The Problem with AI Writing
You've tried using ChatGPT for emails. Claude for documents. Gemini for drafts.
They all have the same problem: they don't sound like you.
Every output needs heavy editing. The tone is off. The transitions are wrong. It uses words you'd never use. And it adds em-dashes everywhere.
You end up spending almost as much time fixing AI drafts as you would writing from scratch.
Worse if you're multilingual:
- 01Your English is direct and confident
- 02Your Japanese needs the right level of keigo
- 03Your French has a different rhythm entirely
No AI tool handles this. You're stuck switching voices manually, losing time, losing consistency.
The Hidden Cost of Generic AI
Every email you rewrite is time you'll never get back.
20 emails per day x 5 minutes of editing = 100 minutes lost daily
That's 8+ hours per week fixing AI output
Over a year: 400+ hours — ten full work weeks
And that's just email. Add Slack, documents, presentations...
The real cost isn't just time. It's cognitive load.
Constantly switching between "what AI wrote" and "what I would actually say" is exhausting. It fragments your focus. It slows you down.
You didn't adopt AI to work harder.

Frequently Asked Questions
How is this different from prompt packs?
Prompt packs give you generic templates that work the same for everyone. They tell AI to "be professional" or "sound friendly."
MyWritingTwin is fundamentally different. We forensically extract YOUR writing patterns from YOUR actual writing samples. The result captures:
- -- Your actual vocabulary (not generic "professional" words)
- -- Your sentence rhythm (short punches vs. flowing paragraphs)
- -- Your transition patterns (how YOU connect ideas)
- -- Your formality shifts (how you write to your CEO vs. your team)
- -- Your cultural and linguistic nuances (keigo levels, tu/vous, etc.)
Prompt packs tell AI what to sound like. Style Profiles show AI how you actually write, with concrete examples. That's why AI trained on your Style Profile produces output you can use with minimal editing.
Do I need technical skills?
Not at all. If you can copy-paste and follow step-by-step instructions, you can build your Writing Twin. We provide detailed guides for every step of the process.
Which AI platforms does this work with?
All of them. We include specific guides for ChatGPT (Custom GPTs), Claude (Projects), and Gemini (Gems). The Runtime Block works with any LLM, including API usage.
How long does setup take?
Here's the breakdown:
- • Collecting samples: 15-60 minutes (depending on how organized your writing is)
- • Questionnaire + setup: 10-15 minutes
- • Deploying: 10-15 minutes per platform
Total: Under 2 hours for a system you'll use daily.
What if I only speak one language?
MyWritingTwin works great for single-language users. You'll get style consistency across different contexts (email vs Slack vs documents) even in one language. The Starter plan ($49) is designed exactly for this: one language, up to 3 style contexts, everything you need to get AI writing like you.
What if it doesn't work for me?
We offer a 14-day satisfaction guarantee. If MyWritingTwin doesn't help you create an AI Writing Twin that writes like you, email us for a full refund.
How does the output work with ChatGPT/Claude/Gemini?
You get a master prompt file that you paste into any AI tool's system instructions. It works with ChatGPT Custom GPTs, Claude Projects, Gemini Gems, or any LLM that supports system prompts. One file, works everywhere.
Do I need to re-run this every time?
No, your Style Profile works indefinitely. Once generated, you can use it for months or years. All plans include 1 free regeneration if you want to refine your profile after initial testing. For ongoing updates, our Edit subscription ($29/year) provides unlimited regenerations.
What if my writing style evolves or I want to add new languages, formats, or targets?
Subscribe to the Edit plan ($29/year, or $10 first year for Pro users) to update your profile anytime. Add new writing samples, expand to new languages, add new communication contexts, and regenerate as often as you need. Your Style Profile grows with you.
Can I use this with multiple AI tools?
Yes! The output works with ChatGPT, Claude, Gemini, and any other LLM. You can deploy your Style Profile across all your AI tools simultaneously. Same authentic style everywhere.
What exactly do I receive when I purchase?
You get two optimized outputs designed to work together:
Writing Style Profile (~6-8K tokens): The Writing Style Profile (~6-8K tokens) is your personalized writing analysis. It reveals your distinctive patterns, voice characteristics, and context-specific behaviors with real examples from your writing. Read it to understand what makes your communication style unique.
Runtime Block (~3-4K tokens): The Runtime Block (~3-4K tokens) is optimized for deployment. It's the efficient system prompt you paste into ChatGPT, Claude, or any AI platform. Compact enough to avoid token waste, detailed enough to capture your authentic voice.
Why two outputs? Why two outputs? The Profile is written for you to read and learn from — too rich for direct AI use. The Block is compressed for AI execution but too dense for human reading. Together, they give you both understanding and performance.
