Price
Muse starts at $0, with a usage limit Meta hasn't published. Power is $20/mo and Max $100/mo.
Grok Bot doesn't have a plan of its own. It comes with SuperGrok ($30/mo), SuperGrok Plus ($100/mo) and SuperGrok Heavy (price not listed on SpaceXAI's pricing page), or with Cursor: Cursor Pro ($20/mo) and Cursor Teams ($40 per user/mo). Its usage is counted separately and resets weekly.
Dots come with ChatGPT Pro ($100, $200 or $500 a month) or Business Premium. Your first dot is included. All three Pro tiers are open to new subscribers; only Pro $500 includes Astra Ultrafast.
Bottom line: Muse for free, Grok Bot for the cheapest paid plan, Dots if you're already on ChatGPT Pro.
What each can do
Meta says Muse browses the web, fills in forms, sends email, books travel, makes purchases and negotiates for you.
A dot has its own cloud computer and browser, works through connected apps (OpenAI says 4,000+ through plugins), runs scheduled tasks and does background research with read-only tools.
Each Grok Bot gets a persistent cloud computer with a browser, a filesystem and a terminal. SpaceXAI says bots work across apps and websites, learn workflows from demonstration and coordinate with each other.
Bottom line: Muse is pitched at errands, Dots at ongoing work in your apps, and Grok Bot at multi-step jobs on a computer of its own.
Where you use it
- Muse: iOS, Android and the web; glasses "coming soon."
- Dots: set up on ChatGPT's web or desktop app; chat from the mobile app, Slack or Microsoft Teams; SMS in a limited US beta.
- Grok Bot: macOS, Windows, Linux, iPhone, iPad and Android.
Safety and privacy
Muse runs in a dedicated cloud machine, and a separate "Sentinel" agent must approve anything that reaches the internet. Its Confidential VM, with a key you hold, is announced for later in 2026 but not live.
Dots get automatic review of actions that affect your accounts, and you write Custom Rules for what a dot may do alone. Resetting a dot deletes its conversations, memories and scheduled tasks.
Grok Bot asks for approval before it sends messages, publishes, buys, transfers money, deletes data, changes permissions or accepts legal terms. You can add Auto Review rules; when an "ask first" rule and an "allow" rule both match, ask first wins. Deleting a bot doesn't remove files or sessions already on its cloud computer.
Bottom line: Grok Bot publishes the most specific approval list. Dots gives you the most rules to write. Muse's strongest privacy feature isn't shipped yet.
