A Custom AI is a chat built around a chosen set of knowledge. Your docs, boards, books, and favorite creators, with your instructions and your voice. Every conversation starts inside the right context instead of a blank box.
Draft the next issue from my ideas board, in my voice. Quiz me on chapter 3 of the book I uploaded. What would my three saved experts say about this plan?
So you spend the first ten minutes re-explaining yourself.
Generic AI knows a little about everything and nothing about your work. Every session starts with the same ritual: paste the context, describe the audience, explain how you sound, hope it sticks. Tomorrow you do it again.
A Custom AI makes the explanation permanent. You choose exactly what it can see, a set of books, a research board, past issues, a few creators you trust, and you write down how it should behave. It stays that way across every conversation, like a room you furnished once.
Narrow context is the feature. The AI that sees only what matters can't wander off.
Three steps, ten minutes.
Connect boards, notes, and files from your Library, paste links, or attach creators whose public work it should study. Live sources stay current: update the board and the AI sees the new version.
Write the instructions: what it's for, how it should answer, what good looks like. Add your voice profile so drafts sound like you, and a few conversation starters for one-tap first messages.
Every conversation starts inside that world. Under each answer, a context line shows exactly which sources it used, and every chat collects on the Custom AI's own page.
Answers come from the material you chose, and each reply names its sources. Click through, check the original, correct it in one action.
Boards and notes attach as pointers, not copies. Keep working the way you already do, and every Custom AI reading them stays current.
Share one by link, give your team a house editor, or install ready-made specialists from Explore. Your private workspace never travels with it.
A Custom AI never silently reads your whole workspace. It works from the sources you connected, shows you which ones it used, and sharing never includes your boards, notes, or chats.
A normal chat starts blank and forgets your context. A Custom AI carries durable instructions, your voice, and a chosen set of knowledge, so every conversation starts already grounded in your material, and each answer shows which sources it used.
Boards, notes and saved items from your Library, uploaded files like PDFs and docs, pasted links, and creators whose public work it should study. Board and note sources are live, so the AI stays current as you keep working.
No. It sees only the sources you connect, and the context line under each answer shows exactly what it used. You can correct a wrong source in one click.
Yes. Share it by link and others can install their own copy. Your instructions and starters travel; your boards, notes, chats, and anything private do not. Where your version pointed at private material, their copy shows a named slot they fill with their own.
Creators draft with an editor that knows their voice and past work. Learners chat with a set of books or courses like a study tool. Marketers keep one sealed AI per client brand. Anyone who keeps re-explaining the same context to AI.
Start from the thing you already do every week: your newsletter, your reading, your client. Connect the material, set the behavior, and stop re-explaining yourself.
