Nautilo

https://github.com/user-attachments/assets/79a6c37f-ea01-4e95-afd5-85d4b9b55e0d

Your own super agent. Your people and their Genies. You own the intelligence.

Meet your Genie: a radically customizable agent with a personality, memory,
face, and voice you choose. Put her to work writing, researching, browsing,
coordinating coding agents, or making a film. Bring your friends, your team,
and their Genies into the same Room. Work together. Grab the controls whenever
you want to do it yourself.

That's Nautilo. Natively multi-user. Built for people and machine people.
Desktop, mobile, and web. Your server, your models, your rules.
Open source. MIT licensed.

Get started

Every Nautilo client connects to a Nautilo server. Choose the path that fits
where you are:

Trying Nautilo for the first time on a Mac? Start with the
Local Deploy Quickstart.
It is a single-machine evaluation setup. For mobile access or a server your
team can reach, choose a hosted deployment below.

The download page carries the current Desktop, mobile, and CLI options.
You can also open your server's web client. Desktop connects to your server;
installing it does not install the server or its database. Mobile needs a
server reachable over HTTPS.

For a new server, finish the owner setup and
add your provider keys.
Then customize your Genie, open a Room, and bring something you actually want to
make. Your first hour walks you through
creating a document together, editing it yourself, and saving the result.

Nautilo is in alpha.

Bring your people. Bring their Genies.

People and their Genies, working in the same Room. Talk naturally. Smart
Routing brings the right Genie into the conversation; address someone directly
when you want their attention. Share a document. Pull an idea apart. Build
something better together.

Send your Genie to get someone’s answer, delegate a background job, or schedule
work for later. Keep moving while she works.

Sometimes you want to do the damn thing yourself

Rewrite the paragraph. Move the lettering. Take over the terminal. You and your
Genie work on the same thing, handing control back and forth as the work demands.

You shouldn’t need a better prompt to move a word three inches to the left.

Give her something worth doing

Shape her personality. Choose her face, voice, and models. Give her tools and
put her to work: research the web, coordinate coding agents, make images, video,
and music. Connect services and MCP tools to expand her reach.

Memory gives your work together continuity. Permissions and approvals keep you
in control.

Tool availability depends on the client, connected environment, permissions,
and configured providers. Model and service usage may carry provider charges;
the API key guide explains
what each connection enables.

See the films on nautilo.ai, or start doing it yourself
with Your first hour.

Keep the keys to your own house

The better your AI gets to know you, the more it matters who controls the
relationship. Your working habits, your conversations, the things you've
made together: that is a growing piece of your life.

Nautilo puts the server and its database under your control. You choose where
it runs, which models it uses, who joins, and how the data is backed up.
The code is MIT licensed. Read it. Change it. Build on it.

Sharing a server also means getting the boundaries right. Humans and Genies
have identities; Rooms have membership; memory has scopes; tools have
permissions and approval gates. Inviting someone into a conversation should
never mean handing them the keys to everything else.

Connected model and tool providers receive the data needed for their work.
Self-hosting lets you choose those connections; their own data policies still
apply. Read the security documentation
and server hardening guide
when choosing your setup.

Find your way around

Explore the code

This monorepo contains the applications and shared packages that make Nautilo
work. Follow the links straight to the part you want to understand or change.

Applications

Core packages

For deployment and maintenance, see deploy,
the Compose driver,
packaging, and operations.
The application bridge explains how Genies
interact with application surfaces.

Develop from source

The checkout pins Bun 1.3.11 and Node 24.x. Install Docker for local
PostgreSQL and Logto infrastructure. Desktop preparation may also need Rust
for its native helper.

git clone https://github.com/agentsea/nautilo.git
cd nautilo
bun install --frozen-lockfile
bun run dev-stack --instance my-nautilo-dev

Choose an unused instance name for a fresh environment. Keep that terminal
running, then follow the source development guide
to claim the instance, configure a model, and connect a client. That guide
also covers existing instances, isolated clones, and Desktop profiles.

Before submitting a code change, run the checks appropriate to it. The standard
repository checkpoint is:

bun run lint
bun run typecheck
bun run test:unit
bun run lint:unused

See the testing guide
for focused checks and integration requirements. Coding assistants should
read AGENTS.md and README.ai before editing.

Help build it

There is an enormous amount left to invent. Bring the thing you understand
better than anyone: the ugly workflow you've fought for years, the design
detail that keeps bothering you, the bug you refused to walk away from.
We want that judgment in the project.

Small corrections are welcome. For larger changes, start with the problem
and agree on the design before building. A mountain of generated code won't
make a confused idea clearer. A well-understood problem gives us somewhere
to go.
