Amerus
The difference
Nothing is sent to an outside AI model.
Nothing becomes part of someone else’s AI. Nothing leaves your computer unless you choose to send or share it. Use Amerus for everything — including the things you’d never trust to an ordinary cloud AI service.
Why Amerus
Personal. Private. Always Ready.
It actually knows you
Amerus knows the information you give it, remembers what matters, and brings your documents, knowledge and personal context together in one place.
What’s yours stays yours
Your conversations and information stay securely on your computer rather than being sent to an outside AI model — or added to someone else’s system.
It goes where you go
Amerus goes where your device goes. Online or offline, its local intelligence, Memory, Vault and stored knowledge remain with you.
What you can finally ask an AI
The things you’d never paste into a cloud chatbot.
Because your information stays on your machine, Amerus is designed for the matters that are actually personal.
Inside Amerus
One place for your intelligence.
Four parts, working together on your own machine.
Chat that answers from your own documents
Ask a question in plain language and Amerus answers using what you’ve actually given it. Every answer can cite its source — click a citation and the document opens at the exact page or paragraph the answer came from.
- Choose Fast, Balanced or Deep for the question at hand
- Print or share any conversation
A Vault for everything worth keeping
Contracts, statements, manuals, records, research. Add documents to the Vault and Amerus can read, search and reason across all of them — while the files themselves stay on your Mac.
- Search by name, tag or category
- Built-in previewer for PDFs, spreadsheets and more
Memory that holds on to what matters
Tell Amerus something once — a preference, a deadline, a detail about your work or your family — and it keeps it. Your context builds over time instead of starting over with every conversation.
- Review, edit or remove any memory yourself
- Separate profiles for everyone in the household or office
Connections you choose, one at a time
Bring in the information you already have — folders on your Mac, iCloud Drive, Google Drive, Gmail, an Apple Health export. You pick each connection, you pick what syncs, and you can exclude anything or turn it off at any time.
- Connected files stay where they already are — nothing is moved
- Excluding a file stops Amerus using it, without deleting it
Local at its core. Connected when useful.
Amerus is not a cloud AI with an offline mode.
It is personal AI designed to live locally. Online Connections extend what Amerus can reach; they do not define where Amerus lives.
You decide when the door opens — and it stays shut until you do.
“Amerus doesn’t simply promise to treat your information carefully.
It is designed to keep it with you in the first place.”
Private by where it lives
Always Ready
The internet adds to Amerus. It isn’t where Amerus lives.
Because Amerus lives on your computer, it doesn’t need an internet connection to be Amerus.
- Talk to Amerus
- Ask about your documents
- Use your Vault
- Access Memory
- Search the information you’ve stored
- Use its local intelligence
An internet connection is needed only when you specifically want something from the outside world — retrieving information you’ve stored online, synchronizing a connected service, or accessing current internet information.
About Amerus
Personal AI should actually be personal.
Amerus was created around a simple idea: your intelligence and information should live with you, remain under your control, and be available when you need them — not depend on sending your private life to someone else’s AI.
Amerus combines local intelligence with your Memory, Vault, documents and authorized Connections to create a personal AI designed around you, while keeping its core on your own device.
That is the whole idea, and it is the reason Amerus is built the way it is.

What it costs
Try it free. Buy it once. Keep it.
Most AI services require you to keep paying every month. Amerus is different. Free for 30 days, then a one-time purchase of $199 — and your licence doesn’t expire. Staying current afterwards is optional, at $59 a year, and if you skip it nothing shuts off.
No credit card is collected. Amerus LLC sends one invoice when your trial ends.
