2026 年最佳 AI 代理：真正替你做事的助理

精選推薦

1. 

   Grok Bot

   SpaceXSI (formerly xAI)

   US$30/月

   Always-on AI agents from SpaceXSI that run on a shared cloud computer, sign in to your apps and finish multi-step work while you're away.

   優點

   • Bots work on their own cloud computer, so tasks keep running when your laptop or phone is closed
   • Can operate websites and apps that have no API, using saved logins it never sees in plain text
   • Several Bots can run in parallel, message each other and share one workspace
   • Routines can run on a schedule or after an event, and a Bot can learn a task from a recorded demonstration of up to 10 minutes
   • Can place phone calls to US businesses for you and send a summary afterwards
   • Native apps for macOS, Windows, Linux, iOS and Android, plus Slack

   缺點

   • No free plan and no standalone price: the cheapest way in is the $30/month Premium plan
   • Usage comes from a weekly pool shared with Grok and Cursor, and SpaceXSI does not publish how much work that pool covers
   • No model picker: Grok Bot chooses the model for each task and does not show which one it used
   • All Bots on an account share one computer, files and logins; the docs say not to use separate Bots as a security boundary
   • Users report Amazon blocks it from shopping as an unauthorized AI agent; Amazon hasn't commented
   • Still labelled beta, with no browser version

   Manus

   Manus

   US$20/月

   General-purpose AI agent that researches, builds websites, slides, videos and games, and runs automations on its own cloud computer.

   優點

   • Turns one prompt into finished output: research reports, websites, slides, videos and playable games
   • Automations can start from a schedule or an event in a connected service such as Gmail, Slack or Notion
   • Video Editor and Game Dev let you edit what the agent made instead of regenerating it
   • Free plan to try it, with apps for web, iOS, Android, macOS and Windows

   缺點

   • Credit-based pricing makes costs hard to predict, and long or failed runs can use up credits
   • Free daily credits are capped at 1,500 a month and only work in the Lite mode
   • A built-in training opt-out is listed only for Team plans
   • Several plans share the Pro name and differ only by credit amount

   Rakazo

   Rakazo

   US$10/月

   Open-source, self-hostable platform for persistent AI bots that each get a job, a computer, memory and routines, using the model you choose.

   優點

   • Open source (Apache-2.0) and fully self-hostable, including with local models
   • Choice of model per bot, including existing Claude or ChatGPT subscriptions
   • Bots keep working on schedules and triggers with their own cloud computer
   • Approval controls over which actions a bot may take on its own

   缺點

   dots

   OpenAI

   US$100/月

   OpenAI's always-on agent inside ChatGPT, with its own cloud computer, that works on your goals between chats and reaches you in ChatGPT, Slack or Teams.

   優點

   • Runs on its own cloud computer and browser and keeps working when your devices are off
   • Connects to over 4,000 apps through ChatGPT plugins and can hand work to Codex and ChatGPT Work
   • Reachable in ChatGPT, Slack and Microsoft Teams, and you can call it, with one memory across channels
   • Researches your connected apps on its own and brings you finished work or decisions to review
   • Custom Rules and Auto-review gate sensitive actions, and some steps always stay with you

   缺點

   • No free, Go or Plus access: it needs ChatGPT Pro from $100 a month or Business Premium
   • Pro access excludes the EEA, the UK and Switzerland
   • One dot per user for now; teams of dots are only planned
   • Texting over iMessage or RCS is a US-only beta, and your dot cannot call you yet
   • Stopping a task does not undo actions it already took, and tasks it starts in Codex or ChatGPT Work count toward those limits

   Perplexity Teammates

   Perplexity

   US$200/月

   Persistent Perplexity agents, each with its own computer, browser and memory, that own ongoing work and watch Slack, GitHub and Linear. Max-only web preview.

   優點

   • Run several teammates, each on its own isolated computer and browser with separate sessions
   • Watches Slack, GitHub, Linear and other connected tools, acts on changes and reaches out when it needs you

   • You can take over a teammate's desktop and steer it, and it can't view your saved credentials

   缺點

   • Only on Perplexity Max at $200 a month; Pro and Enterprise plans are excluded by default
   • Research preview whose behavior may change
   • Web only for now; the iOS app is only promised soon
   • Usage draws on credits, and parallel agents, large files and frequent automations use more
   • No published cap on teammates and no published credit cost per task

   Muse

   Meta

   US$20/月

   Meta's personal AI agent that sends email, books travel and shops for you from its own cloud computer, in the Muse app or on the web.

   優點

   • Free tier, and no technical setup: you message it like a person in the app or on the web
   • Runs on its own cloud computer and keeps working after you close the app
   • Asks before sending email or buying, and shows an audit trail of what it did and plans to do
   • Purchases go through a one-time card number with Link's purchase protections, so the agent never sees your real card
   • Connects to email, calendar and Instagram, and can use a browser for sites without an API

   缺點

   • Only in the US, Canada, Japan, Singapore and Mexico so far, and Meta says Muse is still in limited testing
   • Requires a payment card even for the free tier, and the stronger Muse Wonder model is for paid plans only
   • Your interactions train Meta's AI models unless you opt out
   • Free usage limit is not published, so it is hard to know when you will hit it
   • Early users and press reported it overstepping permissions, such as reading messages it was not meant to
   • Requires a Meta account and asks for broad access to email, calendars and payments

   OpenClaw

   OpenClaw Foundation

   –

   Free, MIT-licensed personal AI agent that runs on your own computer and takes orders from WhatsApp, Telegram, iMessage, Slack and 20+ other chat apps.

   優點

   • Free and MIT licensed, with no paid tier
   • Runs on your own hardware; state, memory and credentials stay local, and it sends nothing home except an optional daily version check
   • Works in 29 chat channels, including WhatsApp, Telegram, iMessage, Slack, Discord and Microsoft Teams
   • Model-agnostic: 64 model and media providers, plus local models
   • Large ecosystem of skills and 142 official plugins, and very active development

   缺點

   • Model costs are on you and can run high: testers and users have reported spending over $100 in a day with expensive models
   • Sandboxing is off by default and the agent can run commands on the host unless you turn on approvals
   • Setup and upkeep expect comfort with the command line; maintainers warn it is risky for non-technical users
   • Broad access to email, messages and the system makes prompt injection and malicious third-party skills a real risk

   Hermes Agent

   Nous Research
