Editor's Verdict

Viktor works inside Slack or Teams, reads team channels, and proactively offers to handle business tasks. Muse waits in a personal chat for requests like shopping, returns, forms, and monitoring deals.

For business, choose Viktor. It learns team processes, remembers preferences, executes work across connected tools, and adapts to roles from operations to engineering. The whole team adopted it quickly because it asks for what it needs instead of making people explain every workflow upfront. Read our full Viktor review for more wins we've had.

Muse is the better fit for personal tasks. It is easy to use through a familiar chat or WhatsApp, keeps working after you close it, and handles recurring errands without requiring an automation builder. It is currently free.

In our business, we use both. Viktor as a collaborative AI employee in Slack and Muse as a personal AI assistant.

Viktor vs Grok BotAI Agent

Viktor Editor's Verdict

What is Viktor?

Viktor is the business-focused executive assistant of the bunch.

If you've tried the other apps on this page and have felt "this is too personal/consumer-focused", then what you actually need is the AI personal assistant that's built for founders. While it can still do the personal side that AI assistants, it's more geared toward business owners and solopreneurs, looking for an employee to help hand things off to.

Viktor works in Slack and Microsoft Teams, so it has full context on what is happening inside of your business. It is also an agent, so it can also go off and execute tasks for you.

Imagine you have a new project idea, but instead of needing to write an entire brief, Viktor has context from your conversations with your team mate, so you can just tell him to get started on it.

Pros and Cons

Pros

Viktor has the most integrations of everything else listed here, but they're business software integrations, not personal
He's one of the most secure options on the market, as since it's built for business, it's SOC 2 compliant, and have all the team privacy/security sharing features available

Cons

While Viktor at time uses a virtual computer to get work done, you can't actually access it, like you can with Muse and Grok Bot
If you try using him for things like grocery lists and grocery shopping, you're going to feel like it's the wrong tool for the job quite quickly

Pricing

Viktor is credit-based, so the team just charges a small margin atop of direct LLM costs, so it's similar to using Claude or ChatGPT via credits.

You can get your first month + $100 in free credit ($200 value), by using our Viktor discount code.

Muse Editor's Verdict

What is Muse?

Muse is Meta's new personal AI assistant and it's currently free 👀 Free AI personal assistant? You don't need to tell me twice!

Unlike a normal AI chatbot, Muse can actually complete tasks for you. It can shop, watch deals for you, fill out returns, forms, and about a zillion other things. It's also incredibly easy to use. If you can use Meta or Instagram, you can use Muse. It's just one long chat, and you can even connect your WhatsApp and chat with it right from there.

My Experience with Muse

While I've used my fair share of AI tools for work, this is the first personal assistant I have. Every time something comes up, I tell Muse.

For example, I asked it to let me know when my favorite band will be in town, and to make my Black Friday wish list and monitor deals. My biggest win so far is around shopping.

I gave it a tight set of criteria to help me find a mineral sunscreen that wouldn't leave a white cast. I asked it to find Reels of real users using it too. And it did!

I'm excited to continue to use it.

Key Features

Task Execution

Muse gets its own secure virtual computer and browser. This means it can visit websites, fill out forms, use your accounts with permission, etc.

My husband asked it to submit a warranty claim for a broken device, and Muse handled the process for him. It asks for approval before sensitive actions such as sending something or making a purchase, and you can review what it has done.

Recurring Tasks and Monitoring

Muse can repeat tasks or monitor something without waiting for you to ask again.

You could have it watch for an appointment, track the price of an item, look for tickets, monitor a full class for an opening, or complete monthly administrative work.

Our meal-prep chef needed a simple way to send invoices, so she asked Muse to create and send them automatically on the first of each month. She didn't need to learn an invoicing platform or build an automation, she just told Muse what she needed!
