| Who works for you | A standing team of named specialists built around your life: a Chief of Staff for your job, a Business Operator, a Family Steward, a Researcher and more, each with a defined role and coordinated by your primary operator. | In beta: named Bots you create, each with one primary job such as inbox, expenses or recruiting; they can coordinate with each other in group chats. | Your dot: one always-on agent, rolling out gradually to eligible plans, with the option to add more dots announced for the future. | One personal agent, Muse, rolling out in the US, that turns your goals into a plan and advances the work on its own. | One assistant: a completely reimagined version of Siri, built on Apple Intelligence and rolling out in beta. | Copilot, plus Autopilots in private preview: always-on agents with their own identity, such as Scout, which works across your Microsoft 365 apps. |
|---|
| Models | Several providers. Models are chosen per task by capability and risk, higher-risk work can be reviewed by a second model, and any model can be replaced without losing your context. | An xAI agent platform. xAI’s launch materials do not describe a choice of model provider. | Powered by GPT-6 Astra, OpenAI’s own model. | Powered by Muse Spark, Meta’s own model, built for agentic work. | Apple Foundation Models, custom-built in collaboration with Google and its Gemini models, on device and in Private Cloud Compute. | Auto routing weighs accuracy, speed and cost to send each request to the model best suited for the job. |
|---|
| Memory and knowledge | Maintained knowledge with its sources and provenance, held as your asset outside any single model, so it survives every change of model, device or interface. | Each Bot keeps its own memory of working preferences, important facts and summaries of its prior work. | Draws on your ChatGPT memories and creates its own, including from connected apps. | Remembers what matters to you, learns from conversations, and forgets what you ask it to. | Personal context understanding across your messages, emails, photos and more. Siri Recap, summaries of conversations to review later, is announced for beta in late 2026 and requires Apple Watch Series 12 or Ultra 4 with a supported iPhone. | Builds context through Work IQ, learning how you work; an Autopilot (in preview) has its own memory inside your organisation’s tenant. |
|---|
| Authority and accountability | Authority governed by identity, source, policy and risk. Consequential actions come to you first, autonomy is earned domain by domain, and actions leave an auditable record. | Approval prompts for sensitive actions (allow once, always allow, or deny), with saved rules and admin policies for teams. | Asks for approval before sensitive actions; for the most sensitive, such as moving money, you take over yourself. | Checks with you before sensitive actions such as sending an email or making a purchase; you choose each app’s access. | Carries out systemwide app actions you ask for, such as drafting an email or editing and sharing a set of photos. | For its preview agents, sensitive actions can require a human sign-off, with a governed Entra identity, Purview data protection, audit, and admin controls in Agent 365. |
|---|
| Channels and continuity | Each specialist keeps one conversation that continues across Telegram, the Staff web workspace and Staff Control. Reply where you are; the context follows. | Desktop and mobile apps, and Slack for team Bots. | ChatGPT, Slack and Microsoft Teams. | The Muse app and WhatsApp, with AI glasses announced as coming soon. | On Apple devices, from the side button, the Dynamic Island, Spotlight and context menus, with actions in apps such as WhatsApp; Microsoft Outlook is announced as coming soon. | Word, Excel and PowerPoint built into Copilot now; Autopilot, in private preview, shows up in Teams, Outlook, chats, channels and documents. |
|---|
| Distribution and lock-in | Not bundled into a device, an app or an employer. The same governed operator follows you from channel to channel, and is designed to reach more of them; the relationship and the context stay yours. | Reaches people through xAI’s own Grok apps and on X, where you can tag @bot to start work where available. | Built into ChatGPT and rolling out with its Pro and Business Premium plans, so it reaches the people already using ChatGPT. | Available directly in WhatsApp, Meta’s messaging app, and free for most of what people need. | Built into iPhone, iPad, Mac and Apple Vision Pro: the operator arrives with the device. | Built into Microsoft 365, so it reaches people through the work tools their employer already provides. |
|---|
| Your data and boundaries | Business, employment and private sources keep separate identity, memory and policy boundaries. Each employer’s confidential material stays isolated, while what Staff learns about how you work carries across. | Your Bots share one cloud computer, with its files and signed-in sessions; xAI advises not to treat separate Bots as a security boundary. | Each dot works from its own cloud computer, building on ChatGPT’s protections, within boundaries you set. | Agent and personal data are housed together in Muse Secure VM; credentials go into secure storage, used without Muse seeing them. | Runs on device or in Private Cloud Compute, where Apple says personal data is not stored nor made accessible to Apple or anyone else. | Lives in your organisation’s tenant, under its data protection policies and IT administration. |
