How Amerus Works
Local at its core.
Connected when useful.
Amerus brings local intelligence together with your Memory, Vault, documents and the Connections you authorize — and keeps the whole of it on your own machine.
Getting started
Three steps, then it’s yours.
Install Amerus on your computer
Download, drag it to Applications, and open it. Amerus sets up its own local AI during first-run setup — no Terminal, no configuration files, no account to create.
Give it what you want it to know
Add documents to the Vault, connect folders you already keep on your computer or in iCloud Drive, and tell Amerus the things worth remembering. You choose every piece of it.
Ask it anything
Amerus answers from your own information, cites where each answer came from, and keeps the conversation on your machine. Online or off.
The four parts
What Amerus is made of.
Chat
Ask in plain language. Amerus draws on your documents, your Memory and its local intelligence to answer — and shows its work. Click any citation and the source document opens at the page, paragraph or spreadsheet tab the answer came from.
- Fast — everyday questions and quick lookups
- Balanced — the everyday default
- Deep — harder analysis and reasoning
- Print or share a conversation when you need a record
Vault
The Vault is where your documents live — contracts, statements, records, manuals, research, anything you want Amerus to be able to read. Everything in it is stored on your computer and encrypted at rest, and Amerus can search and reason across all of it at once.
- Search by name, tag or category
- Preview documents without leaving Amerus
- Keep a document private, share it with specific profiles, or make it available to everyone on that computer
Memory
Memory is what turns a chatbot into a personal aide. Tell Amerus something once and it holds on to it — how you like answers written, what your business does, who matters to you, what’s coming up. Your context compounds instead of resetting.
- Review, edit or delete any memory at any time
- Everyone gets their own profile, memories and history
- Optional PIN protection on each profile
Connections
Connections bring in information you already have, without leaving Amerus. Pick a folder on your computer or in iCloud Drive and Amerus indexes what’s inside and keeps it in sync. Point it at an Obsidian vault. Import an Apple Health export from your iPhone. On a Mac, add your Notes, Calendar, Reminders and Safari bookmarks.
Google Drive, Gmail, Dropbox, Microsoft and the Oura and Whoop wearables are built and coming soon — each is waiting on its provider to approve Amerus as an app. The full list is below.
- Connected files stay exactly where they are — Amerus never moves or copies them
- Exclude a folder or a single file whenever you like; Amerus stops using it and never deletes the original
- Disconnect a service and the connection closes

Coming soon means the connection is built and working, and is waiting on the provider — Google, Dropbox, Microsoft, Oura or Whoop — to approve Amerus as an application. It appears in the app automatically when that happens; there is nothing to update on your side. Four Mac-only connections draw on things that don’t exist on Windows — Notes, Calendar, Reminders and Safari — and simply don’t appear there.
The architecture, plainly
What lives where.
Everything that makes Amerus personal sits inside your machine. The outside world is a door you open on purpose.
Amerus is not a cloud AI with an offline mode.
It is personal AI designed to live locally.
Local at its core
Your AI. Your information.
On your device.
Bring your intelligence home. Download Amerus and keep what’s personal where it belongs.
For Mac (Apple silicon, macOS 14+) and Windows 11. No account required.
