Connecting knowledge to a Custom AI

What you can connect

• Boards — a whole board becomes a live source. Your research board, your ideas board, a client's brand board.
• Notes and saved items — individual documents, highlights, and posts from your Library.
• Files — drop in Markdown, PDFs, and docs. They're saved to your Library first, then attached, so the same file is usable everywhere in Eden, not trapped inside one AI.
• Links — paste a URL and Eden saves and indexes it as a source.
• Creators — a creator's public posts as reference material, with a role you choose. See adding creators as sources.

Add from anywhere with right-click

You don't have to open the Custom AI editor to grow its knowledge. Right-click an item where you already are and choose Add to Custom AI:

• On a board — any card or a whole board card. Multi-select first to add several at once.
• In your Library — any saved item, note, or board.
• In Discover and on creator profiles — any post card, added as a social post source.

Pick the Custom AI from the list and the item is attached with the same live, retrieve-when-relevant defaults as adding it from the editor. If it's already connected, Eden tells you instead of duplicating it.

From the chat sidebar

While you're chatting with a Custom AI, the sidebar to the right of the conversation lists its knowledge. Use Add there to attach a workspace item, upload a file, paste a link, or add a creator without leaving the chat, and hover a source to disconnect it. See the chat sidebar.

Live means live

Board and note sources are pointers, not copies. Update the board tomorrow and the Custom AI works from the new version — no re-uploading. This is the difference between "I uploaded some files once" and a companion that stays current with your actual work.

How it decides what to use

You don't manage this per message. Each time you send a message, Eden looks at the connected sources, pulls in the ones relevant to what you asked, and leaves the rest out. Ask your study companion about chapter 3 and it reads chapter 3 — not all nine chapters.

Under the answer you'll see a small context line naming the sources it used. Each one is clickable. If it leaned on the wrong thing, tell it — "don't use that doc unless I ask" — and the correction sticks as a reviewable change.

One-off context stays one-off

You can still @-mention any item mid-chat for a single question. That attaches it to the conversation without making it permanent knowledge. Permanent sources are a deliberate act, so your Custom AI never quietly accumulates clutter.

Choosing the right amount

Narrow beats big. A Custom AI with the twelve documents that matter outperforms one drowning in three hundred "just in case" items — this is the whole point of building a narrowed context. Good rules of thumb:

• Start with the material you'd hand a smart new collaborator on day one.
• Prefer one well-kept board over many stale ones.
• If two topics never overlap, they probably want two Custom AIs — a study companion per subject, a brand AI per client.
