Best AI Agent Platforms at a Glance
AI Agent Platform Overview
What is an AI Agent?
What is an AI Agent?An AI agent is an AI that doesn't just answer questions. It actually goes and does work for you.
When you use an AI chatbot like ChatGPT or Claude, you ask it something:
- It gives you an answer → you have to do something with that answer
But with an AI agent:
- You tell it what you want done → it goes and actually does it → comes back with finished work
It's like delegating to an employee, but that employee is AI.
Best AI Agent: Who Wins?
Best AI Agent: Who Wins?For a long time, I kept hearing about AI agents and I was always excited to give them a shot.
But every single time I tried one though, I'd end up in this rabbit hole opening Claude or ChatGPT, which would ask me to open up my terminal, messing with settings, and then two hours later I'd have nothing to show for it. Just wasted time.
Then I tried AI agents like Sintra, and it was the opposite problem. They'd suggest a million things they could help with, but the moment you asked them to actually execute? Nothing. They couldn't pull it off.
So I was left with a bunch of suggestions of ways to improve, with no time to actually get to them all.
Then, finally, I tried Viktor. And it just worked...like, immediately.
The second we added him to our Slack, he showed up and was like, "Hey, I read your channels, I see what you're all working on, here are the things I can take off your plate." And he wasn't asking in some generic way, he was specific!
Within the first hour he was like, "I see you're about to publish a YouTube video, want me to write the description and timestamps and handle the links?"
For our engineer, he jumped into the chat and suggested a way he could fix a problem he was working on.
That's the moment I went from "yeah, AI is getting better" to "okay, this is actually insane. It's here. It's real."
With that, Viktor is hands down the best AI tool and agent I've ever used.

Viktor
Best overall AI agent
Best overall AI agentWith all the AI tools that come our way, it's getting harder to get genuinely excited about anything. But when we tried Viktor, we immediately looked at each other and said, "We need Viktor in our business. This is amazing!"
Our entire team adopted Viktor faster than any other tool we've ever introduced, and honestly, I've never seen anything quite like it.
What is Viktor?
What is Viktor?Viktor is an AI agent that lives in your Slack workspace and actually helps your team get work done. He's not like other AI tools that just answer questions or suggest things.
He goes out and does the actual work. He writes things, finds information, runs code, fixes problems...all without you having to babysit him or figure out how to use some complicated tool.
Who can benefit the most from it
Who can benefit the most from itIf you're running a small team with people doing different things (engineering, marketing, operations, finance, etc) Viktor helps all of them.
You need a Slack workspace and a team for this to work. If you're solo, this isn't for you. But if you have a team of at least 2+ people, you need Viktor in your life.
Pros and Cons
Pros and ConsPros
- He onboards himself. No setup, no learning curve
- He actually does the work, not just suggestions
- He owns entire processes, not just single tasks
- You can build skills by just telling him what to do in plain language (across multiple tools)
- He remembers everything and gets better over time
- You control what he can and can't do (security is great)
- Works with over 3,000 tools and apps
Cons
Cons- You need a Slack workspace (not for solo users)
- Credit-based pricing means costs add up if you use it a lot
Key Features
Key FeaturesProactivity
ProactivityThe thing that feels genuinely different about Viktor is the proactive side of it. It’s not just waiting around for me to remember what to ask.
We’ll be talking about something in Slack, some time will go by, nobody’s responded, and Viktor will jump in like, “Hey, I can do that thing if you want me to.”
That part is kind of amazing because it feels like having this extra employee in the background who actually follows through, reminds people at the right moment, and catches things in the flow of work without me having to constantly manage it.
Security
SecuritySecurity was honestly my main concern at first, because with a tool like this my immediate reaction is: okay, this is incredible, but how does this end badly?
What made me feel better is that we could be really specific about permissions.
We only give it read access to GitHub right now, I can control who on the team has access to what, and if someone asks it for something they shouldn’t see, it respects that boundary (I've tried asking it about my co-workers DM's just to test the limits 😏).
That made it feel much more usable to me because it’s not just powerful, it actually has the restrictions you need.
Context / Integrations
Context / IntegrationsViktor works with 3000+ tools. So if you've been feeling limited by tools that don't have a Claude or ChatGPT MCP connector, Viktor will be your best friend.
You can not only get it to search across all tools you can get it to take action in different tools.
Pricing
Pricing- Free: $100 in credits to test it out. That's enough to really try it.
- Team: $50 a month per workspace with 20,000 credits. Most teams use around $200-$300 a month, which is less than paying someone for a day of work.
- Enterprise: Custom pricing with more powerful features and dedicated help.

Claude Tag
Best AI agent for existing Claude team & enterprise accounts
Best AI agent for existing Claude team & enterprise accountsClaude Tag is useful if you're an engineering team that is already on a team or enterprise Claude subscription (you need 5 seats or more). While it's useful for coding, we don't love that it only has memory per-channel.
That said, we prefer to use Viktor as our Slack AI hire (he works in Microsoft teams too).
What is Claude Tag?
What is Claude Tag?Claude Tag is Anthropic's AI teammate that lives in Slack. You can tag @Claude directly in a Slack thread and delegate work where the rest of my team can see the context and output.
Our team has been using Viktor, so when Claude Tag came out we were curious to see how it compared, but were hit with quite a bit of friction just to try it out.
To use Claude Tag you need at least a 5-team seat of Claude. We have 3 Claude seats that the team signed up for individually, so instead of jumping into using Claude Tag, we had to first untangle our admin and billing logistics (not to mention pay for extra seats we don't need at the moment).
Once we got in, we noticed that Claude Tag doesn't have persistent memory across channels. You get one Claude Tag per channel. Likely makes sense for enterprises, but for our team this is a bit of a bummer.
For example, what we discuss in our SEO channel, often impacts Engineering and vice versa. Viktor sees both, so can answer engineering questions with much more context. But with Claude Tag, we end up needing to re-explain things twice which is exactly the kind of burnout that we're trying to avoid by bringing an AI tool right within Slack.
Right now, I'd mainly recommend Claude Tag for engineering teams or enterprises already using Claude and want help with collaborative coding and problem solving.
Pros and Cons
Pros and ConsPros
Pros- Powerful for coding
- Easy setup if already on Team/Enterprise subscriptions with Claude
Cons
Cons- Minimum 5 seats means $125/month baseline
- One Claude instance per channel, so no cross-channel memory
- Minimal integrations with third party tools
- Doesn't work as well as Viktor for work outside of coding
- Requires Slack
Key Features
Key FeaturesCoding and Code Review
Coding and Code ReviewAnthropic's own team says they use Claude Tag to write 65% of their code.
The AI can inspect your codebase, pull in deploy context, compare what changed, and identify the root cause when something breaks.
Channel-Specific Context
Channel-Specific ContextYou get one Claude Tag per channel. It doesn't hop across channels, which is intentional for privacy but we find this loses the connective context across all channels. With more privacy, it becomes less helpful.
Pricing
Pricing- Team Plan: $20/seat/month (billed annually) or $25/seat/month (billed monthly). Minimum 5 seats, designed for teams of 5-150 people.
- Enterprise: Starts at $20/seat plus usage-based charges at API rates. Best for large organizations needing custom security and controls.

ChatGPT
Best if you're already paying for ChatGPT
Best if you're already paying for ChatGPTCan one really live without ChatGPT these days? It's undeniably one of the best AI tools available. We have four subscriptions in our household alone: one each for personal use and one each for work. At this point, it's more of a family member whose available 24/7.
What is ChatGPT Agent?
What is ChatGPT Agent?ChatGPT Agent is a mode inside ChatGPT that can reason, research, and take actions for you.
Instead of only answering questions, it can use tools like the browser, uploaded files, connected apps, and spreadsheets to complete more complex tasks.
When I tested agent mode, I was honestly quite disappointed. When I compare it to something like Viktor where there's absolutely no setup, no prompting, no procedure to write (it just KNOWS what it needs to do), ChatGPT Agent felt like what I used 1-2 years ago with other AI employee tools.
The result? I haven't continued to use it after the first day.
That said, if you're already paying for ChatGPT Plus or Pro, it doesn't hurt to experiment. You can build something useful for a narrow, repetitive task.
But if you're looking for an AI agent that actually joins your team, takes proactive action, and doesn't need you to hold its hand? You'll want something purpose-built for that.
Pros and Cons
Pros and ConsPros
Pros- Chat interface makes it easy to use
- Agent templates give you a starting point without building from scratch
- If you're already paying for ChatGPT, agents are included, no extra cost to experiment
Cons
Cons- Not proactive. You always have to go to it and prompt it, which defeats the purpose of an "agent"
- Setup is clunky: you have to write SOPs, connect apps, configure everything manually
- Everything lives inside a chat interface, which limits how agents can interact with your actual workflow
- The whole experience felt like where the AI agent space was a year or two ago — not the future
Key Features
Key FeaturesCustom Agent Builder
Custom Agent BuilderChatGPT now lets you create agents by chatting with it. You describe the role, connect apps (Slack, Google Drive, Gmail, Linear, and more), upload reference files, and define how the agent should behave.
It's essentially giving ChatGPT a job description and standard operating procedure.
While you have templates as a starting point, we found the actual outcomes a lackluster and did not end up incorporating it into our workflow.
Codex for Engineering Teams
Codex for Engineering TeamsCodex is where things get more interesting from an agent perspective, specifically for engineering teams. It can work through coding tasks autonomously and return pull requests.
But it's built entirely to code. It's not going to help your marketing team draft content, give your CEO a cross-department report, or manage follow-ups across your business.
Pricing
Pricing- Free: $0. Limited access to GPT-5.5, no agent mode. Fine for trying ChatGPT as a chatbot, but you won't get agent capabilities here.
- Plus: $20/mo. Includes agent mode, Deep Research (10/mo), Codex, and Sora. This is where most people should start if they want to experiment with ChatGPT agents. The 40-message agent limit can feel restrictive if you're a heavy user.
- Pro: $100/mo or $200/mo. Higher usage limits (5x or 20x Plus), GPT-5.5 Pro, and up to 1M-token context at the $200 tier. Worth it if you're hitting Plus limits daily, but that's a steep price for agent capabilities that still require manual setup.
- Business: $20–$25/seat/mo. Team workspace with admin controls, SSO, and no training on your data. Agent mode included. Makes sense for teams already using ChatGPT who want to standardize across the company.
- Enterprise: Custom pricing, 150-seat minimum. Full governance, HIPAA, audit logs. If you're at this scale, you're likely evaluating dedicated AI agent platforms alongside ChatGPT anyway.
Sintra AI
Best for non-technical business owners
Best for non-technical business ownersSintra is built for non-technical business owners who have very little knowledge of how to use AI and want a very easy introduction. Sintra's AI "helpers" are like digital consultants that give you ideas fast, without needing any prompting making it super easy to use.
Would we recommend it to more serious business owner who already uses tools like ChatGPT? No. For serious operators, it more so feels like playing a business-themed video game.
What is Sintra AI?
What is Sintra AI?Sintra is an AI-powered business assistant for people who have very little experience using AI but want to dabble more with it. Instead of you prompting the AI, Sintra's "helpers" ask you simple questions, review your website, and proactively suggest business tasks like improving web copy, writing email sequences, or creating content calendars. It’s designed to make AI feel fun and easy for overwhelmed business owners.
Pros and Cons
Pros and ConsPros
Pros- Extremely easy to use, no prompt engineering needed
- Gamified onboarding, feels more like a game than a tool
- AI Helpers are proactive, they suggest work rather than wait for your input
- Gets better the more it learns about your business
Cons
Cons- Underwhelming execution, the work it "does" is 20–30% usable at best
- Not for serious users, feels very “kiddish”
- Data sensitivity concerns, it asked deeply personal business questions that we did not feel comfortable answering
- Short-lived value, after the first day of using Sintra the novelty wore off
- No free tier, you pay upfront to try it (although you can request a refund within the first 2 weeks if you're not impressed)
Pricing
Pricing- $97/month with an ongoing 60% off discount
- We signed up with the monthly tier and upon creating an account, we were immediately offered a 70% off annual discount

OpenClaw
Insecure general AI assistant
Insecure general AI assistantOpenClaw lets you run an AI agent on your own computer that can control your apps and files, but everyone with security experience says it's a huge risk and not safe for anything important. If you're a builder or hobbyist who wants to experiment on a spare device and don't care about privacy or security, it could be a fun project.
If you run a real business or have anything to lose, you should absolutely avoid it until a secure version exists.
What is OpenClaw?
What is OpenClaw?OpenClaw is an experimental AI agent that can do tasks for you. Unlike ChatGPT or Claude, it can take actions across anything on your device. Your folders, your browsers, tools, etc.
However, it coms with serious security risks. Being upfront, I have not personally installed OpenClaw on any of my own devices. I’ve spoken to a lot of people who have used it, including my father, who has worked in cybersecurity for over two decades and has installed it 6 or so times by now (more about his experience in our full OpenClaw Review).
The consistent theme from everyone I trust is this: no one feels fully confident that their setup is actually secure.
Right now, the risk just doesn’t match the reward.
