7 Best AI Chatbots in 2026

If you've written off the entire AI agent category because nothing has actually stuck, I get it. I roll my eyes when I see a "new AI employee" product now...

But then I was introduced to Viktor and something seemed different. People in the comments seemed to genuinely love it. It intrigued me enough to download it.

Viktor is an AI hire that lives in your Slack or Microsoft Teams workspace.

Viktor feels like having an unfair advantage in our business (like imagine having access to ChatGPT or Claude before the rest of the world 😅).

That's because he reads your channels, understands the work is being done, and will jump into a thread and say "Hey guys, want me to take on XYZ task?".

For me, the first time this happened was when he identified when we were about to post a YouTube video and suggested he gets the description ready (our descriptions are quite complicated since ever URL has to be specifically setup with UTM data and specific links).

It was a task I always dreaded doing, and equally dreaded the idea of delegating it because of the high room for error. I also did not have time to even think through working with Claude or ChatGPT on how to delegate it.

But Viktor walked me through the steps of what he needed to complete the task. He asked for the transcript for timestamps, he pulled the right links from our website on his own, and formatted all the UTMs based on how we did them in other videos (I didn't even give him the link to our channel or anything!).

He came back with something that was 90% right on the first try. No hand-holding, no lengthy explanation of our processes, no "here's a 10-step guide to how we do UTM tracking." He already knew the foundational stuff. We just filled in our preferences as we went.

And that experience repeated itself across our whole team. Our CEO started using Viktor for strategy and ops. Our head of engineering started using him as a technical collaborator. All of that happened organically, without anyone suggesting it. Viktor just showed up differently for each person based on what they needed. That's the thing that made us look at each other and go "okay, this one's real."

Genuinely, if you use Slack or Teams, this is a tool you gotta try 😅

Viktor doesn't wait for you to come to it. He reads your channels, figures out what's happening, and comes to you with specific things he can take off your plate and how he would approach each one.

He asks for what it needs rather than making you figure out how to explain everything. I noticed it's removed a huge cognitive load.

Viktor actually does work. He can fetching pages from any website, pull data from connected tools, cross-reference sources, and come back with a finished output.

For engineering teams this goes even further: Viktor has its own cloud computer, so he can write code, run it, and deliver results without any setup on your end.

Viktor remembers your preferences across sessions and can set up automations that run on a schedule just by being asked. No Zapier, no workflow builder. You just tell Viktor what you want and what time and he handles it.

Over time it starts becoming the process layer for your business, which is honestly where it gets really exciting.

• Free: $100 off + $100 additional credits if you use our Viktor discount code (exclusive to Efficient App readers). Enough to meaningfully test whether it fits before committing.
• Team: $50 per workspace per month. Includes 20,000 monthly credits that refresh automatically.
• Enterprise: Custom pricing. Adds a more powerful underlying model, invoicing, security review support, SLA guarantees, priority support, and dedicated onboarding.

Claude is an AI assistant built by Anthropic, designed for professionals and operators who need more than a generic AI response. It tends to follow complex instructions more completely, sounds less generic, and holds onto more context when you give it a lot to work with. There's also Claude Code for developers and Claude Cowork, a desktop agent that works with files on your machine.

I'll be honest, I resisted trying Claude for a while. I'd been using ChatGPT for two years and it knows me and my writing style incredibly well. Every time I tried Claude before really committing to it, I was disappointed because it just lacked that context, and I'd walk away thinking "I don't get what everyone's talking about!" But the hype kept coming from people I respected, so I couldn't shake the feeling that I was missing something.

What changed it for me was exporting all of my writing instructions from ChatGPT and loading them into Claude as a skill. After that, the experience improved dramatically. Claude started asking better questions and the writing output got a lot closer to what I actually wanted. Now I find myself reaching for Claude specifically when I'm doing deeper writing work. It pauses to ask clarifying questions more than ChatGPT does, and it genuinely seems to honor the context I've given it rather than just acknowledging it and moving on.

Is that because Claude is naturally more thoughtful, or because my prompt told it to ask more questions? Honestly, hard to say. Without the skill loaded in, my earlier experience was nowhere near as impressive as the internet made it sound. So if you're going to try Claude and you already have a strong writing brief (or any other brief) somewhere, move it over before you form an opinion.

Where it still falls short is the surrounding product experience, the Chrome extension, the cross-device memory in Cowork. Those feel like areas where ChatGPT has just gone a lot deeper on the day-to-day user experience, and you notice the gap when you hit them. For now I'm keeping both, especially because I use ChatGPT Atlas for browser work.

• Free: Limited access, good for testing the product before committing.
• Pro: $20/month. This is the tier most founders and operators will want. Gives you access to the full model and the features that actually matter for daily work.
• Max: $100/month. Higher usage limits and more capacity for longer, more intensive sessions. Worth considering if you're hitting limits regularly.
• Team: $30/month per user (minimum 5 users). Adds collaboration features and admin controls for teams.
• Enterprise: Custom pricing. Expanded security, compliance, and deployment options for larger organizations.

Littlebird is an AI assistant that actually knows what you're doing, from your meetings (via their AI note taker), calendar, email, and actually pulling context from on-screen activity. You can just ask, "What did I do today?" and it answers you, but the same always-there "layer" is also what gives us pause. We see that vision here and know that the best AI tool will be the one that has the most context.

My workdays are so messy... Constant Slack messages, hundreds of open tabs, quick decisions, context switching nonstop. Littlebird acts like a second brain that’s been there the whole time, so instead of relying on memory, you can just ask it for whatever someone said, or something you saw.

It's been especially nice for those "I swear I saw this somewhere" moments or when I'm trying to recall what actually happened outside of formal meetings.

But, it's a given that in order to have all the context to provide you those useful answers means it's more invasive. So you do have to get comfortable with how much it sees and be mindful of excluding sites in your settings. Compared to tools like Granola or even ChatGPT, Littlebird is less about doing one thing really well and more about becoming that always-on memory layer across everything you do.

• Basic: Free. Best for those wanting to test the product and see if the context-aware approach actually clicks for their workflow.
• Plus: $17/mo. Best for people who want more depth, more routine usage, and plan to use Littlebird as an everyday assistant.
• Pro: $100/mo. Best for those who need significantly higher usage limits or like advanced intelligence and want early access to feature releases.

If you're comfortable with Littlebird having access to your on-screen activity, then you'll immediately see what makes this AI tool special.

It's one of those tools that is too intriguing not to use.

Definitely grab it for free, and worth locking in the Littlebird discount now if you ever want to upgrade in the future.

Perplexity is an AI-first search engine that replaces Google with direct answers pulled from the web.

We like to use it when doing deep research that we need sources from the internet. It pulls from multiple sources in real time, making it one of the best tools for researching topics online.

One of the main benefits of Perplexity is that it gives you access to multiple LLMs in one place, so you can switch models depending on what you're trying to do.

That said, we find it's much better for internet research than deep reasoning. It's strong at finding and summarizing information with sources, but not as strong as other LLMs for complex problem-solving, math, or advanced reasoning tasks.

Perplexity also offers its own web browser, Comet (an alternative to Chrome), where you can use Perplexity as your default search engine and experiment with AI agent-style browsing features.
