The AI Tools Blog · Updated November 2026

Muse, Grok and Symphony — explained in plain English.

Everyone is talking about AI agents. Here is what the three biggest new tools actually do, what they cost to start, and how to pick the right one for your business.

01 — by Meta

Muse

A personal AI agent that does the work, not just answers questions.

Meta launched Muse in the United States on September 8, 2026. It is a personal AI agent — meaning you tell it what needs to get done, and it takes action for you.

You talk to it just like texting a person, either in the Muse app or right inside WhatsApp. It runs on its own secure computer in the cloud with its own browser, so it can work across the apps you already use.

What it can do

  • Sends emails and helps manage your calendar
  • Books travel, reservations and online purchases
  • Connects to apps you approve — email, calendar, payments and more
  • Turns long-term goals into step-by-step action plans
  • Learns from your conversations and gets sharper over time

How to get started

  • Download the Muse app, or message Muse in WhatsApp
  • You must be 18 or older
  • You decide how much access it gets to each app

Best for: The business owner who wants one personal assistant for email, scheduling and everyday to-dos.

Watch out: Muse can act in your accounts. Reuters reported early internal tests found stalling and data-exposure problems, so give it limited access at first and approve anything important.

Grok

An all-in-one AI assistant for writing, research, images and video.

Grok is the AI assistant from xAI, available at grok.com and in the iPhone and Android apps. It searches the web and X live, so its answers reflect what is happening right now.

Its newer Grok Bot feature gives you named AI teammates that work on their own cloud computer, remember context, and come back to you when something needs your approval.

What it can do

  • Writes, researches and recaps with step-by-step reasoning
  • Creates images and short videos (up to 15 seconds) from a prompt
  • Reads your PDFs, spreadsheets and photos
  • Connects to your email, files and calendar
  • Grok Bot can learn a task once and repeat it on a schedule

How to get started

  • Free to start at grok.com or in the app
  • Paid SuperGrok plans raise your limits
  • Grok Bot is included with certain paid plans

Best for: The business owner who creates a lot of content and wants research, captions, images and video in one place.

Watch out: Image and video tools are powerful — always check that anything it creates fits your brand before you post it.

Symphony

A whole team of AI agents built to run the daily tasks of a small business.

Wix launched Symphony on August 11, 2026. Instead of one assistant, it builds you a team of AI agents. You only talk to one of them — Maestro — and it hands the work to the right agent.

You do not need a Wix website to use it. It works in your browser and in the iPhone and Android apps. Each day the agents give you a short morning summary of what they did and what needs you.

What it can do

  • Appointment confirmations and reminders
  • Following up on overdue invoices
  • Outreach drafts and lead follow-ups
  • Marketing, research, finance and design help
  • Connects to your calendar, inbox, payments and other tools

How to get started

  • Free plan with 500 AI credits a month (up to 100 a day)
  • Works with or without a Wix website
  • Flags important actions for your approval

Best for: The service business owner who wants bookings, reminders, invoices and follow-ups to run on their own.

Watch out: Free credits can run out fast on bigger jobs, so start with one or two tasks and watch your usage.
