What is My Writing Twin used for?

My Writing Twin is a stylometry-based tool that creates a personalized profile of your writing style. You can deploy it with any AI (ChatGPT, Claude, Gemini) to generate emails, reports, Slack messages, and documents that sound exactly like you, saving time on editing.

How long does setup take?

Collecting writing samples takes 15-60 minutes, plus 10-15 minutes for the questionnaire and setup, and 10-15 minutes per platform to deploy. Total is under 2 hours for a system you'll use daily.

Can I use My Writing Twin with multiple AI tools?

Yes. You receive a Runtime Block that works with ChatGPT (Custom GPTs), Claude (Projects), Gemini (Gems), and any LLM via API. You can also use the Chrome extension for writing anywhere in the browser.

What if my writing style changes or I need to add new languages?

All plans include 1 free regeneration. For ongoing updates, subscribe to the Edit add-on ($29/year, or $10 first year for Pro) to add new samples, languages, and contexts and regenerate your profile as often as needed.

Q: How is My Writing Twin different from telling ChatGPT to 'write in my style'?

Generic AI guesses your style and uses its default house style with light adjustments. My Writing Twin measures your actual writing samples across 7 dimensions and 50+ markers, producing a precise profile. The difference is visible when you compare outputs side by side.

In-Depth Review: What is My Writing Twin?

My Writing Twin is a web application that uses computational stylometry to capture your unique writing voice and deploy it across any AI tool—ChatGPT, Claude, Gemini, and more. Unlike generic AI that produces robotic, one-size-fits-all text, My Writing Twin analyzes your actual writing samples across 7 dimensions and 50+ style markers, then creates a personalized Style Profile and Runtime Block. This means every output—whether email, Slack message, or document—sounds authentically like you, adapts to context (audience, language, medium), and requires minimal editing. It supports multilingual users, handles keigo, tu/vous, and different rhythms, and works with any LLM. With a free trial and paid plans starting at $49, it saves hours per week by eliminating the need to rewrite AI drafts.
