Claude Duet vs ChatGPT Dots vs Meta Muse: Who Can Get Each and Which to Use

Muse is open to free users, Dots starts at $100, Duet needs an invite

The first four rows decide whether you can get each agent at all; the last four show how it works once you have it.

Read the "Where you message it" row with care: Duet connects to Slack as one of its apps, so it can read your Slack, but you message Duet itself only in its own app or on claude.ai. Dots is the only one of the three you can message from Slack, Teams or iMessage, and Muse the only one in WhatsApp.

Outside the US the choice narrows. Duet is US-only, Muse is announced only for the US and Singapore, and Dots on Pro excludes the EEA, Switzerland and the UK. Dots on Business Premium is offered in supported ChatGPT regions, subject to workspace eligibility; a Business workspace needs at least two Standard or Premium seats in total, and a Premium seat costs $100 a month billed annually or $125 billed monthly.

Claude Duet waitlist: what the form asks and who gets in

Join from the Claude Duet product page with "Join the waitlist". The form asks for your name, email address, Claude plan and phone type (iPhone or Android), with an optional note on what you do and what you would hand off first. Use the email address on your Claude account: Anthropic ties access to the address you give. Invitations go out in waves, joining guarantees no date, and Anthropic publishes no rule for who goes first beyond its launch scope, US Pro and Max subscribers. Using Duet takes all three: a Pro or Max plan, a US account and an invitation.

Once admitted, you get one full reset of both your five-hour and weekly Claude limits, usable until November 30, 2026. Duet is included with Pro and Max at no extra cost during the preview, and Anthropic says its features can change before the preview ends.

Claude Duet vs Muse: business accounts on a schedule, or tasks in a browser you share

Claude Duet runs on Claude Opus 5.5, which you cannot change, and carries over your memory, skills and connected apps from your Claude account. Anthropic aims it at professionals and small business owners: it lists more than 6,000 connectors and plugins, with QuickBooks, Stripe, Gusto, HubSpot and Shopify among the logos, and it can buy things for your business through Link or Shop Pay with a one-time card for each purchase. Each morning it sends a brief on what needs attention, then checks your accounts every few hours, so Anthropic warns that something urgent can arrive between checks. It does not call or text other people, and Anthropic says personal errands such as booking tickets are weaker. Anthropic's own pages disagree on Microsoft 365: the product page shows an Office 365 logo, while the support article says Microsoft 365 isn't available yet.

Meta pitches Muse to everyone, with a free tier. It answers questions, completes tasks, browses the web, makes purchases with a one-time card number, generates images and creates documents, and it keeps working in the background. You share its browser with it, where Duet's browser stays out of view. The Mac app can organize files, fill out forms and pull from Messages, Calendar and Notes with your permission. Meta also offers Muse for Small Business, a set of skills and connectors for owners.

ToolColumn's read: choose Duet when the work is your business's books, payments and inbox and you already pay for Claude in the US; choose Muse for personal tasks, for WhatsApp, or when Duet's waitlist or region keeps you out.

Dots vs Muse: ChatGPT, Codex and Slack, or WhatsApp and a Mac

A dot is an always-on agent inside ChatGPT, powered by GPT-6 Astra, that keeps making progress on ongoing work between conversations. It can start work in Codex and follow up on existing threads, set reminders and run recurring checks, and review your connected apps unprompted to form memories. You can open its cloud computer, take over and hand control back; access to your own computer is optional and starts turned off. The texting beta for US Pro users runs over iMessage or RCS through Linq, a third-party provider, sends proactive updates, and does not support group chats, calls or FaceTime. You can call your dot from the app, but it cannot call you, and it cannot have its own email address at launch.

ToolColumn's read: Dots fits if your projects already live in ChatGPT, Codex, Slack or Teams and you pay for Pro or Business Premium. At $100 a month or more against Muse's free tier, Dots is not the agent to buy only for errands; Muse is, as long as you are in the US or Singapore.

Duet spends Claude limits, Muse counts tokens, Dots usage terms are pending

• Claude Duet uses your plan's five-hour and weekly limits at the same rate as chat, and its background work, such as the morning brief and check-ins, counts too. Larger tasks like a financial model or a deck take more turns, so Anthropic warns you may reach your limits sooner than with chat alone. It publishes no Duet-specific behavior at the limit. Because Duet and your chats share one meter, a busy week for Duet leaves less Claude for everything else.
• ChatGPT Dots does not count conversations with your dot toward ChatGPT usage limits; deeper work draws on a separate allowance. OpenAI exempted dot usage from plan allowances for the month after the September 29 launch and said it would then share usage terms for each plan. OpenAI's help center and docs had not published those terms when ToolColumn checked on October 29, 2026, and they give no task count, no behavior at the limit and no price for extra dots.
• Meta Muse Free has a limit whose size and refresh Meta does not publish; at that limit you upgrade or wait. Power gives 500M Muse tokens a week for $20 a month and Maximum 3B for $100, with no top-ups listed. Meta says paid subscriptions are in limited testing and not available in all locations yet.

Grok Bot comes with The X Subscription, not these plans

Grok Bot, xAI's agent, comes with The X Subscription from the Premium tier at $30 a month rather than with any of the plans above; Grok Bot pricing and limits by plan covers its tiers, weekly pool and free trial.
