The One — AI agent teams on your own computer
Ask the main assistant in plain words. It answers what it can, opens a matter for bigger work and hands it to a working group of Agents. You judge what they deliver, and every change they make can be undone.

How it works
Three recordings straight from The One: a request becomes a matter, a working group delivers it, and every change it made can be put back.
Act 01 · Ask
Tell the main assistant what you want. It answers on the spot, or opens a matter that says where the work should get to and hands it to the working group made for it, in the same step. It asks you only what only you know.
Act 02 · Follow
Every matter is a board: what waits for you first, then progress, files and checks. The Theater shows each Agent thinking, calling a tool or waiting; Review shows every change it made. Accept, send it back with your words, or give up.
Act 03 · Control
Nothing waits for your approval. The action log records every file Agents change and every address they reach, keeps a copy before anything is overwritten or deleted, and puts it all back for one matter or for everything since a time.

Engineering ideas
Prolifera Engineering grows a running system at runtime; A-Genetic Engineering writes a working crew down as a reusable gene.
The assistant grows the system at runtime.
Prolifera Engineering is how The One builds a multi-agent system as it works — a human-facing chat agent that clones itself, creates agents from presets, stands up whole graphs, and tears them down, modeled on cell proliferation.
Instantiate a graph, or clone an agent — config, context, and tools — into a fresh identity. The copy is born disconnected and inactive.
One agent becomes several to parallelize bounded work. A long context does not divide an agent; it compresses its memory in place instead.
A created agent is a specialist because its prompt, profiles, skills, and tools are set at creation from its preset.
A finished agent reports up and is put to sleep; its resources are reclaimed only when a parent explicitly tears it down.
Honest by design: the framework only ever does two things on its own — compress an agent's memory, and sleep a finished one. Proliferation is the agent's own decision and is not globally capped, so it can run away; by default the authority sits in one agent, and the whole system stays observable and can be torn down — not prevented.
Read the docsThe crew's gene is a Graph template.
A working crew is written down in full — every agent's prompt, skills, tools, and the edges between them — as a reusable Graph template: the crew's gene. The built-in assistant designs, instantiates, and edits these genes conversationally.
A working-group template: its nodes, and edges whose text is the handoff — when, what to pass, what comes back.
Roles, each with its own instructions, model, built-in tools, MCP servers, Skills and Plugins.
The main assistant runs a template for a matter: a working group on that matter's board.
Copy, export or share the Space. Memory goes along when you choose; secrets never do.
A gene fixes structure, configuration and where experience lands, not the outcome: each run still depends on the model. Whether a change to a gene helps is settled by readings, never assumed.

Questions
The One is a desktop app for macOS and Windows by The Zeroth. You tell its main assistant what you need; anything bigger than one answer becomes a matter with its own board, and the assistant hands it to a working group of AI agents that does the work on your computer.
The desktop app runs on macOS 15 or later with Apple Silicon and on Windows (x64). On Linux servers (x86_64 and arm64), the-one-server runs the same agents without a screen and installs with one command.
Yes. The agents and their tools run on your Mac or PC and work with your files there. Model calls go to the model service you choose, and an agent reaches other services only through its tools. Every action is recorded in the action log, and files the agents changed or deleted can be put back.
Members get The Zeroth's official model service, powered through OpenRouter, with models from OpenAI, Anthropic, Google and others. You can also connect your own: OpenAI, Anthropic or Gemini API keys, OpenAI Codex through Sign in with ChatGPT, or any OpenAI-compatible endpoint.
Membership is $20, $60 or $200 a month (Starter, Pro and Max). Every plan has the same features and includes official model service usage. With your own model accounts, those providers bill you directly and no membership quota is used.
Software work in your own code projects, research and writing, websites, and recurring work such as daily reports. A working group is a team of agents defined as a Graph; you can change the ones that come with the app or build your own.
Yes. Schedules, webhooks and new mail, orders, files or pages can hand work to a matter's working group. What needs you waits under Needs you, and the morning report sums up what happened.
