# About AI Twins

## What is an AI Twin?

An AI Twin is a version of **your** knowledge that can answer for you when you are not in the room. Visitors chat at your public link; answers are grounded in what you upload — not a generic chatbot trained on the whole internet.

## Purpose

AI Twins help you share expertise, explain your work, and stay reachable without repeating yourself. You control what goes in, who can see private material, and how the Twin sounds.

## Use cases

- **Personal knowledge** — FAQ, bio, articles, and notes available 24/7
- **Audience interaction** — Let people explore your ideas; see what they ask in Analytics
- **Professional presence** — A link you can put on your site, email signature, or event page

## How it differs from plain ChatGPT

### Your knowledge stays separate

- Your files live in **your** knowledge base in the console
- They are not used to train the underlying model
- Each answer retrieves relevant passages from your content first

### Privacy by design

- You choose what is public vs invite-only
- Private knowledge requires verified email (and optional domain rules)
- You can update or remove material anytime

### Behavior you control

- Intro, avatar, theme, personality, example questions, disclaimer
- Response length and conversational style on Profile
