Our verdict: Gemini Spark is the best personal AI agent for most people. Meta Muse is the best free one, OpenAI Dots is the most powerful, and Grok Bot is the best value if you want several agents at once.
A year ago, an AI assistant that worked while you slept was a demo. Now there are seven worth knowing. Each one gets its own cloud computer, keeps working after you close the app, and asks before it spends money or sends a message.

How big AI assistants got in 2026
The agents are young but catching on fast. About a quarter of people who set up Muse use it every day, Meta says, and launches haven't slowed: ChatGPT Work in July, Siri AI in September and Grok Bot's move into The X Subscription on October 12.
The 7 agents at a glance
Gemini Spark- Runs in Gmail, Calendar, Drive and Docs
- 40+ connected apps, Chrome auto browse
- 150+ countries
The catch: built around Google apps.
Meta Muse- Errands by message in its app or WhatsApp
- Shops with one-time Link card numbers
- A second agent approves what it sends
The catch: Meta can still reach your data for now.
OpenAI Dots- GPT-6 Astra on its own cloud computer
- 4,000+ apps through plugins
- Custom rules: allow, ask or block
The catch: Pro only, and not in the EU or UK.
Grok Bot- Several bots running in parallel, 24/7
- Learns a workflow you show it once
- Checkout with Shop Pay and X Money
The catch: all your bots share one computer.
Claude Duet- Morning brief, checks your apps every few hours
- 6,000+ connectors
- Strictest safety rules here
The catch: US waitlist, weaker at errands.
ChatGPT Work- Works across your apps and files
- Delivers docs, slides and web apps
- Scheduled tasks while you're away
The catch: only works when you ask.
- Orders takeout, books rides and repairs
- On Echo devices, the app and Alexa.com
- Mostly US, India next
The catch: no long background projects.

Gemini Spark: best for most people
Spark works in Google's cloud on top of the apps most people already use. It triages your inbox, drafts replies from your own documents and runs scheduled tasks. Since October 13 it also connects to more than 40 apps, including Instacart and OpenTable.
It's included in Google AI Pro at $19.99 a month, the price of a plain chatbot plan, and it reaches the most countries.
Meta Muse: best free agent
You message Muse in its app or WhatsApp, and it handles email, bookings, forms and bills. A separate Sentinel agent must approve anything Muse sends to the internet.
Shopping is its strength. Muse pays with Link by Stripe, which creates a one-time card number, so neither the store nor the agent sees your real card.
OpenAI Dots: the most powerful
Each dot runs on GPT-6 Astra with its own cloud computer and browser, and connects to more than 4,000 apps. Its controls are the most detailed: Custom Rules let you allow, require approval for or block specific actions.
The first dot comes only with ChatGPT Pro, from $100 a month, and the Pro rollout skips the EU, UK and Switzerland.
Grok Bot: a team of agents for $30
Grok Bot, sometimes called "Grokbot," thinks in teams. You create bots for separate jobs, like sales follow-ups or expenses, and they run in parallel around the clock and check in when they need approval. Show one a workflow once and it saves it as a routine.
Since October 12 it's part of The X Subscription, with Premium at $30 a month. All your bots share one cloud computer, with the same files and logins.
Claude Duet: the careful newcomer
Anthropic's always-on agent opened as a US waitlist on October 21. It sends a morning brief, checks your apps every few hours and shows you exactly what it's about to do before it sends, pays, signs or deletes anything. Moving money between accounts is off-limits even with approval.
ChatGPT Work and Alexa+
ChatGPT Work is OpenAI's on-demand agent. It stays with a project for hours to deliver finished docs, slides or web apps, free in limited form on desktop or fuller with Plus at $20 a month. It works when you ask rather than watching your inbox.
Alexa+ orders takeout, books rides and schedules home repairs. It's free with Prime, or $19.99 a month without it, and mostly US-only for now.
What about Siri, Copilot, Perplexity and Manus?
Siri AI (iOS 27) acts inside apps but only when you ask. Microsoft Copilot's Autopilot agents are still in a limited test. Perplexity's Computer agent, with Pro at $17 a month billed yearly, is built for research rather than errands. Manus now belongs to Meta.
Which agent should you use?
The verdict
Gemini Spark is the best personal AI agent for most people in 2026. It's always on, works inside apps billions already use, and costs $19.99 a month. Start with Meta Muse if you want free, pick OpenAI Dots if you already pay for ChatGPT Pro, and choose Grok Bot to run a team of agents for $30 a month.
