In 6 weeks, 3 of the biggest AI companies launched the same kind of product: an AI assistant that doesn't wait for you to type.

All 3 work the same way underneath. The assistant gets its own computer in the cloud, signs in to your email, calendar and other apps, and keeps working after you close the laptop. It comes back when the job is done or when it needs your OK to send, buy or delete something.

The difference is who they're built for. Grok Bot is a team of assistants for work. Dots are a ChatGPT power-user's assistant that can also ship code. Muse is a personal assistant for your life.

You create several Bots, each with a name and 1 job: Sales Outbound, Inbox Manager, Expense Manager. They share 1 cloud computer, remember what you teach them and hand work to each other in group chats. The standout feature is teach-by-demo: do a task once while a Bot watches, and it saves it as a routine.

In October it got a lot better. It now routes tasks to other companies' models, including Claude Opus 5.5. Bots got their own email address, free access to public posts on X, and deeper Cursor integration for building software. Since October 12 it's part of the X Subscription, 1 plan for Grok, Cursor and X Premium, from $30 a month.

Best for founders, sales and ops teams with recurring busywork spread across many tools, including ones with no API. Downside: you can't pick the model, and all Bots share the same logins.

Setup, use cases, pricing and how it compares to Claude are in our Grok Bot guide.

OpenAI's take, built into ChatGPT and powered by GPT-6 Astra. You get 1 "primary dot" with a name and a cartoon face. It has its own cloud computer and browser, connects to ChatGPT's 4,000+ apps, and you can talk to it in ChatGPT, Slack or Microsoft Teams. With your permission it can also use your own laptop through the ChatGPT desktop app.

The strongest part is code. A dot can hand work to Codex, so it can watch customer feedback, fix the small bugs and send you pull requests with a video of each change.

Best for people already deep in ChatGPT and Codex. Downsides: you need ChatGPT Pro or Business Premium, it's not available in the EU, UK or Switzerland, and you get only 1 dot for now.

Meta's personal agent, on the Muse Spark model. It fills in the school form you forgot, books movie tickets the minute they open, sorts your inbox and shops for you, paying with a one-time card number through Link by Stripe. Talk to it in the Muse app, on the web, on Mac or in WhatsApp. It has a free tier and went to the top of the app stores in its first week.

Best for personal life admin and families. Downsides: US only, Amazon blocks it, and it wants broad access to your email, calendar and payments. Your chats are used for model training by default (you can turn that off).

All 3 ask before sending, buying, publishing or deleting, and none of them will type in your password for you. The details differ:

Anthropic doesn't have a direct equivalent yet. The closest pieces:

A chatbot answers when you ask. An always-on assistant like Grok Bot, dots or Muse has its own computer, signs in to your apps and keeps working on a task after you close the app, coming back only for approvals.

Muse has a free tier. Grok Bot starts at $30 a month with the X Subscription. Dots need ChatGPT Pro or Business Premium.

For work with many recurring jobs, yes: you can run several Bots, teach them by demo and use them anywhere. Dots are better if you already live in ChatGPT and Codex, and have more app connections.

Grok Bot is rolling out globally with the X Subscription. Dots aren't available in the EU, UK or Switzerland for personal Pro accounts. Muse is US only.

They're as safe as the permissions you give them. Keep approvals on for anything that sends, buys or deletes, and only connect the accounts the assistant really needs.
