9 Best AI Agents in 2026

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.

If 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.

• 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

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.

• 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.

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.

The actual pricing/cost comes from the credit usage with Claude Tag, as you get an incredibly low limit with just the base plans. But technically, you can get started with the following:

• Team Plan: $20/seat/month (billed annually) or $25/seat/month (billed monthly). Minimum 2 seats, designed for teams of 2-150 people.
• Enterprise: Starts at $20/seat plus usage-based charges at API rates. Best for large organizations needing custom security and controls.

Stilla is an AI assistant that lives across Slack, Linear, GitHub, your CRM, meetings, and the other tools your company already uses. Instead of stopping at "here's what happened," it helps answer, "Okay, what needs to happen next, and where does it need to happen?"

In September 2026, Stilla announced they were acquired by Meta. While they claim the product will still continue to serve it's users, the main focus will be to strengthen Meta's AI products for business.

• 14-day Free Trial: $100 in credits (no credit card required). Best for testing how Stilla actually works and how far the "agent" workflows can go.
• Team: $50/mo ($40/mo annual). Best for technical teams looking to automate workflows and take action across their systems.
• Enterprise: Custom. Best for larger organizations that need unlimited members, advanced security, and tighter control.

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.
