Claude Duet vs Grok Bot vs Meta Muse: Which AI Agent Should Your Business Pick?

Three AI agents now compete for the small business owner's to-do list: Anthropic's Claude Duet, SpaceXAI's Grok Bot, and Meta's Muse. All three can do work on your behalf. They differ sharply in price, in how much they do without asking, and in who can get in the door today. This guide compares them on the points an owner cares about and picks a winner for each use case.

Disclosure: Claude Duet is made by Anthropic, the maker of the AI model that assists our editorial team. We have held it to the same standard as the others, using published sources only, and we flag where information is thin.

Quick verdict

• Best for owners who want control over every dollar: Claude Duet. Every payment, message and signature waits for your approval, and it is included in Claude Pro and Max.
• Best for a hands-off digital team, if you can pay for it: Grok Bot. It works in its own computer environment and can coordinate specialist bots, but it starts at $120 per seat per month.
• Best for owners on a zero budget who live in Meta's tools: Meta Muse. It is free to start, connects to Instagram, Facebook and Meta ad accounts, and sells more usage rather than more features.

If you have to choose one today, a typical owner with a modest budget and a lot of admin should look at Duet first if they already pay for Claude, and Muse first if they do not.

Claude Duet

What it does

Anthropic describes Duet as an app for small business owners and professionals that tracks what needs attention and follows through on delegated work. According to a TestingCatalog report, it sends a short morning brief based on your connected apps, checks those accounts every few hours, works on assigned tasks in the background, and asks before acting. It can schedule meetings, build dashboards and forecasts, and make prototypes or web apps. One ongoing text or voice thread covers quick requests and multi-week projects.

The money features come from Stripe. Through Stripe's Link agent wallet, Duet can buy items online, such as ads, office supplies or a team lunch, and each purchase requires your approval before it completes on a virtual card. Through the Stripe MCP server, it can send invoices and payment links, manage products and prices, review revenue and issue refunds.

What it can't do

• It must show proposed actions and wait for approval before sending messages, making payments, signing documents or deleting anything.
• Securities trading and transfers between accounts are prohibited.
• A classifier blocks sharing credit card numbers and government ID.
• It may misread threads or rank urgency poorly, personal errands are less developed, and you cannot yet view its browser.
• Background checks consume plan limits.

Price and access

No separate price is listed. Duet is included in Pro and Max plans and shares their usage limits. Access is by waitlist and limited to US Pro and Max subscribers during the preview.

Who it is for

The owner who wants an assistant that acts, but never spends or sends without a yes. It suits solo operators and small service businesses that invoice clients and buy supplies.

Grok Bot

What it does

VentureBeat reports that Grok Bot, released in early beta on August 11, 2026, gives each Bot its own computer environment, so it keeps working when your laptop is closed. It operates websites and apps through their interfaces, including those with no API. You can demonstrate a workflow once and it saves the workflow as a reusable routine. Bots can message each other and hand off tasks, with a Chief of Staff Bot coordinating specialists. Example roles include Sales Outbound, Talent Scout, Paid Media, Expense Manager and Account Health.

What it can't do, or hasn't proven

• SpaceXAI has not released agentic benchmarks.
• Model routing is automatic. You cannot choose or pin a model, and the underlying models are not named.
• VentureBeat notes that permissions, escalation rules and memory accuracy will determine reliability, and that usage limits could substantially affect the cost of continuously running agents.
• Android is listed as coming soon.

Price and access

Beta access goes to SuperGrok Heavy ($300 a month), Cursor Ultra ($200 a month for individuals) and Cursor Premium Teams ($120 per seat per month, with centralized billing and SSO) subscribers. Organizations wanting access now are directed to a waitlist. For a five-person team on the teams plan, that is $600 a month.

Who it is for

A business with real volume in sales, marketing or operations that is willing to pay for a persistent, multi-role team of bots and has someone to supervise them. For a one-person shop, it is likely more than you need.

Meta Muse

What it does

TechCrunch reported on September 29, 2026 that Meta is expanding Muse to small businesses, with the pitch that owners are "short on hours, not ideas." Muse connects to tools for sales, operations and marketing, and can link to Instagram professional account analytics, Facebook Pages and Meta ad accounts. Meta says it learns what a business sells, how its brand sounds and what customers ask about most. Listed integrations include Shopify, Slack, Asana, Canva, QuickBooks, Klaviyo, Notion, Stripe and Zoom.

What it can't do, or hasn't said

• TechCrunch does not say what Muse does on its own versus with your approval.
• One pricing tracker reports some limits that do not change by plan: one Gmail and one Outlook account per connector, per-action approval, and availability only in the US and Canada.
• When you run out of weekly usage, the agent pauses until the reset or until you upgrade.

Price and access

Meta says Muse is free with usage limits, with paid plans for more usage. Third-party tracker usecarly.com lists Free at 100 million weekly tokens, Power at $20 a month for 500 million, and Maximum at $100 a month for 3 billion, with the same features on every plan. Treat those paid figures as reported rather than confirmed by Meta in the TechCrunch story.

Who it is for

Owners who already run their marketing through Instagram, Facebook and Meta ads and want help at no cost to start.

Head to head: pricing

Muse wins on cost, because you can start free. Duet is next if you already pay for Claude Pro or Max, since it adds no separate fee. Grok Bot is the most expensive by a wide margin, at $120 per seat per month at the lowest tier we found. Watch usage limits on all three: Duet's background checks count against your plan, Muse pauses when your weekly tokens run out, and Grok Bot's continuous running could be affected by limits.

Head to head: autonomy and control

Grok Bot is the most autonomous on paper, with bots that coordinate and can identify work before being asked, according to SpaceXAI. Duet is the most explicit about guardrails: its approval requirement is documented for messages, payments, signatures and deletions. Muse reportedly uses per-action approval, but the details are thinner. If your priority is never being surprised by a charge, choose Duet. If your priority is hands-off throughput, Grok Bot is the one to test, ideally with low-risk tasks first.

Winner by use case

• Invoicing and supply purchases: Claude Duet, thanks to Stripe's Link wallet and MCP server, with approval on every purchase.
• Marketing on Instagram, Facebook and Meta ads: Meta Muse, for its direct links to those accounts.
• A multi-role team on repeat sales and ops tasks: Grok Bot, if the budget allows.
• Lowest cost to try: Meta Muse.
• Tightest control over spending: Claude Duet.
• Working with apps that have no API: Grok Bot, which operates websites through their interfaces.

What to check before you connect any of them

Whichever agent you pick, it will touch your money and your customer data. Before connecting anything, set up a separate business bank account or card for agent purchases so you can see exactly what it spends. Review your business insurance to see whether mistakes made by an automated agent are covered, and keep your profit and loss statement current so you can tell whether the time saved is worth the subscription. If an agent will email customers or sign documents for you, make sure the right legal entity, such as your LLC, is the one named on those accounts.

Bottom line

There is no single best agent. Pick Claude Duet if you already pay for Claude and want an assistant that never spends without a yes. Pick Meta Muse if you want a free start and your customers find you through Meta's apps. Pick Grok Bot only if you have the budget and the volume to justify a team of bots at $120 per seat per month. All three are new, and two of them are still in preview or beta, so start with small tasks, review what they do, and expand only when the results hold up.
