Give it a brain

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

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.

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.

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.

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.

Skills library

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

Runs on a schedule

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