More Than One Wiki

Keeping separate wikis for separate worlds — and wondering how they relate? A document in MojoPad is a whole wiki: one folder on your Mac holding its pages, its files and its indexes. Many people keep several — one per project, per field, per client — to keep the noise down in each. This is what does and doesn't reach across the line between them, said plainly, because knowing where a boundary is beats discovering it later.

A document is a closed world, on purpose

Everything MojoPad works out about your writing, it works out inside one document. Search, backlinks, the graph, tags, tasks, the meaning index that powers related pages and Ask, the auto-linking that connects a phrase to a page of the same name — all of it stops at the edge of the document.

That isn't an omission so much as the thing that makes a document what it is. A wiki you can copy to a drive, hand to a colleague, back up, open on another Mac or leave untouched for five years has to be complete in itself. A document that reached into its neighbours would be none of those things — and it would be a document whose meaning changed depending on what else happened to be on the disk.

What does cross

• Searching your other wikis. Search as usual, and under the results there's Also search your other wikis. Press it and MojoPad reads them off the disk then and there — grouped by wiki, with the number found in each, and clicking a result opens that page in the wiki it belongs to. Choose… beside it picks which wikis a wider search looks in, and remembers. It happens only when you ask: nothing is indexed, nothing is kept, and no copy of one wiki's writing ever lands anywhere near another's. A wiki with a password isn't searched and says so by name, so a short list is never mistaken for an empty one.
• Links between wikis. Edit ▸ Copy Link to Page (⌃⇧⌘C) copies a link to the page you're on. Paste it into a page in another wiki — or into an email, a task manager, a terminal, anywhere on your Mac — and clicking it opens that page, in that wiki, whether or not it's already open. This is the direct answer to "can one wiki point at another": yes, page by page, and the link keeps working from outside MojoPad entirely.
• Several wikis at once. Each opens in its own window and they run side by side; File ▸ Open Recent keeps the ones you use to hand.
• An AI agent can read across the wikis you use. This is the one place something genuinely spans your shelf. With the MCP server connected (see AI Agents), an agent can be pointed at any wiki you've opened in MojoPad — whether or not it's open now — to search it, list its pages, read one, or write a new one. So "look across these three wikis and tell me where they touch" is a question you can ask today, of an agent, even though MojoPad's own search box only ever looks in the wiki in front of you. A wiki you've never opened here stays out of reach unless you say otherwise, and a password-protected one always does.

What doesn't

Beyond that deliberate search, nothing else spans wikis. There is no graph across them, no weekly review over a set of them, and nothing relates them by meaning — the index behind related pages and Ask stays inside its own document, so what you write in one wiki never surfaces while you're working in another. A page in one wiki cannot auto-link to a page in another by name — auto-linking only knows the document it's in. If you want two bodies of work to see each other that closely, they want to be one document with folders rather than two documents.

Choosing how to split

The useful question isn't "how many wikis" but "what would I want to search in one go". Things you'll want to find together, or that should link to each other by name as you type, belong in one document; folders and tags will keep them tidy without walling them off. Keep separate documents for work that is genuinely separate — a different client, a different part of your life, anything with its own privacy or backup story — and use a copied page link where the two genuinely need to touch.
