## The agents aren't the bottleneck anymore. You are.

One agent per terminal means babysitting one task at a time. Run several by hand and they collide — same files, same branch, same working directory.

Nucleic gives every session its own real git worktree and branch. As many agents as you want, zero collisions — each one reviewed, merged, and shipped automatically.

The Nucleic cockpit — the Control panel open over a project's chats. Illustrative.Nucleic on iPhone — watch, steer, and ship from anywhere. Illustrative.
What it does

## Parallel by design. Safe by default.

Isolation, attention, and trust — the three hard parts of running a fleet. Solved by design.

01

### Autoship

Work that's done ships itself. Finished sessions merge automatically — queued per branch, conflict-aware, never mid-task. On Nucleic Control projects.

02

### Nucleic Control

Your repo, cloned and sandboxed. Nucleic watches git directly, so agents stay contained — and unattended work runs on ground Nucleic commands.

03

### Antimatter Mesh

Your Macs, cloud runners, and iPhones become one machine. A custom network layer stitches every device into a single surface — so an agent running anywhere feels like it's running right in your hands.

04

### Orchestra

One frontier model conducts. A fleet of leaner workers plays in parallel — Fable 5 orchestrating, Sonnet 5 doing the heavy lifting. Frontier-grade thoroughness, at a fraction of the cost.

05

### Work from your iPhone

The cockpit, in your pocket. Watch sessions, answer approvals, and steer work from wherever you are — end-to-end encrypted.

06

### Agent-agnostic

Claude Code, Codex, and Grok Build behind one approval flow. Plus any agent that speaks ACP, the open Agent Client Protocol.

Built on containers & virtual machines

## The right machine for the job, summoned on demand.

When an agent needs somewhere safe to work, Nucleic summons the right machine — a container for the quick stuff, a real Linux box for real dev work, a whole Mac when only a Mac will do. Each one walled off from yours. Free to install, run, and break anything inside. Gone the moment the work is done.

### Containers, for the quick stuff

A shell, a script, a one-off command. Nucleic drops it into a container that starts in an instant and vanishes just as fast. Real isolation, zero ceremony.

### A real Linux machine

When the job calls for a genuine kernel, a desktop, or root, the agent gets a full Linux VM of its own — real hardware underneath, not a corner of yours.

### A whole Mac of its own

For building an app or clicking through a live interface, the agent gets an entire macOS to itself — running under the hood, never touching the Mac in front of you.

Native to Apple platforms

## Made for the Mac. Every pixel of it.

No Electron. No web wrapper. Nucleic is 100% Swift and SwiftUI, with a native iPhone remote at its side. It looks, feels, and performs like it was born on your Mac — because it was.

### On-device intelligence

Apple Intelligence handles the local work — classifying turns, summarizing tool calls, triaging your idea inbox — privately, entirely on your Mac.

### Native sandboxing

Agents run in real, lightweight virtual machines — native to macOS, no daemons, nothing extra to install.

### macOS orchestration

Hand an agent a Mac of its own. Nucleic spins up an isolated macOS VM where it clicks, types, and runs apps — while yours stays untouched.

How your devices connect

## One fleet, wherever your devices are.

Every device running Nucleic finds the fastest path to the rest — the local network when they're side by side, your private tailnet when they're apart, a relay when nothing else reaches. Today your iPhone reaches your Mac. Tomorrow, every Nucleic node — Mac or iPhone — discovers and works with every other. End-to-end encrypted, on every path.

### Local network

On the same Wi‑Fi, devices discover each other over Bonjour and connect directly. No setup at all.

### Tailnet

Farther apart, they meet over your own Tailscale tailnet — private, direct, yours.

### Nucleic Private Relay

When nothing else connects, a zero-config relay does. End-to-end encrypted, always.
