    Taste File: How to Make AI Write Exactly Like You

    Your voice has a DNA. Here is the exact process to extract it, encode it in a portable file, and plug it into any AI so it reliably thinks and writes like you, on demand.

    You have tried custom instructions. You have written "use a casual tone" in your prompts. And the AI still sounds like a corporate intern writing a LinkedIn post.

    The problem is not the AI. The problem is that you have not given it enough signal about who you actually are. A two-sentence instruction is not a voice. It is a vibe. And AI cannot work with vibes.

    A Taste File fixes this. It is a structured markdown document, built through a 100-question interview, that captures your beliefs, writing mechanics, aesthetic boundaries, and personality so precisely that any AI can write as you, not just for you.

    The core idea

    Your taste is mostly boundaries. Once the things you will not say live in a file, your voice becomes portable across every AI tool you use.

    What Is a Taste File?

    A repeatable way to turn your voice into context any model can read.

    Taste Filenoun · portable voice profile

    A structured markdown document that captures your writing voice, beliefs, stylistic preferences, and hard boundaries so any AI can write content that sounds like you, not like generic AI output.

    A repeatable extraction process

    A structured interview prompt that turns your voice, beliefs, and taste into a portable .md file AI can use as context.

    A boundary-first framework

    It forces you to define what you reject, not just what you like. That is where your real voice lives, in the things you would never write, say, or tolerate.

    A reusable format

    Use it for yourself, your team, or any persona you want to model. One file, every AI tool: Claude, ChatGPT, Gemini, Grok, and anything that comes next.

    Why Most "Write in My Voice" Prompts Fail

    Telling an AI to sound like you gives it almost nothing to work with.

    The real problem

    Without strong context, every AI writes the same way: hedging language, "in today's fast-paced world" openings, and conclusions that begin with "In conclusion." That is the statistical middle, and your audience can smell it instantly.

    How to Create Your Taste File in 5 Steps

    The whole process takes 60-90 minutes. Do it once, reuse the file indefinitely.

    1. Open your AI of choice

      Claude, ChatGPT, Gemini, any model with a long context window works. You need space for a 100-question conversation, so models with larger context tend to produce better results.

      Tip: start a fresh chat with no prior context.

    2. Paste the Taste Interviewer prompt

      Copy the full prompt (included below) and paste it into your new chat. This turns the AI into a relentless questioner designed to break through vague, surface-level answers and get to the real you.

      Expect the AI to push back and ask for examples.

    3. Answer 100 questions honestly

      The interview covers 7 categories: beliefs and contrarian takes, writing mechanics, aesthetic crimes, voice and personality, structural preferences, hard nos, and red flags.

      15 + 20 + 15 + 15 + 15 + 10 + 10 = 100 questions.

    4. Generate your Taste File

      After 100 questions, the AI compiles everything into a structured markdown document. Not a summary, a complete reference preserving the full depth of every answer, with a Quick Reference Card and an Anti-Overfitting Guide.

      Output: Voice Profile, full Q&A, quick reference, usage guide.

    5. Use it everywhere

      Download the .md file and attach it to any future AI session. Paste it at the start of a chat, upload it as an attachment, or set it as a project-level instruction. Then prompt as normal.

      Works across Claude, ChatGPT, Gemini, Grok, and whatever comes next.

    The 7 Categories That Define Your Voice

    Each category captures a different dimension of your voice DNA.

    Beliefs & contrarian takes

    15 questions

    What you believe that others in your field do not. Without these, AI writes the consensus view, the opposite of a personal voice.

    Writing mechanics

    20 questions

    How you actually write, not how you think you write. This is the fingerprint: rhythm, length, word choice.

    Aesthetic crimes

    15 questions

    What makes you cringe. Knowing what to avoid is often more useful than knowing what to do, so this gives AI a clear "never" list.

    Voice & personality

    15 questions

    How you use humor, your tone serious versus casual, how you handle disagreement. The subtleties that separate you from a professional-sounding bot.

    Structural preferences

    15 questions

    How you organize ideas, your relationship with lists and headers, how you handle transitions. Structure is voice.

    Hard nos

    10 questions

    Things you would never write about. Lines you will not cross. Non-negotiables the AI should never break.

    Red flags

    10 questions

    What makes you immediately distrust content. This trains the AI quality filter so it never produces patterns you hate.

    The Built-In Anti-Overfitting Guide

    The file ships with a built-in guide that stops the AI from trying too hard.

    Here is where most voice-capture attempts go wrong: the AI forces in every tendency until the output reads like a parody of you. The Taste File prevents this by telling the AI how to hold your patterns lightly.

    Spirit over letter. A piece that uses 3 tendencies naturally beats one that forces in 10 awkwardly. Internalise the sensibility, do not mechanically apply every pattern.

    Frequency guidance. Each tendency is labeled Hard Rule (never violate), Strong Tendency (70-80% of the time), or Light Preference (context-dependent). Default: light preference.

    Context awareness. A tweet is not a newsletter is not a LinkedIn post is not a long-form article. The guide tells the AI to adapt patterns to format, not force consistency everywhere.

    The litmus test. Before finalizing: does this sound like something I would actually write, or like an AI trying very hard to imitate me? If forced, pull back. Less imitation, more inhabitation.

    The Complete Taste Interviewer Prompt

    Copy this entire prompt and paste it into a new chat. It starts interviewing you immediately.

    taste-interviewer-prompt.md
    You are a Taste Interviewer, a relentless interviewer whose job is to extract the DNA of how I think, write, and see the world. Your goal is to create a comprehensive document that captures my unique voice so precisely that another AI instance could write and think exactly like me.
    
    <interview_philosophy>
    
    You're not here to be polite. You're here to get to the truth. Most people can't articulate their own taste. They give vague, socially acceptable answers. Your job is to break through that.
    
    </interview_philosophy>
    
    <interview_structure>
    
    Conduct 100 questions total across these categories (not necessarily in order, follow the thread when something interesting emerges):
    
    BELIEFS & CONTRARIAN TAKES (15 questions)
    
    - What I believe that others in my field don't
    - Hot takes I'd defend to the death
    - Conventional wisdom I think is wrong
    
    WRITING MECHANICS (20 questions)
    
    - How I actually write (not how I think I write)
    - My default sentence structures
    - How I open pieces / How I close them
    - My relationship with punctuation, formatting, line breaks
    - Words I overuse / Words I love / Words I'd never use
    
    AESTHETIC CRIMES (15 questions)
    
    - What makes me cringe in other people's writing
    - Specific phrases or patterns that feel like nails on a chalkboard
    - Types of content I find lazy or uninspired
    
    VOICE & PERSONALITY (15 questions)
    
    - How I use humor (if at all)
    - My tone when I'm being serious vs. casual
    - How I handle disagreement or controversy
    - What I sound like when I'm excited vs. skeptical
    
    STRUCTURAL PREFERENCES (15 questions)
    
    - How I organize ideas
    - My relationship with lists, headers, bullets
    - How I handle transitions
    - My default content structures
    
    HARD NOs (10 questions)
    
    - Things I'd never write about
    - Approaches I'd never take
    - Lines I won't cross
    
    RED FLAGS (10 questions)
    
    - What makes me immediately distrust a piece of content
    - Signals that someone doesn't know what they're talking about
    
    </interview_structure>
    
    <interview_rules>
    
    1. ONE question at a time. Wait for my response before moving on.
    2. Push back on vague answers. If I say "I like to keep things simple," ask "Simple how? Give me an example of simple done right and simple done lazy."
    3. Ask for specific examples. "Show me a sentence you've written that captures this."
    4. Call out contradictions. If I said one thing earlier and something different now, point it out.
    5. Go deeper on interesting threads. If something unusual emerges, follow it.
    6. Don't accept "I don't know" easily. Try reframing the question or approaching from another angle.
    
    </interview_rules>
    
    <output_requirements>
    
    After exactly 100 questions, compile everything into a comprehensive markdown document. This is NOT a summary. It's a complete reference document preserving the full depth of every answer.
    
    Structure it like this:
    
    # VOICE PROFILE: [My Name]
    
    ## Core Identity
    
    [2-3 sentences capturing the essence. This is the only summary section]

    ## HOW TO USE THIS DOCUMENT (ANTI-OVERFITTING GUIDE)
    
    This document captures my taste. It is NOT a checklist to follow rigidly.
    
    ### Spirit Over Letter
    
    The goal is to internalize my sensibility, not to mechanically apply every pattern. A piece that uses 3 of my tendencies naturally will always beat a piece that forces in 10 of them awkwardly.
    
    ### Frequency Guidance
    
    For each tendency documented above, note whether it's:
    
    - **HARD RULE**: Never violate (these are rare, usually in the "Never" section)
    - **STRONG TENDENCY**: Do this 70-80% of the time, but breaking it occasionally is fine
    - **LIGHT PREFERENCE**: Nice to have, but context determines when to apply
    
    When no label exists, assume it's a LIGHT PREFERENCE.
    
    ### Context Matters
    
    My voice adapts to format:
    
    - A tweet ≠ a newsletter ≠ a LinkedIn post ≠ a long-form article
    - Use judgment about which patterns fit which format
    - Some of my tendencies are format-specific, note when this applies
    
    ### Natural Variation
    
    Real writers aren't perfectly consistent. Introduce natural variation:
    
    - Don't start every piece the same way just because I have a "signature open"
    - Don't avoid a word forever just because I said I dislike it. Sometimes it's the right word
    - Let the content dictate structure, not the template
    
    ### The Litmus Test
    
    Before finalizing anything written "as me," ask:
    
    > "Does this sound like something I would actually write, or does it sound like an AI trying very hard to imitate me?"
    
    If it feels forced, pull back. Less imitation, more inhabitation.
    
    ### What Matters Most
    
    If you forget everything else, remember these 3 things:
    
    1. [My single most important belief about writing]
    2. [The one pattern that makes my voice mine]
    3. [The #1 thing I never do]
    
    Everything else is secondary.
    
    ***
    
    ## INSTRUCTIONS FOR AI
    
    When writing as [My Name], reference this document. Pay attention to:
    
    1. The specific examples I gave: use similar structures.
    2. The words and phrases I said I hate: never use them.
    3. The beliefs I hold: let them inform the angle.
    4. My actual sentences: match the rhythm and length.
    
    This document is a source of truth, not a suggestion. Apply it with judgment, not rigidly.
    
    </output_requirements>
    
    Begin by asking me your first question.

    Tips for the best results

    Be specific. "I write short sentences" is vague. "My paragraphs rarely exceed 3 sentences and I never use semicolons" is useful.

    Give real examples. When the AI asks for a sentence that captures your style, paste an actual one from something you have written.

    Do not edit yourself. If your honest answer is that you swear in your writing and you are not stopping, say that. The Taste File is for accuracy, not aspiration.

    Embrace contradictions. Real people are inconsistent. If the AI catches a contradiction, explore it. That is often where your most interesting voice patterns live.

    What You Can Do With Your Taste File

    Once you have it, the applications go well beyond writing a blog post as you.

    Content creation. Blog posts, newsletters, social captions, email sequences, all in your voice without manually editing every output.

    Team alignment. Share your Taste File with writers, VAs, or agencies. They feed it to their AI tools and immediately match your voice, no weeks of getting to know you.

    AI clone foundation. A Taste File is the first layer of building a full AI clone of yourself, one that can respond to your audience, coach your clients, or handle DMs at scale.

    Personal brand at scale. Produce 10x the content without sounding generic. Your Taste File ensures consistency across every channel, format, and tool you use.

    Frequently Asked Questions

    Everything you need to know about building and using a Taste File.

    What is a Taste File?+

    A Taste File is a structured markdown document that captures your writing voice, beliefs, stylistic preferences, and hard boundaries so any AI can write content that sounds like you, not like generic AI output.

    How long does it take to create a Taste File?+

    The full interview process takes roughly 60-90 minutes. The AI asks you 100 questions across 7 categories, then compiles everything into a portable markdown file you can reuse indefinitely.

    Does a Taste File work with any AI?+

    Yes. Because it's a plain markdown file, you can use it with Claude, ChatGPT, Gemini, Grok, or any LLM that accepts context. Just paste or attach it at the start of a session.

    Why does the interview focus so much on what I reject?+

    Your taste is mostly defined by boundaries, things you won't say, won't tolerate, and won't compromise on. Without those boundaries, AI defaults to a generic 'statistical middle' that sounds like everyone and no one.

    How is a Taste File different from custom instructions?+

    Custom instructions are typically short and surface-level (e.g. 'write casually'). A Taste File is a deep, comprehensive reference document with 100 data points across beliefs, mechanics, aesthetics, personality, structure, and hard boundaries. It gives AI far more signal to work with.

    Can I update my Taste File over time?+

    Absolutely. Run the interview again after 6-12 months, or edit sections manually as your style evolves. Your voice changes, and your Taste File should too.

    Want to go further than a file?

    A Taste File captures how you write. An AI clone captures how you think, coach, and interact. Personify builds full AI versions of coaches, creators, and experts, trained on your content, your style, and your methodology.
