2026 年最佳 AI 助手：真正能替你办事的那些

精选推荐

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.

   优点

   • 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

   缺点

   • 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

   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.

   优点

   • 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

   缺点

   • Still in beta, with frequent releases
   • You supply and pay for the model on the hosted plans, unless you buy Rakazo credits
   • Telegram, WhatsApp and iMessage/SMS are only available when self-hosted
   • More setup than a single chat app

   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.

   优点

   • 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

   缺点

   • 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

   US$20/月

   Free, MIT-licensed AI agent from Nous Research that runs on your own machine or server, learns reusable skills, and chats with you on Telegram, Slack and more.

   优点

   • Free and MIT licensed, and runs on hardware you control
   • Writes and refines its own skills from experience, on top of persistent memory and cross-session search
   • One gateway for 20+ chat platforms, including Telegram, Discord, Slack, WhatsApp, Signal and email
   • Run several separate agents as profiles, each with its own model, memory and skills, and let them talk in group chats
   • Model-agnostic, with a one-command import from OpenClaw

   缺点

   • Setup expects comfort with the command line and with running your own server
   • Model costs are on you unless you use free models, and hosted web search, images and speech need a paid Nous Portal plan or your own keys
   • iMessage needs a separate BlueBubbles server on a Mac
   • No native mobile app; Android support is a command-line install through Termux

   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.

   优点

   • 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

   缺点

   • 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

   Instinct

   Anthropic's proactive agent app: briefs you each morning, works on its own cloud computer and asks before acting. US waitlist preview for paid Claude plans.

   • Works with over 6,000 connectors and plugins, and uses a cloud browser for sites without one
   • Brings your existing Claude memory, skills and connectors from the first message
   • Asks before sending, paying, signing or deleting, and blocks trading and moving money even with approval

   US$49.99/月

   An AI assistant for work that runs your inbox, calendar and meetings, takes requests by iMessage, Slack, phone or browser, and sends you daily briefs.

   • Asks for approval before anything with outside impact
   • Says it never uses your data to train models, with SOC 2 Type II, GDPR and PIPEDA compliance

   缺点

   • Expensive for individuals: paid seats start at $49.99 per user a month, and free credits last only 7 days
   • Credit-based usage is hard to predict, from 2 credits for a simple ask to 2,500 for a big build
   • One shared Lindy per team rather than separate assistants for different jobs
   • No mobile app; on phones you use iMessage, SMS or calls
   • Plan names differ between its pricing page and its docs, so it is hard to tell what each tier includes

    US$20/月

    • 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
