Short verdict: Meta Muse is the pick for personal productivity and marketing on Meta's platforms, Viktor is the pick for a shared teammate in your team's chat, and Grok Bot is the pick for work inside tools that have no connector. OpenAI Dots may turn out to be the broadest of the four, but it launched on September 29, 2026 and has no field record yet.
These four get compared as if they were after one job. They're built for different jobs, and none of them is the company-owned department with approved sources and review points, which is the job we do. The product facts below come from the companies' own pages, launch coverage and independent reviews, as of September 2026.
Meta Muse: the fast personal agent
What it is. A personal AI agent from Meta. In our own use it was fast.
Where it runs. In Meta's Muse apps, with its integration code running on a virtual machine in Meta's cloud. Facebook, Instagram and Threads connect automatically when the accounts share an Accounts Center. It also connects to Gmail and Google Workspace.
What it costs. A plan that costs nothing, with usage limits, plus paid tiers. We haven't seen per-task pricing published.
Best at. An independent ten-task business review on September 27, 2026 scored meeting prep and background tasks highest, found briefs and content plans improved with Meta account context, and gave it 6.5 of 10 as an overall impression. By default Muse won't take many important actions, like sending an email, without approval.
Where it stops. That review advised against using it where a job needs credentials or broad file access. Meta's help page says Meta doesn't review custom connectors. When we read that page, it had no troubleshooting steps for failed connections and no mention of WhatsApp. In our own test, two custom connections to business systems failed at sign-in, which we wrote up in we tried Meta Muse for a services business.
OpenAI Dots: days old, broad on paper
What it is. Always-on personal AI agents in ChatGPT, powered by GPT-6 Astra. Each learns from feedback and is built to keep working toward goals around the clock.
Where it runs. Each dot runs on its own cloud computer with its own browser, and you can open that computer to inspect its work. You reach it in ChatGPT on desktop, web and mobile, by message or call, and in Slack and Microsoft Teams. It connects through OpenAI's plugin ecosystem to more than 4,000 apps.
What it costs. One agent is included with a Pro or Business Premium plan at no extra cost. For the first month, usage doesn't count toward plan allowances. Usage terms after that hadn't been published when we checked.
Best at. On paper, breadth. An inspectable computer is a thoughtful design choice.
Where it stops. Nobody knows yet. Dots launched on September 29, 2026, and it's too new for independent field reviews. Rollout began with Pro, outside the EEA, Switzerland and the UK, and with Business Premium. Enterprise is off by default until an admin enables it.
Viktor: the shared teammate in chat
What it is. An AI employee the whole team shares. Viktor's own line is that the team gets an analyst, an ops lead and an engineer.
Where it runs. In the Slack, Microsoft Teams or Discord channels you invite it to, with more than 3,200 integrations, Salesforce, HubSpot and Stripe among them.
What it costs. Pricing is by workspace with no per-seat charge. You can start with $100 in credits and no card, and paid plans begin at $50 a month for 20,000 credits. Viktor says it adds no markup on model costs.
Best at. Executing instead of advising. It returns the finished thing: a report, a dashboard, a campaign, a CRM update. It handles recurring work on a schedule and proposes automations. Viktor says it asks for confirmation before high-stakes actions like sending emails. Its site states SOC 2 Type 1.
Where it stops. It works on request or on a schedule. An independent review from August 2026 found that nothing starts because a customer replied and that it doesn't treat an inbox as a channel to act on. The same review put a working month at $150 to $400, well above the entry tier. The full picture is in Advisy Nexus vs. Viktor.
Grok Bot: work inside tools with no connector
What it is. A persistent, named agent from xAI, in public beta since August 11, 2026. It's built to run a job on its own and come back when something needs your approval.
Where it runs. On its own always-on cloud computer with a browser, files and a command line. It signs into the tools you already use, so it can work inside tools that have no API or connector. There are desktop apps for Mac, Windows and Linux and an iOS app, and an Android app arrived in early September 2026. The launch coverage we read mentioned no Slack integration.
What it costs. There's no standalone price. It's included with SuperGrok plans and with Cursor plans, which coverage lists from Cursor Pro at $20 a month up to Ultra at $200, and Cursor Teams Premium at $120 per seat.
Best at. The job connectors don't reach: the old portal or back-office tool with no API.
Where it stops. It's a beta. Launch coverage noted that xAI hadn't detailed how the sign-in to your tools works, and later write-ups point out that all the Bots on one account share a single cloud computer, so they aren't walled off from each other's logins.

Which job is which
Personal productivity
One person who wants meeting prep, research and a weekly brief. Muse is fast and has a published test behind it. Dots is aimed at the same job and may prove broader once it has a record.
A shared teammate in chat
A team that lives in Slack or Microsoft Teams and wants finished work back. Viktor was built for exactly that. Dots reaches both as well, but it's days old.
Work inside tools with no connector
Picture a recruiting firm with a job board portal that has no API. Grok Bot is designed for that. Remember it signs into your tools, and it's a beta.
The company-owned department
Work that touches customers and money needs approved sources, review points and a named person at the decision point. We build that with Nexus: a person installs it after the two-day audit, the artifacts stay in your folders, and your team is trained. We don't claim it has more integrations or a lower price than any of the four.
You don't have to choose only one. Advisy will set up Muse, Dots, Viktor or Grok Bot for a client when the audit points there. For more options, see Advisy Nexus vs. Marblism and the best AI employee alternatives for small services businesses.
Frequently asked questions
Which is best for a small services business?
It depends on the job. As of September 2026, Muse suits marketing and research on Meta's platforms, Viktor suits a team in chat, and Grok Bot suits tools with no connector. Work that touches customers and money needs review points around whichever you choose.
Is OpenAI Dots ready for business use?
Nobody can say yet. Dots launched on September 29, 2026 and has no independent field reviews. We'd try it on low-risk work and wait for a record before relying on it.
Which of the four works in Slack?
Viktor and Dots. Viktor also works in Microsoft Teams and Discord, and Dots in Microsoft Teams. The launch coverage of Grok Bot that we read mentioned no Slack integration, and Muse runs in Meta's own apps.
What does Grok Bot cost?
It has no standalone price as of September 2026. It comes with SuperGrok plans and with Cursor plans.
Does Advisy only recommend Nexus?
No. The two-day audit looks at how work moves through your business. If one of these four fits the problem, we say so and set it up. Nexus is for the workflows you want to own.
Name the reviewer, then pick the tool
Four products, four jobs. What doesn't change is that somebody has to decide the work is right before it leaves. Name that person first. The tool is the second decision.
Which job is which inside your company is what the two-day audit sorts out. Tell us how your business runs today, and we'll come back with one recommended first project and the person who will own it.
