Straight answers.

No. Amerus is designed to run its AI locally on your device. Your Amerus conversations and information are not sent to an outside AI model. Information leaves only when you intentionally use a feature that sends, shares or retrieves something outside your computer.

Yes. Amerus’s local AI, Memory, Vault, documents and locally stored knowledge are designed to work without an internet connection. Internet access is needed only for things that require the outside world, such as retrieving online information or using connected services.

That is a central reason Amerus is local. Your personal information stays on your device rather than being sent to an outside AI model, making Amerus designed for personal, business and other sensitive matters.

Amerus lives on your device, so your personal intelligence goes where your computer goes. It remains available online or offline, as long as your device has power.

Amerus is free for 30 days. After that it is a one-time purchase of $199 and the licence does not expire — there is no monthly subscription and no annual fee required. Your purchase includes 12 months of every new feature and upgrade released in that time.

Your Amerus keeps working, exactly as it is. If you want to keep receiving new features, improved AI models and major new versions, Amerus Upgrades is $59 a year — and it is completely optional. If you don’t renew, nothing shuts off. You can always upgrade again later.

No. You buy Amerus once. The optional $59/year Amerus Upgrades plan is the only recurring thing on offer, and stopping it does not disable the software you own.

Yes. We’ll email you as your 30-day trial nears its end so it doesn’t lapse by surprise, and you can buy at any point before or after that. The reminder is based on when you registered — your actual trial clock runs on your own Mac, where we can’t see it — so treat the date as close, not exact.

You can pay by card whenever you choose to buy, through a secure checkout on this site — but nothing is collected to download Amerus or to run the 30-day trial. Payment is a deliberate step you take, not something that happens to you: no card is kept on file and nothing is ever charged automatically. Your key arrives by email as soon as the payment clears.

Registration gives Amerus LLC the name and email needed to send your download, service and security notices, and a reminder as your trial nears its end. It also records your acceptance of the Terms of Use and Privacy Policy. That information is Amerus Business Information, not User Content — nothing you later do inside Amerus is sent back.

New Amerus products, services or specialized editions that are separate from the Amerus you purchased may be offered separately and may have their own pricing. But improvements to your Amerus — new features, capabilities, AI models and major versions — are included while your upgrade coverage is active.

The same Amerus: the same local AI, Vault, Memory, Chat and licence — one purchase covers both, and a Vault exported on one can be imported on the other. The difference is in Connections. A few draw on things that only exist on a Mac — Apple Notes, Apple Calendar, Apple Reminders and Safari bookmarks — so those don’t appear on Windows. Everything else is available on both.

Amerus runs on Mac and on Windows. On a Mac you need an Apple silicon chip — M1, M2, M3, M4 or later — running macOS 14 Sonoma or later; that covers every MacBook Air and Mac mini from 2020, the MacBook Pro from 2020–2021, the 24-inch iMac from 2021, and every Mac Studio and Apple silicon Mac Pro. Intel Macs are not supported. On Windows you need a 64-bit PC running Windows 11; a dedicated NVIDIA graphics card makes the larger models faster but isn’t required. Windows 10 hasn’t been tested.

8 GB of memory works; 16 GB is recommended and lets Amerus run a stronger model. Allow about 6 GB of free disk space for the application, the AI engine and the models, plus room for whatever you add to the Vault. Full detail is on the System Requirements page.

No. There is no Amerus account to create and no sign-in to an Amerus service. You install it on your computer and it is yours.

In a folder on your own computer, alongside the app’s database. Documents, memories and conversations are encrypted at rest. Files you connect from elsewhere on your computer or in iCloud Drive stay exactly where they already were — Amerus indexes them in place and never moves or copies them.

Available now: folders on your computer, iCloud Drive, Obsidian vaults, and an Apple Health export from your iPhone — plus, on a Mac, Apple Notes, Apple Calendar, Apple Reminders and Safari bookmarks. Coming soon (built, awaiting each provider’s approval of Amerus as an app): Google Drive, Gmail, Dropbox, Microsoft personal accounts, Oura and Whoop. Later: Microsoft 365 work accounts and Notion. Each is a separate Connection you set up deliberately, and you choose what it syncs.

Yes. One installation supports several profiles, each with its own conversations, memories and documents, optionally protected by a PIN. Amerus always opens at a profile picker, and a document can be private, shared with specific profiles, or available to everyone on that computer.

You add documents to the Vault or connect a folder, and Amerus reads and indexes them locally so it can search and reason across them. When it answers, it can cite the source — click a citation and the document opens at the page or paragraph the answer came from.

Yes. Amerus can export everything — documents, memories and conversations — into a single password-protected file, and import it on the new machine. You set the password, and only that password can open it.

Yes, at any time. Individual memories, individual documents, whole conversations or an entire profile can be removed. Excluding a connected file stops Amerus using it without touching the original file.

No. It is personal AI designed to live locally. Online Connections extend what Amerus can reach; they do not define where Amerus lives.
