Atlantis

A house for your AI agents. Each one lives in a folder of its own, works with tools that stay inside it, and joins the others when you ask the room.

macOS · Apple Silicon and Intel

What it does

A roster, a house and a workshop

Atlantis keeps a roster of agents on your Mac. You talk to one at a time or to all of them at once, and you can watch them go about their day.

Agents

Every agent has a home

An agent is a folder with a SOUL.md at its root. Make one in the app or import a folder you already have. Edit the file and the agent changes with it, down to which tools it is allowed.

Oracle

A house you walk through

Agents sit at a desk while they work, head to the kitchen after a lot of tokens and to the game room when they are bored. You walk among them in 3D.

Garage

Ask the whole room

A group chat with the roster. Name an agent with @ or ask everyone. When several take it, they debate in rounds until most of them agree.

Armory

Tools that stay inside

Read, write and edit files, search them, fetch a page, download a file and search the web. Every path is checked against the agent's home first.

Skills

Skills, written or installed

Write a skill in the app or install one from AgentHub. An agent is told its skills on every turn and reads the one a task needs.

Akashic Records

A logbook that keeps everything

Every turn, tool call and notification, filtered by level and kind, kept until you clear it. Agents can send you a notification when a long task finishes or a decision is waiting on you.

Tron

Settings that explain themselves

Providers and models, a Storage tab that says what is using the disk, and Dr. House, which checks the app itself and says what is wrong.

How it behaves

Your Mac, your keys, your folders

Questions

Before you ask

What does Atlantis need to run?

A Mac, Apple Silicon or Intel, and a model to talk to. Atlantis speaks to hosted models, so it needs an Ollama Cloud key or an endpoint you add by hand.

What is an agent here?

A folder with a SOUL.md at its root. The file says who the agent is, what it is for and which tools it should not use, and the agent is told all of it on every turn. Skills live beside it in the same folder.

Can an agent touch files outside its folder?

No. Every path a tool is given is resolved against the agent's home, through symlinks too, and a path that lands outside is refused. Nothing under .git is written, and no tool runs a command.

Where are my keys and my data kept?

Keys are in the macOS keychain. The roster, settings, conversations and logbook are in the app's data folder on your Mac. The Storage tab in Tron shows each part and can clean it.

Does Atlantis send anything about me anywhere?

No. It talks to the model provider you set up, and to the web only when an agent's tool fetches a page or a file, or a link in a message is drawn as a card.

macOS says it cannot open Atlantis. What now?

Open System Settings, then Privacy and Security, and press Open Anyway beside the message about Atlantis. It is needed once, the first time the app is opened.

Is it free?

Yes. No account, no subscription and no tiers. You pay your model provider for what you use.
