   Grok Bot

   SpaceXSI (formerly xAI)

   月額$30

   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.

   長所

   • 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

   短所

   • 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

   月額$10

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

   長所

   • 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

   短所

   • 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

   Hermes Agent

   Nous Research

   月額$20

   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.

   長所

   • 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

   短所

   • 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

   dots

   OpenAI

   月額$100

   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.

   長所

   • 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

   短所

   • 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

   月額$200

   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.

   長所

   • 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
   • Pick the model per teammate or task, with Claude Opus 5.5 as the default
   • Splits a goal into parallel agent tasks, and teammates in a Project share context and hand work to each other
   • You can take over a teammate's desktop and steer it, and it can't view your saved credentials

   短所

   • 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

   Claude Duet

   Anthropic

   月額$20

   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.

   長所

   • Messages you first: a morning brief from your email and calendar, then check-ins every few hours
   • 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
   • Pays through one-time card numbers via Link and Shop Pay, and turns larger jobs into editable briefs, decks and dashboards

   短所

   • Waitlist-only research preview, US only, and not on Team or Enterprise plans yet
   • Uses the same Claude usage limits as chat, and background checks count too
   • One model only, Claude Opus 5.5, with no choice of model
   • Anthropic's docs say you can't yet watch or take over its browser
   • Microsoft 365 isn't available yet, and it can misread threads, misjudge urgency or miss things between check-ins
