Grok Bot vs Muse: What the Community Says (/Last30Days)

Quick Verdict

Two billionaires shipped the same idea a month apart, and the community already picked a favorite by download count. @naeem_sanzox put it bluntly: "Zuckerberg's AI agent got about 4x the downloads of Musk's. Muse hit #1 on the App Store in 10 days. Grok Bot told users to photograph their credit card." The numbers back that up: Sensor Tower's "Muse Races to 10mn US Downloads" report puts Muse at 10.9 million US downloads in 40 days, making it only the 12th app ever to hit that mark that fast, with 30 straight days atop the US Google Play Store and 12 consecutive days leading the App Store, per TechCrunch. Grok Bot, by contrast, shows 1M+ downloads on its Google Play listing with a 4.2-to-4.6 star spread across 9.3K to 14.9K reviews depending on the snapshot. These aren't really the same product - Grok Bot is a roster of persistent AI coworkers with their own cloud computers (10,000+ App Store ratings at a 4.9 average per @cb_doge), while Meta's Muse crossed 10M users with shopping as the top activity per @pricepertoken, a figure CNET sharpens to a quarter of all 10 million users shopping via Muse at an average spend of $200 each. Grok Bot is the power-user's agent fleet; Muse is the normie's pocket assistant. As Meta's own @alexandr_wang trolled: "muse gang, say hi to the boomers on grok bot." It's worth noting Meta Muse and plain old "Muse" get used interchangeably across the threads, and @meta itself leans into that blurring when it posts about the product.

Grok Bot

Grok Bot gives you a roster of AI teammates with their own cloud computers, and the X crowd treats it like hiring staff. @Texas_Twins_Dad laid out the pitch in a 1,648-like post: dedicated email, voice, "its own computer," connectors for Gmail/Calendar/Notion/Drive/X, and scheduled routines that "work while you sleep." @atlasberry008 showed a proactive version of this too, Bots that read across calendar, Gmail, Notion, Slack, and Drive and flag what needs attention before you ask (31,849 views). The structure power users converge on is a chief-of-staff bot with specialized bots under it, as Moritz | AI Systems explains ("one bot per job... treat a bot like having a new employee"). The Google Play listing itself undersells the complexity power users describe, pitching "easy setup, just explain what you want automated" per the October 2 update.

Strengths: practitioners cite serious workflow consolidation. @emigal says it "replaced 100% of my Hermes usage & automations" and now "runs 100% of my Cursor cloud agents, reviews PRs, merges for me" (871 likes). @andrewcodesmith calls his Grok Bots a "software team who never sleep," working seamlessly with Cursor from the cloud even with the laptop shut (4,569 views). @artzenmedia built three teammates, Axel, Bill, and Bob, to handle recurring payments, invoices, and receipts, and found $283 in subscriptions nobody was using. Founders School, a former multi-million-dollar agency owner, says "I don't even need to go into Codex or Claude anymore." @itsolelehmann called it "the agent product Steve Jobs would've cooked" (599 likes). On r/GrokBot, u/jadmorffier used it to audit 200 weekly payslips and found 72 weeks of underpayment (32 upvotes).

Weaknesses: the security story is ugly, and it's now tangled up with a deliberate product push. On October 10, Musk told users to upload photos of their credit cards so Grok could shop on their behalf, a move covered by NDTV alongside user security concerns. Two days later, SpaceXAI quietly updated both the Grok consumer terms and the separate Grok Bot terms, with the new language reading "We cannot control what you provide us. You are responsible for all actions," per Cybernews. Ethical Growth Partners' breakdown of the fine print puts it plainly: "You are responsible for what the agent does. You set its permissions." The Hacker News thread on Grok Bot spilling a tech CEO's bank data in a public Slack hit 36 points. @TrentonDAdams says "Grok Bot has so many problems... For one task can just vanish" and @enesakar calls voice chat "really bad, not usable." On r/grok, one user raged that Grok ate ~50% of usage "for like 10 pics" (78 upvotes). The Polymarket market on Grok Bot reaching the free plan sits at just 10%, down 3.8% this week.

Muse

Meta's Muse hit 10M users and #1 on the App Store in 10 days, with shopping as the top activity. That trajectory has only accelerated: Sensor Tower confirms Muse became the 12th app in history to clear 10 million US downloads within 40 days, and 9to5Mac notes it's also outpacing peers on retention, not just install velocity. Digital Today frames it as Meta's fastest app growth since Threads. The launch of Muse Wonder, Meta's "strongest frontier class model yet" with active memory that "retains all your work that matters," pulled 1.5M views and 17,165 likes on @muse's own reel. @finkd confirmed Wonder is also available through Muse Code and the Meta Model API. Meta's broader naming churn around the product shows up in the wild too, some threads reference a lighter "Muse Charm" tier alongside Wonder when discussing which model handles which task, even as the flagship branding stays simply Muse.

Strengths: normies love the zero-friction life admin, and shopping is turning out to be the killer use case by a wide margin. CNET reports that roughly a quarter of Muse's 10 million-plus users are shopping through the agent, spending an average of $200 per session. On r/MuseAgent, u/Pure-Most6715 said "I'm so integrated w muse that I don't even feel like trying dots or grokbot - muse is insanely helpful" (52 upvotes), though u/rickestrickster pushed back in the same thread that Dots caught more bills in a bank-statement test than Muse did. @austinnotduncan had Muse build a 300-receipt database he'd put off for six years, in 30 minutes (548,305 views). @engineeringwithpalden used a Muse bot named Scout to find professors and draft research-assistant emails in under five minutes (1.86M views). @paytonkaleiwahea notes Muse edits video from your phone, no computer to remote into, unlike Claude Code and Codex. Over on r/MetaAI, a thread titled "How is muse that good?" compared it favorably to Astra and Gemini for following instructions without hallucinating.

Weaknesses: the trust problem is existential. The Ars Technica report that Muse exposes users' personal and business secrets when they share conversations hit 408 points on Hacker News. @yersocialistdad relayed a Mac security expert's three-word verdict, "Please don't install," to 359,703 views, and the top comment (4,440 likes) was "I refuse to install anything Meta." On r/MuseAgent, a "Is Muse getting dumber?" thread complained of forgotten tasks and gaslighting (20 upvotes), and r/artificial flagged that Meta's commercial terms make AI mistakes "legally be the customer's fault" (314 upvotes), a liability-shifting move that echoes Grok Bot's own October 12 terms update almost exactly.

Head-to-Head

The Bottom Line

Choose Grok Bot if you're a developer or operator who wants a fleet of persistent agents handling PRs, Cursor handoffs, and business ops while you sleep. @ArjitJaiswal7 put it plainly: "Grok Bot is actually the way I want to work with agents. Codex has nothing close" - just budget for the usage burn and keep sensitive credentials, and definitely credit card photos, away from it after the Slack leak and the October 12 terms update that puts liability squarely on you.

Choose Muse if you want a free, zero-setup pocket assistant for shopping, bookings, receipts, and calendar admin and you can stomach handing Meta the keys. @austinnotduncan proved the appeal (six-year task done in 30 minutes), and CNET's $200-average-spend shopping data shows millions already trust it with real purchases, but take the "Please don't install" security warnings seriously before you connect your accounts.

The emerging stack

The pattern power users keep posting is multi-agent, not single-vendor: on r/MuseAgent people run Muse alongside Dots and compare bill-analysis accuracy, and on Threads @darcie91410 stitches "Opus 5.5 + REA + Jev + Dots + Grok Bot + Obsidian" into one income workflow. @droidbuilds is part of that same crossover chatter, posting build logs that treat Grok Bot and Muse as interchangeable backends for the same automation scaffolding rather than rival ecosystems. The clearest crossover is Grok Bot riding other companies' subs - @nateherkai and @colton.deannn both show Grok Bot running on your Claude Code / Claude subscription, and @mr.paidsocial wires Grok Bot, Claude Code, Codex, and a Mac Mini together over Tailscale. The community verdict isn't "pick one," it's Grok Bot as the dev-side orchestrator and Muse as the consumer-side assistant, with the Scale-vs-xAI founder sniping (@Coherent_Design: "Even Muse Wonder (not Full) has a higher AA score than Grok, bro") as background noise. (Separately, several Pinterest and Digg clusters keep surfacing tennis player Lorenzo Musetti whenever "Muse" gets clipped in search, a reminder that the name collision is pure noise, not signal, for this comparison.)
