01 — A brain

Give it a brain

A local LLM that never leaves your machine, or bring your own key.

Ollama LM Studio Jan Claude Code OpenAI Codex

Make it yours

Give it a face of its own — customise however you wish.

Build an agent in three steps: choose a brain (local LLM, Claude Code, OpenAI Codex, OpenRouter and more); connect every channel (WhatsApp, Instagram, Email, phone calls and 17 more); then give it a custom face. Security features (encrypted vault, isolated public agent, on-device channels) are detailed in the feature grid below.

your crew · one agent per context

Don't build one agent. Build a crew.

One for work, one for your projects, one for home — each a fully separate agent with its own brain, its own memory, its own people. Switch between them in a click; nothing crosses over.

Cody

work

Claude Code · work plan

Knows your team — who does what — and pings the right person on Slack when a release is ready.

Nova

projects

Ollama · local & free

Keeps your side-project world — repos, ideas, drafts — in its own head, never your work agent's.

Juno

home

Gemini · its own key

Knows the family — and how each person prefers to be reached, from WhatsApp to a phone call.

Its own brain

Pick per agent: a local model that never leaves the machine, your Claude subscription, Codex, OpenRouter, Gemini, or any key. Two Claude plans? Pool them on one agent and let it rotate.

Its own memory & files

Each agent has a separate workspace, knowledge, and context. What your work agent learns never bleeds into your home agent — and vice versa.

Its own people & channels

Every agent keeps its own contact book — who your teammates are, what they do, and how to reach them: Signal, WhatsApp, Instagram, email, a call. Its channels are its own too.

A face for every agent

Each agent wears its own pixel-art face — so you always know who you're talking to, and switch between them at a glance: in the app, at the notch, on every device.

the notch · macOS

Your agents live at the top of your screen.

No window to find. Everything an agent needs from you — and everything you need from it — happens at the notch, without leaving what you're doing.

skills × channels

An agent for any situation.

Every skill can meet every channel — so the same building blocks become a support desk, a social team, or a night-shift operator. Agents that really work for you, not demos.

Support agent

Answers customers where they already write — web chat, email, WhatsApp, Instagram — from your own docs and knowledge. Escalates to a human the moment it should, and you approve anything sensitive before it goes out.

Social media manager

Drafts, schedules, and posts across Instagram, X, TikTok, LinkedIn, Facebook and more — in your voice, on your calendar. Every post can wait for your approval at the notch before it publishes.

Ops on your servers

Watches logs, fixes what's wrong or reports first, runs the nightly chores — 24/7 on the box. See the remote fleet →

Meeting notetaker

Transcribes on-device, listens for your name, and writes the minutes. See meetings →

Anything on a schedule

Standing tasks on any agent: a morning brief, a weekly report, an inbox sweep — it runs while you don't.

Mobile dev buddy

Boots an iOS Simulator or Android emulator right in the panel — or drives the real Android phone on your desk — taps through your build, and screenshots or records a repro into files. On real hardware the agent is look-only until you say otherwise. Point it at servers to build over SSH and watch the running app in your own browser.

Terminal in the session

A real shell right under the chat — on your machine or on a remote server over SSH — with tabs for several at once and command autocomplete as you type. Select any output to hand it straight to the agent as context.

19 channels · every skill on every agent · approvals before anything public goes out

everything it does

Everything you need, out of the box.

Auto-rotate your subscriptions

More than one Claude Code plan? A Codex one too? Pool them per agent: when an account hits its usage limit the agent switches to the next — and can fall back to the other CLI — mid-task, without dropping anything.

Remote control

Run the engine anywhere — a Linux box, a Windows machine, a server — and drive it from your browser, your phone, or your Mac. Every device pairs with a code you approve.

Encrypted vault

Keys sealed with AES-256-GCM. Write-only: agents see key names, never values.

Isolated public agent

Strangers talk to a sandboxed twin, walled off from your files and secrets.

One fleet

Link agents on other machines and use them like they were local. Share an agent with a URL. The remote fleet →

On-device channels

Signal and iMessage run on your own machine — no middleman between you and your messages.

Lives in the notch

Dispatch, replies, approvals, questions, files, voice — at the top of your Mac's screen.

Meetings & voice

Live meeting capture with streamed transcription, plus realtime voice conversations. All meeting features →

Skills library

Install curated skills in one click — or ask an agent to write its own. Browse skills →

Runs on a schedule

Cron jobs, one-time runs, and one command dispatched to many agents at once.
