–6 main sections with a 1-sentence description of what each covers. End with a conclusion that leads naturally into a call to action.
Nurture email (story-driven)
Write a nurture email to my list about: [TOPIC OR LESSON] Structure: Open with a short story or moment (2–3 sentences), transition into the lesson or insight, then connect it to something my reader is probably experiencing right now. Close with one clear, low-pressure call to action: [describe the CTA, e.g., "reply to this email" or "check out the link below"]. Aim for 250–350 words. Subject line options: give me 3, ranging from curiosity-driven to direct.
Engaging social caption
Write an Instagram caption for a post about: [DESCRIBE THE POST OR TOPIC] Keep it conversational and real — not polished to the point of feeling fake. Open with a line that stops the scroll (not a question, not an emoji, just a strong sentence). Use short paragraphs for mobile readability. End with either a genuine question to spark comments or a soft CTA. Length: 100–180 words. Also give me 5 relevant hashtag suggestions.
Thought leadership post
Write a LinkedIn post sharing my perspective on: [TOPIC OR OBSERVATION] Format for LinkedIn: strong opening line (no "I'm excited to share" type openers), then 3–5 short punchy paragraphs, then a takeaway or question at the end. Professional but human — I want it to sound like a smart person talking, not a press release. My unique angle on this topic is: [YOUR ANGLE]. Make sure that comes through clearly.
Sales page section
Write the "Who this is for" section of a sales page for: [OFFER NAME AND DESCRIPTION] This section should make the right reader feel immediately seen — like I wrote this specifically for her. Name the situation she's in, the feelings she's carrying, and what she's already tried that hasn't worked. Be specific and empathetic, not generic. Avoid bullet-point fatigue — use flowing sentences, not just a list. End with a 1-sentence bridge that moves her toward the offer: "If that's you, [offer name] was built for exactly this."
Weekly newsletter issue
Write this week's newsletter. Theme / main topic: [TOPIC] One thing I want my reader to walk away knowing or feeling: [OUTCOME] Any personal story or context I want woven in: [OPTIONAL — share a brief note] Structure: warm opening (2–3 sentences that don't start with "This week"), a main section with the insight or story (200–250 words), a short "quick tip" or resource callout, and a closing that feels like a genuine goodbye from me — not a sign-off template. Total length: 350–450 words.
New subscriber welcome email
Write a welcome email for someone who just joined my email list. They signed up because: [LEAD MAGNET OR REASON] What I want them to feel: welcomed, like they made a smart move, and curious about what's coming What I want them to do: [e.g., reply and introduce themselves / click to read the freebie / follow me on Instagram] Make it feel like a real person wrote it — warm, a little personal, no corporate "you're officially subscribed!" energy. Under 250 words. Subject line: give me 2 options.
Turn one piece into many
I'm going to paste a piece of content I've already written. Please turn it into: - 3 Instagram captions (different angles) - 1 LinkedIn post - 1 email subject line + opening paragraph - 2 tweet-length (280 char) versions Keep my voice consistent across all formats. Adjust the register slightly for each platform (Instagram = warmer and more personal, LinkedIn = slightly more professional, email = like a letter). [PASTE YOUR ORIGINAL CONTENT HERE]
Refine & Fix
Claude won't always nail it on the first try — and that's completely normal. The real skill is knowing how to redirect it without starting over. These prompts help you fix specific problems quickly and build a feedback loop that makes Claude better every time.
When it sounds corporate instead of you
Claude defaulted to professional mode. It's accurate, but it doesn't sound like you'd actually say it.
This sounds too formal — like a business report, not me. Rewrite it with more of my natural rhythm. Loosen the sentence structure, remove any corporate language, and add a little more warmth. Think of it as me talking to a friend who happens to be my ideal client, not presenting to a boardroom.
When it sounds like it's trying too hard to be relatable
Too many exclamation points, overly peppy energy, or filler phrases like "Let's dive in!" or "Buckle up!"
This is too energetic and forced. Dial it back — I'm warm but I don't use hype language. Remove any phrases that feel performatively enthusiastic (like "Let's dive in!" or "So excited to share!"). Keep the friendliness but ground it. I want to sound like someone who's genuinely confident, not cheerleading.
When it's informative but missing your point of view
The content is factually fine but feels generic — it could have been written by anyone.
This is accurate but it sounds like anyone could have written it. I need my perspective in here — my specific take, not just the general consensus. Rewrite it so it reflects what I actually believe about this topic. My angle is: [briefly state your take]. Build the content around that viewpoint, not just the information.
When it's too long, too short, or padded
This is longer than it needs to be. Cut it down to [target word count] words without losing the core message. Prioritize: the hook, the main insight, and the CTA. Remove anything that's restating what was already said or padding for length.
When the opening doesn't pull you in
The opening isn't strong enough — it doesn't make me want to keep reading. Give me 5 different opening lines for this piece, ranging from: a bold statement, a relatable moment, a counterintuitive claim, a direct address to my reader, and a short story setup. I'll pick the one that feels most like me.
The feedback loop: how to get better over time
Every time Claude misses, that's data. The fastest way to improve your results is to name exactly what's wrong and tell it why. Use this prompt to turn a correction into a permanent improvement:
I want to update your understanding of my voice. The draft you just wrote [describe what was off — e.g., "was too listy" / "had too much hype energy" / "used words I don't use"]. Going forward, please remember: [state the specific adjustment]. Can you confirm you've noted this and rewrite the section with that in mind?
Common Mistakes
These are the most common things people do when training AI to write in their voice — and the honest reasons why they don't work. None of these are catastrophic. They're just good to know before you hit them.
You set up your voice guide, then open a regular Claude chat to "just ask a quick question" — and the writing comes back generic. That's because regular chats have no access to your Project Instructions. Your voice training doesn't travel.
"Write in a warm, professional tone" is something every AI tool has heard ten thousand times. It's too generic to be useful. If your instructions don't include specific examples, vocabulary lists, and things you never do — Claude is guessing.
AI-assisted writing is still a collaboration. When you skip the review step — especially early on — you train yourself to accept writing that doesn't quite sound like you. That creates a gradual drift away from your actual voice.
Your Instagram voice and your email voice are siblings, not twins. What works in a casual caption can feel too breezy in a sales email — and what lands in a newsletter can feel too long for LinkedIn. Claude needs context on the format, not just the topic.
Instructions alone are not enough. Telling Claude "I write warmly and directly" is like telling a new employee your culture without showing them anything. Examples show Claude what those words mean in practice.
Your voice changes. Your business matures, your audience shifts, your confidence grows. A voice guide written a year ago might be training Claude to sound like an earlier version of you — one you've grown past.
You're further along than you think.
Most people who struggle with AI writing tools haven't set them up properly. Now you have. The prompts, the Project setup, the training examples — this is what separates content that sounds like a robot from content that sounds like you. Give it a real try before you judge the results. Your voice is worth the effort.
