I rebuilt this entire website by typing messages in Slack.
No page builder. No developer on a call. I described what I wanted, sent a couple screenshots, and watched a custom Shopify theme get built section by section while I answered other messages.
When it finished I just sat there thinking... holy s***.
I don't say that lightly. I built a marketing agency, scaled it past 30 people, ran over $10 million a month in ad spend across roughly 100 clients, and sold it. I have seen every "revolutionary" AI tool. Most are impressive for an hour, then I forget they exist.
So this is my honest review of Viktor after 5 months of using it every single day to run my businesses. Real stories, real screenshots from my own account, the good and the annoying.
Quick note before you read: I first published this back in July, and by October enough had changed that I had to come back and rewrite half of it. That's actually a good sign, and it's a big part of why I rate this thing. More on that below.
One thing up front: there's a referral link in here. If you sign up through it I get credit and you get $200 to start, which is $100 in credits plus $100 off your first subscription. That is not why I wrote this. I'd run Viktor either way. You'll see why.
What is Viktor?
Viktor is an AI coworker that lives in your Slack.
Not a chatbot in another tab. Not a workflow builder. You connect the tools you already use (ad accounts, Shopify, email, analytics, project management) and then you just talk to it like a very capable employee.
It started out Slack only. As of this update you can also just talk to it right in your web browser, the same back-and-forth chat you'd have with ChatGPT or Claude, which is nice on the days you're not living in Slack.
I was skeptical. I'd already tried ChatGPT and Claude for real work, and they're great, but they sit in a separate window waiting for me to prompt them and copy-paste the output back into my actual tools. Viktor does the work inside the tools.
Why I'm not worried about picking the wrong AI
Everybody and their mother is launching a personal AI agent right now. ChatGPT Dots, Meta Muse, Grok Bot. Every one of them is welded to a single company's model. If you build your whole process on top of one and that model falls behind next year, you're stuck. You rip everything out and rebuild your entire system somewhere else. I've watched teams do exactly that and it's brutal.
Viktor doesn't play that game. It sits ON TOP of the models instead of being one of them. So I'm not betting on any single lab staying in front. As new models drop I just get access to them and pick the best one for the job in front of me.
Code, image generation, video, copywriting, heavy analysis... there is no single "best" model for all of it, and the winner changes every few months. In Viktor I just switch. Routine high-volume work runs on a cheaper model, the high-stakes stuff runs on the strongest one available that week. My process never changes. The engine underneath it just keeps getting better, and a one-model agent can't do that.
First impressions
Back to the website. I was paying a monthly fee for a page builder and it always bugged me. So I asked a simple question.
Two messages later it had mapped every page on the site. Then it duplicated my theme into a safe dev version so nothing touched the live site, and rebuilt the whole thing as native Shopify sections. Dark mode, custom fonts, the exact look I wanted.
I killed the page builder subscription. The site you're reading this on was built that way.
The directions are hit or miss. Half the time I give Viktor a lazy one-liner and it comes back and blows me away. Other times I'm too vague and it runs with the wrong idea. Early on it posted something to MY LinkedIn when I wanted it on my business partner's. My fault, I wasn't clear.
Now I treat it like a sharp new hire in week one. Give clear direction on anything new, a quick look before it ships, and after that it just knows. It never made that LinkedIn mistake again.
Who is Viktor for?
Founders, agency owners, marketers, operators. Anyone drowning in work who doesn't want to build a big team to escape it.
If you run lean and think in systems, this is the biggest edge I've found. If you just want a toy to answer trivia, save your money and use a free chatbot.
It runs my ad accounts
My clients care about this one most. I gave Viktor access to my ad accounts and asked it to pull real numbers, not benchmarks off some blog. MY data.
It has eyes on 160+ Google Ads accounts and 17 Meta accounts through the connections I gave it. It pulled portfolio-wide CPM trends, flagged the accounts moving the wrong way, and told me which levers to pull.
This used to be a full afternoon of my time. Now I ask, go do something else, and come back to it done.
One tip: on the heavy analysis jobs I make sure it's running on the best model. Leave it on a lighter one and you can tell the thinking isn't as sharp. Takes two seconds to set.
It forecasts my inventory
One of my brands needed a units-by-product forecast for the back half of the year to plan inventory. Normally a painful spreadsheet exercise.
It didn't guess. It anchored to the real revenue projection, converted to units using the brand's actual AOV, applied last year's seasonal pattern, and split it across the current product mix.
Then it told me its assumptions and caveats without me asking. It showed its work, which is what earns my trust with any of this.
It jumps in before I ask
Viktor watches the channels it's in, and when it spots something it can help with, it just... helps. I didn't ask for this, and now I'd miss it.
Nobody prompted it here. It saw a teammate stuck on a broken automation, understood the problem, and offered a specific fix. That's a coworker.
It's also my pickleball coach
I play a lot of pickleball and I want to compete. So I asked Viktor to be my trainer. Elite level. Mental, diet, physical, all of it. I sent photos of my home gym.
It listed every piece of equipment from the photos, then built the program around ME. It clocked that my wingspan is a weapon at the kitchen line and my pro volleyball background means I already compete under pressure, and programmed around it.
Same coworker that runs my ad accounts runs my training. Still kind of wild to me.
You teach it once, and it's yours
None of that pickleball stuff lives in thin air. The way Viktor actually learns how YOU work is through what it calls skills. A skill is just a set of instructions for one job: when to use it and how you want it done. You teach it once and it reaches for it on its own every time after.
And you don't have to write any of it. You can explain a process in a chat, drop in a doc you already have, or my favorite, record your screen once and narrate what you're doing. Viktor watches the video and writes the skill itself. I've handed it screen recordings of how I audit an ad account and it turned them into a repeatable process I never had to type up.
You can also organize them. My whole pickleball operation is its own section: the movements I like, the rules, how I track progress, my diet, all of it. So when Viktor programs my training it isn't pulling generic advice off the internet, it's building specifically for ME off everything I've taught it.
And it compounds. Every week it knows a little more about how my businesses and my life actually run.
It remembers everything
The context doesn't reset every time. Viktor saves my preferences as we go, so I'm not re-explaining how my business works over and over.
Correct it once and it applies that going forward. Over 5 months it's quietly become the "how we do things" layer across all my companies.
Everything I've connected it to
What makes it click is that it works across every tool I already use, from one place.
Ad accounts, three Shopify stores, email, analytics, project management, my books, my whole Google Workspace. No new dashboard. I ask in Slack and it goes and does the thing in the right tool.
The concept isn't revolutionary. The ease of use is.
An AI that connects to your tools and does the work isn't a brand new idea. Plenty of companies are chasing it. What actually sets Viktor apart is the part everyone else fumbles: it's genuinely easy to use.
Most AI implementation tools are clunky. They still need a developer, a config file, and a week of setup before you get any value. Viktor went the opposite way and built the UX first. Literally anyone can set this up in minutes. It's just clicking obvious buttons.
Want to connect a tool? Search for it, click it, connect. Done. There are 3,000 integrations sitting in there ready to go. And if the one you need isn't listed, you hit "Add Custom MCP" and connect it yourself with an API key. Nothing gets stuck behind a dev ticket or a support queue.
That sounds small until you've fought with the alternatives. It's what made it stick for me.
It ships real apps to a live URL (Viktor Spaces)
This one caught me off guard. Viktor doesn't just build something and hand you a file to figure out. It can build an app, a dashboard, a tool, whatever you describe, and drop it straight onto Viktor Spaces. That means it's live on a real, public URL in minutes.
No buying a domain. No hosting setup. No handing it off to a developer to deploy. You describe what you want, it builds it, and you've got a working link you can actually use or share on the spot.
It's perfect for proofs of concept. Spin something up, test it, send the URL to your team or a client, and only move it onto your own domain when you're ready to roll out the real thing. I've stopped sitting on ideas waiting weeks to find out if they work.
They keep shipping (which is why I'm updating this)
I had to rewrite this post three months after I first published it, and this section is most of the reason.
When I first posted, Viktor lived in Slack and that was it. Since then they added a full web app so you can talk to it right in your browser, ChatGPT style, no Slack needed. They've been rolling out quality-of-life stuff constantly too, little things that add up. You can give your chats custom names now, and there's a small "Viktor is working" tag so you can actually see when it's heads-down on a heavy project instead of wondering if it heard you.
None of these are huge on their own. The point is the pace. The product I'm using in October is noticeably better than the one I reviewed in July, and that's exactly what you want from a tool you're building a business on.
There's also a Slack community where the team actually hangs out, reads what people are stuck on, and ships against it. You can feel it in how fast the gaps get closed. That matters more than any single feature, because it tells you the thing is going to keep getting better instead of getting abandoned.
What Viktor costs
It runs on credits, usage-based. The credits can add up, and if you let it chew on big jobs it'll burn them. Some days I torch 60k on a single heavy push. Here's my actual usage.
I'm running around 300k credits a month. That's roughly $750 to $1,000. If you want to spend less, you can dial the model down on lighter tasks and save.
But the math still maths, easily. I'm doing the work of 3 full-time employees for under a grand a month. Would I hire ONE person who could run my ad accounts, forecast inventory, rebuild my website, manage my team follow-ups AND coach my pickleball for that? Not a chance. So the credits don't bother me.
Plans start at $50/mo and scale with you. You pay for what you use, not per seat.
The bottom line
I sold an agency to get my time back, and it still took me years to actually remove myself from the work.
Viktor is the closest I've come to doing it without giving up the parts I love. I run several businesses in about 20 hours a week now. I'm more present with my wife and kids. And I enjoy the work again, because I do the fun 10% and the other 90% just gets handled.
That's my life, actually better.
So yeah. Holy s***. Go try it.
Viktor review FAQ
What is Viktor?
Viktor is an AI coworker that lives in Slack and does real work in the tools you already use, from ad accounts and Shopify to email, analytics and project management. You give it access and direction, and it executes.
How much does Viktor cost?
It's usage-based on credits. Plans start at $50 a month and scale up. I run about 300k credits a month, which comes to roughly $750 to $1,000. New users get $200 to start: $100 in credits plus $100 off your first subscription.
Is Viktor better than ChatGPT or Claude?
Different category. ChatGPT and Claude answer questions in a separate window. Viktor connects to your real accounts, works inside Slack (or the web app now), acts on tasks, and remembers your preferences over time. It also sits on top of those models rather than being one of them, so you pick the best model for each job. It's the difference between an assistant and a coworker.
How is Viktor different from ChatGPT Dots, Meta Muse or Grok Bot?
Those are personal agents tied to one company's model. Viktor sits on top of the models, so you get access to new ones as they release and use the best model for each task (code, image generation, video, copywriting and more). If you build your whole process on a single-model agent and that model falls behind, you have to rebuild everything somewhere else. With Viktor you just switch models and keep going.
Do I need to know how to code?
No. I built my whole website by describing what I wanted in plain English. If you can clearly explain what you need, you can use it.
Is this review sponsored?
It has a referral link, so I get credit if you sign up through it and you get $200 to start. But I use Viktor every day to run real businesses, and everything here is from my own account. This is genuinely how I work now.
