Settings
Vault settings holds the few settings that apply to every document in your vault. Open it from the three dots next to the vault's name in the sidebar, or with Settings… in the app's menu (Cmd+, on a Mac, Ctrl+, on Windows).
| Setting | What it does |
|---|---|
| Title | The name shown in the sidebar and in the window's title. Left empty, the folder's name is used |
| Default theme | The look of your documents, picked from the built-in theme and any others in the vault. A document can still choose its own |
| Page size | A4 or Letter, for PDFs and the paginated layout. The theme's leaves the choice to the theme |
| Default layout | Whether a document opens as one continuous page or laid out in pages |
| "Made with Plicine" line | The one line at the end of PDFs. It's on to begin with and free to turn off; see The credit line |
| Public URL | If a copy of your vault is published on a website, its address. PDFs then end with a link and a QR code to the same page there. Most people leave it empty |
| Go to a document | The keys that open the box for jumping to a document by its name: Cmd+K, which is what Notion uses, or Cmd+P, which is what Obsidian uses. On Windows it's Ctrl with the same letter |
| AI agents | The agent bar under your documents, its row at the foot of the sidebar and its shortcut. It's on to begin with. Turn it off and all three go, and no agent can run in this vault; see Turning agents off |
| Write AGENTS.md | Keeps a briefing file in the folder for an AI agent that you run from a terminal. Leave it off unless you use one. It doesn't depend on AI agents; Working with an AI agent explains it |
There's no Save button. A switch or a list saves as you change it, and Title and Public URL save when you press Enter or click somewhere else. The document you have open picks the change up straight away.
The settings are saved inside the folder, so they travel with it: everyone who shares the vault gets the same theme and page size.
Your name
Under You, at the foot of the same screen, is the one setting that's yours and not the vault's. Your name is what your comments are signed with. Plicine fills it in from the name your computer knows you by, so most people never touch it. Type another to sign with that, or empty the box to go back. It's kept on your computer and not in the folder, so each person who shares the vault has their own.
For technical readers: the settings live in a small file you can also edit by hand, along with a few settings the screen doesn't show. vault.json and frontmatter lists all of them.
