Claude Duet vs Meta Muse vs OpenAI Dots: 2026 Review

Chatbots wait for you to ask. The newest generation of AI doesn't. In the last six weeks, three "always-on" AI agents have launched — Meta's Muse, OpenAI's Dots, and now Anthropic's Claude Duet — and they all promise the same thing: an assistant that keeps working in the background, checks your apps, and pings you only when something needs your decision.

Should you turn one on? The honest answer is more complicated than the launch videos suggest. All three are still in limited rollouts, all of them need deep access to your email, calendar and apps to be useful, and none of them has been independently tested at scale yet. This comparison sticks to what the companies have actually announced and what reputable reporting confirms — and flags what we still don't know.

The short version: do you even need an always-on agent?

Before comparing features, ask the question the marketing skips. A regular chatbot answers when you prompt it and stops. An always-on agent continues working between conversations — drafting replies, watching for events, preparing work overnight — which is powerful but also costs you something: background activity consumes your plan's usage limits, and handing an AI standing access to your accounts is a privacy decision you can't undo.

If your AI use is occasional questions, our ChatGPT vs Gemini vs Claude comparison covers the chatbot world just fine. An always-on agent earns its keep when you have ongoing missions — a project to track, an inbox to triage, recurring briefs to prepare. Otherwise, "turn it on later" is a perfectly good answer.

Claude Duet: the work secretary (newest, most limited)

Anthropic's Duet, announced October 21, is positioned for professionals and small business owners. Its signature feature is a morning brief — it reviews your connected email and calendar, flags what needs attention, and starts drafting next steps. Through the day it re-checks every few hours and messages you when a task finishes or needs a decision.

Duet talks like a teammate (text or voice) in one ongoing thread, carries over your existing Claude memory, skills and connected apps, and can take on bigger jobs: dashboards, financial or sales forecasts, slide decks, prototypes and web apps. It connects to more than 6,000 tools and plugins via the Claude Marketplace, including Gmail, Slack, QuickBooks, Stripe, LinkedIn, DocuSign, HubSpot, Shopify and Canva.

The catches: it's a research preview on a US-only waitlist for Pro and Max subscribers — Team and Enterprise plans are excluded. It runs in its own subscription: Duet is included in your Pro or Max plan during the preview, but background checks and larger tasks consume the same usage limits as the rest of your Claude plan, which could run down your allowance faster than you expect.

On safety, Anthropic says an automatic classifier approves the agent's actions, screens messages for sensitive information leaks, and double-checks with you before important actions. Sending messages, making payments, signing documents and deleting data all require your explicit approval — and Duet has one hard line competitors don't: it cannot trade securities or transfer money between accounts, even with your permission. Purchases through Link and Shop Pay are possible but need approval, and Anthropic says Duet has no direct access to passwords or sign-in tokens.

Best fit: professionals and small business owners already paying for Claude Pro or Max who want inbox-and-calendar triage done quietly in the background.

Meta Muse: the free consumer agent with 10 million setups

Muse is the furthest along. Launched September 8, 2026 in the US (Canada followed September 18), it runs on Meta's Muse Spark models — the family Meta trains for long, multi-step tasks — and works across iOS, Android, the web, a Mac app, and even inside WhatsApp. It plans and completes multi-step tasks: researching options, comparing prices, booking travel, filling forms, sending emails (after your approval).

The scale is the story here. Meta's CEO said during the October 21 earnings call that more than 10 million people in the US and Canada have set up Muse in about six weeks — more than double what Threads had at a comparable stage — with roughly a quarter using it daily. The most common use case is shopping, with an average purchase above $200, which explains why Meta added travel booking (including a Klook partnership in Japan covering 426,000 experiences) and is expanding into small business tools.

The trade-off is the business model. Muse is free for consumers right now; Meta says paid subscriptions will cover heavier use, advanced models and business features, and it expects businesses to pay fees on transactions Muse facilitates. A small-business version added September 29 connects Facebook Pages, Meta ad accounts, Instagram professional analytics, Shopify and QuickBooks, with owners approving anything that publishes, sends or spends — and Meta says owners can inspect the agent's activity. Meta has also announced plans to bring Muse to its AI glasses.

Best fit: everyday users in the US or Canada who want a free, capable personal agent — especially for shopping, travel and routine tasks — without paying for a chatbot subscription first.

OpenAI Dots: the developer-flavored agent for ChatGPT power users

OpenAI's Dots, announced at DevDay on September 29, are the closest to a "team of agents" vision. You start with a primary dot, give it a name, and over time OpenAI envisions teams of dots working together on your behalf. Each dot runs on GPT-6 Astra with its own cloud computer and browser, reaches 4,000+ apps through the plugin ecosystem, and — unusually — you can talk to it through ChatGPT, Slack, Teams or voice calls, with texting support coming.

Dots are built for ongoing responsibility: monitoring customer feedback and preparing bug fixes for review, re-running analyses as new data arrives, keeping launch materials current. You can open your dot's "computer" any time to watch what it's doing, and even connect it to your own PC to work alongside you (opt-in).

Access is tiered: Pro, Business Premium and Enterprise plans in select markets, with the first dot included at no extra cost. OpenAI says conversations with a dot don't count toward ChatGPT usage limits, but the tasks it runs do draw on plan allowances. Dots follow ChatGPT's permissions plus custom rules for what needs approval, and OpenAI's docs describe mandatory human takeover for passwords and money transfers. For organizations, OpenAI is working with Microsoft on Agent 365 governance integration and previewing "specialist dots" with their own identities and credentials.

One privacy detail worth knowing, from OpenAI's own safety FAQ: disconnecting an app stops new access but doesn't delete information the dot already absorbed, and you currently can't inspect or edit individual memories directly — deleting the dot wipes its context, but files it created remain stored.

Best fit: heavy ChatGPT users on Pro or Business plans — especially developers, researchers and product teams — who want agents embedded in tools they already use.

The safety question nobody should skip

All three companies promise approval gates, but the designs differ. Duet uses an automatic classifier plus a hard block on money movement; Dots use layered custom rules with mandatory human takeover for passwords and transfers; Muse seeks confirmation before sensitive actions and shows its activity log. What none of them solves is the fundamental trade: a background agent with your email and calendar is a much bigger attack surface than a chatbot. Independent researchers have already shown that AI agents visiting websites can be hijacked, so treat approval prompts as your last line of defense, not a formality — and don't connect accounts you can't afford to have read.

The verdict: who should turn one on?

There's no hands-on winner yet — all three are too new and too limited for independent testing, and any review claiming otherwise is guessing. Here's an honest decision guide based on what's actually available:

• Already pay for Claude Pro/Max (US)? Join the Duet waitlist if inbox triage is your bottleneck. Watch your usage limits.
• Already pay for ChatGPT Pro/Business? Try your included dot for ongoing work projects — especially coding, research and ops workflows.
• In the US or Canada and pay for nothing? Muse is the obvious free starting point for everyday tasks and shopping.
• Everyone else: wait. These are all region-limited, waitlisted, or plan-gated. The category will look very different — and much more testable — in six months.

A note on how this comparison was made: none of these agents is publicly available for hands-on review yet, so there are no fabricated "we tested it" verdicts here.
