Chat, tasks, and routines
Talk to your teammates like colleagues. Give them tasks they follow through on, and routines that run on a schedule.
Beta preview
Your own team.
On your terms.
AI teammates that live on your hardware.
Your agents run on a box you own. Give a teammate a browser you can watch — and take over any time. Important actions wait for your decision, or follow the rules you set.
Beta access starts with your email. We send a six-digit code, then you can download the desktop app for macOS on Apple silicon.
Interactive demo · fictional data
See your teammates at work
Two jobs. One box. You stay in control.
A simulated workflow, not a live session. No accounts are connected and no messages or payments are sent.
How it works
Three steps to a crew
Get beta access
Confirm your email with a six-digit code, then download the desktop app for macOS on Apple silicon. An account is optional: it links your box to the relay and holds Pro and included model access.
Connect your box
Put Nyx on a Mac with the desktop app, or on hardware of your own that stays on. Your teammates live there, not on our servers.
Put your teammates to work
Chat with them, hand over tasks, and set routines. They work; you watch, approve, and take over when it matters.
What they do
A team, not a chat window
Watch the work happen
Give a teammate a browser you can watch live — and take over the moment you want the controls.
Approvals, rules, and pause
Important actions wait for your decision. Rules cover the routine, and one switch pauses everything.
Your control
Your box, your rules
Your conversations stay on your box
Threads, tasks, and rules are stored on your hardware — not on our servers.
The model sees what it needs
When a teammate answers, the content needed for that answer goes to the model provider you chose. Included access goes through a hosted model gateway.
You stay in charge
Approvals for what matters, rules for the routine, pause for everything. You choose which actions need you.

Questions
Asked often
What hardware do I need?
A Mac running the desktop app, or a computer of your own that can stay on. The box is yours: agents, storage, and rules all live on it.
Which models do the agents use?
The ones you choose. Sign in with a ChatGPT subscription or bring your own API keys; we do not mark up tokens. Nyx Auto is also included with your account: 100 requests per account per day, through a hosted model gateway. A single task can make several requests.
What does the beta include?
The desktop app for macOS on Apple silicon, from the beta page once you confirm your email. If no build is published yet, the download sends you back to that page. An account is optional and adds Pro and Nyx Auto.
What does it cost?
Free to self-host. Pro is $12 a month or $120 a year, billed through Stripe. Team and Managed Box come later. The iPhone app bills through the App Store.
Who can see my conversations?
Conversations are stored on your box. When an agent answers, the content needed for that answer goes to your chosen model provider — or, with included access, through the hosted model gateway.
How do updates work?
The box checks for updates automatically. Downloading and installing always wait for your consent.
