Classgrid vs OpenAI Dots, Grok Bot & Meta Muse

Introduction

More AI assistants now promise to work for you in the background, and some can talk by voice or make phone calls. But they do very different things. This page compares one thing in detail: giving work to an AI by calling it on WhatsApp, and getting the finished result back on WhatsApp.

We compare Classgrid AI with three new agents: OpenAI Dots, Grok Bot from xAI, and Meta Muse. Everything here is based on public information as of October 2026. These products change quickly, so check their own pages too.

How a WhatsApp call to Classgrid AI works

Classgrid AI is an AI agent at chat.classgrid.in. Sign up, send "Hi" to +91 81492 77038 on WhatsApp, then verify your WhatsApp number with a one-time code. After that, you can call the same number on WhatsApp and just say what you need.

• The AI picks up and greets you by name. You talk normally and can interrupt it at any time.
• It can answer you live during the call, using the apps you connected, like Gmail, Google Calendar, Google Drive, Notion or GitHub. If something takes longer, the answer comes on WhatsApp.
• For bigger jobs, it notes what you asked and starts working as soon as you hang up. Coding and website jobs run in Project Mode, and you can name your project on the call.
• If it needs something from you, it can ask you a question on WhatsApp and wait for your reply.
• When the work is done, you get the result on WhatsApp with a link to the full chat. PDFs arrive as real files.
• You can add more while the job is still running: send a WhatsApp message, or email agent@classgrid.in from your Classgrid account email. A job can keep going for up to 48 hours.

Each call can last up to 15 minutes and the AI speaks English. It is a WhatsApp voice call, so a normal phone call to the number will not reach the AI.

OpenAI Dots

OpenAI launched Dots at its DevDay event on 29 September 2026. Dots are always-on agents that work in the background, each with its own cloud computer, and they connect to more than 4,000 apps (OpenAI, TechCrunch).

You use your dot inside ChatGPT (phone app, desktop app and browser), Slack and Microsoft Teams. OpenAI says texting is coming soon. WhatsApp is not on its list (OpenAI help).

You can voice-call your dot inside ChatGPT by pressing the phone button in its chat. This is a call inside the app, not a phone number, and it is not on WhatsApp. OpenAI says calls started by your dot are planned for later (OpenAI help).

Dots comes with OpenAI's Pro, Business Premium and Enterprise plans (Enterprise is in beta). Pro is open everywhere except the EEA, Switzerland and the UK, so people in India can get it, with a gradual rollout (OpenAI help, Getting started with your dot).

OpenAI's separate 1-800-ChatGPT phone line works in the US and Canada only. ChatGPT on WhatsApp came back in July 2026 in the EEA only, for messages, images and voice notes, with no calls (OpenAI help, The Decoder).

When Dots is a good fit

Dots suits people who already work all day in ChatGPT, Slack or Teams, want agents running in the background there, and are happy to talk to them inside the ChatGPT app.

Grok Bot (xAI)

Grok Bot is xAI's agent, launched in beta on 11 August 2026. Each Bot has its own cloud computer with a browser, files and a terminal, and can work around the clock (xAI).

You use it from apps for macOS, Windows, Linux, iOS and Android, through X Chat, by tagging @bot on X (not in every region yet), or as a shared Bot in Slack (xAI docs, xAI FAQ).

It connects to apps like Gmail, Google Calendar, Google Drive, Notion, Slack and HubSpot, and it can run routines on a schedule (xAI connectors, xAI routines).

Since late October 2026, Grok Bot can call a person or a business for you, make a request, take notes and send you a summary. Elon Musk announced this on X (Musk on X, Tesla North). So Grok Bot calls other people for you. Its apps have a voice mode for talking to your Bot, added in September 2026 (Basenor), but we found no phone number for calling Grok Bot yourself and no official Grok WhatsApp number.

Grok Bot comes with the X Subscription plans Premium, Super and Ultra, plus some older plans (xAI FAQ). xAI has not published a country list for Grok Bot, so we could not confirm it for India (xAI docs).

When Grok Bot is a good fit

Grok Bot suits people who want an agent to phone businesses for them, and who are happy to give it tasks from its apps, X or Slack.

Meta Muse

Meta launched Muse, its personal agent, on 8 September 2026 in the US. It can send emails, book travel and keep working on longer goals, and press reports say it can fill in forms (Meta, PBS).

You use Muse in its own app, on the web at muse.ai, and inside WhatsApp, where you message it like a contact (Meta). We found no way to call Muse on WhatsApp or by phone. A voice chat inside the Muse app has been rolling out since mid-October 2026 (builtwithmuse.com).

Muse is available in the US, Canada and Singapore. It is not in India, and Meta has not announced an India date (iPhone in Canada, Meta, BusinessToday).

In September 2026, Muse started placing calls to US businesses (TechCrunch). Reuters then reported that some of these calls were secretly made by human contractors, and Meta said it rolled back those contractor-made calls (Reuters via KSL, TechSpot).

Separately, Meta AI in WhatsApp has a voice mode: you press a button and talk inside the chat. It is a voice chat in the app, not a phone call to an agent (WhatsApp Blog).

When Muse is a good fit

Muse suits people in the US, Canada or Singapore who want an agent they can message in WhatsApp, on the web or in the Muse app.

Side-by-side

When to choose Classgrid AI

Choose Classgrid AI when you want to hand off work with a WhatsApp call, with no new app to install and no typing, and get the finished work back on WhatsApp. It works in India.

• You are driving, travelling or away from your laptop and want to say what you need in a quick call.
• You want the agent to keep working after the call and send you the result, not just answer a question.
• You want PDFs delivered straight to WhatsApp as real files.
• You want the same agent on the web too, with research, files, code, Project Mode and Grids.

Good to know

• Calls are WhatsApp voice calls in English, up to 15 minutes each.
• First sign up at chat.classgrid.in, send "Hi" to the number on WhatsApp, then verify your number with a one-time code.
• A WhatsApp text on its own does not start a new job. You start a job by calling, or by emailing agent@classgrid.in from your Classgrid account email. A text sent while a job is running adds to that job.
• Classgrid AI is free to start, and you top up only when you need more. Calls and jobs use your AI credits. If credits run out during a job, the job pauses and carries on by itself once you top up.
• Details about the other agents are as of October 2026 and may change. Check their own pages for the latest.
