ChatGPT

Best overall AI chat app

We love ChatGPT and use it daily.

Go to ChatGPT site

What is ChatGPT?

What really is there to say? ChatGPT was the fastest-growing consumer app in history when it launched. It reached 1 million users in about 5 days after launch and 100 million users in about 2 months after launch.

OpenAI is general artificial intelligence. You can ask it questions, and it'll answer them, like a human. You can ask it to write code for you, and it'll build it, all while explaining the why and how.

Engineering friends of mine are worried that it'll replace their job, and yet they are using it to become a better engineer (using it to teach them different coding languages).

The craziest thing of it all, anyone can use it, and you don't even need to be technical to use it. Just visit ChatGPT here and start asking it questions. You'll be amazed by what it can do. If you're more technical, then be sure to check out the actual API and see where you can fit it into what you're building (I mean everyone else is).

Everyone is trying to build a OpenAI (ChatGPT) into their product right now. It's the closest thing we've seen to magic in an incredibly long time.

ChatGPT Atlas

Best AI Browser for ChatGPT users

We have to say that ChatGPT Atlas has quickly become one of the top browsers on the market. Why? Because it has all of your historic conversations that it can bring right into the browsing experience. It has full context on how you write, think, and what you care about.

As a part of our company onboarding, we now require all team members to work exclusively within ChatGPT Atlas because it helps them work that much faster with the AI chat right within the side bar.

If you view ChatGPT Atlas like more of an upgraded ChatGPT desktop experience, and less of a browser replacement, it's actually a no-brainer for any avid ChatGPT user to use instead.

Go to ChatGPT Atlas site

What is ChatGPT Atlas?

ChatGPT Atlas is a Chromium-based browser built by OpenAI that feels a lot like Google Chrome, but instead of Google Search, you have the full power of ChatGPT available everywhere you go.

Pros & Cons

Pros

Copy Link

Think of ChatGPT Atlas as more of an upgraded UI/UX for the ChatGPT desktop app than that of a full replacement for your primary browser.

If you compare it in that way, then it's a no-brainer to install and use it instead of the ChatGPT desktop app.

For example, clicking on a link mid-chat expands the site to the left-hand-side, with chat sitting on the right. It's just a better user-experience than it popping you out to whatever default browser you have set.

From there you can easily ask additional questions about the site you're on, or even reference other open tabs along with browser history. And depending on how complex of a question you ask, their built-in AI agent mode can even pop in and start navigating and completing tasks for you.

So what is the biggest "Pro" for ChatGPT Atlas? It's that it feels like an upgraded desktop app on all fronts. It just feels "right".

Cons

Copy Link

Once you get used to having your full ChatGPT account everywhere you go, it can become hard to use another browser because you are always missing that personalized experience.

Key Features

Agent Mode

Copy Link

ChatGPT Atlas has an AI agent mode that can navigate the web on your behalf. It has ChatGPT with you everywhere (even highlight some text and tell it how you want to modify it and it'll do it inline right there).

AI Chat Side Bar

Copy Link

Because it's a browser, you also have the ability to @ mention tabs to pull in added context, and it also has deep memory on what you're searching from day-to-day.

The truth is, we experienced a ton of efficiency gains at work once we started using ChatGPT Atlas. Every question gets answered faster. There’s no more copying and pasting context from your browser into a separate AI app. It feels like a constant thinking partner. Our research quality has improved, and we probably use the side chat 20 to 40 times a day.

It even has voice mode built in. It can be a little buggy at times (when it acts up we switch to Wispr Flow) but you can literally think out loud about whatever page you’re on and go deeper with AI right there.

We’re now getting work done faster and require all team members and freelancers to work within ChatGPT Atlas as part of their role with us. If you’re running a business, especially a small team, I think you’ll see output increase just by giving them this browser. Just make sure they’re on a paid account so they don’t hit limits.

Pricing

While Atlas is technically free, the features that you're probably seeing teased all over social media and the marketing videos are actually primarily paid (at least for now).

To unlock their AI agent functionality, you must be on ChatGPT Plus ($20/mo) or higher. The same goes for memory and file recall (prior uploaded documents) as well.

So while Atlas is free, it's a pretty restricted version of it (although the truth is we pay for multiple ChatGPT accounts and find the value way outweighs the cost).

Final Verdict

Do you use ChatGPT? If yes, absolutely install Atlas browser, and just treat it as more of a replacement for the ChatGPT desktop app.

In-fact, use ChatGPT for work and personal, and have 2 separate accounts? Use Atlas to login to one of them, and the ChatGPT desktop app to login to the other one, and boom! You've now got built-in account switching (sorta).

If you're not a paying user of ChatGPT, then I'd recommend you give Comet browser by Perplexity a shot if you want to experience the AI agent mode and other agentic features without purchasing a paid subscription.

Comet Browser

Best free agentic mode option

Comet Browser was one of the first agentic browsers to release, meaning that you can not only talk to the baked in Assistant (Perplexity), but you can have it interact with your tabs, emails, calendar, and even navigate the web for you (as if an assistant took over your screen). It's currently the only totally free agentic browser (at least for now). And while it's not as good as Dia or ChatGPT Atlas, it is the only one that gives truly free access to agent mode.

This makes Comet good specifically for researching and shopping.

Go to Comet Browser site

What is Comet Browser?

Comet Browser is an AI-native browser created by the team over at Perplexity, who has been shaking up the search space. The main differentiator with Comet is that their Comet Assistant is at the core, which gives us a taste of what's coming with the coined term "Agentic Browsing". All that really means is that the assistant not only searches with more context and interacts with your tabs, but it actually clicks around the web for you.

Out of all the AI browsers, I trust Comet the most for deep research where I actually need factual information. The reason is because Comet is the most connected to the internet and it gives you clear citations of where it gets it's information from (while ChatGPT can make things up sometimes). So if I am looking for facts, data, sources, I always open up Comet.

Not to mention, Comet's Android Browser is good in a pinch (although not my main mobile browser). It comes in handy specially when shopping online because I can actually use the AI Assistant and it can look for promo codes (so I can finally shop on my phone), available on iOS and Android.

Comet Browser’s agent mode is completely free, unlike other AI browsers where you need to be on a paid plan to unlock agent capabilities so even if it doesn't become your one and only browser, it's incredibly handy to have on your devices.

Key Features

Comet Browser Assistant

Copy Link

Comet's built-in assistant is what sets it apart from all the best browsers we've covered. It handles the new table-stakes well, with Perplexity at the core, so all the usual search and research functionality is handled.

It can also interact with open tabs, allowing you to essentially target your search and research to a more specific dataset to what you're looking into. But Dia can do this as well, so it's not particularly standout in a browser.

But what does set it apart is Comet gives us the first actual glance at what this coveted "Agentic Browsing" experience actually is, in a non-technical, actually user-friendly way.

What does this mean? Well it can connect into your calendar and email to tell you about important emails (cool, like Google Assistant, right?), but most impressively it can even navigate the web for you.

I'm saying that you can ask it to do things, and it will actually navigate around the page your on, open new pages when needed, and take action as if it's a human you're asking to do something for you.

Examples of what Perplexity Assistant can do

Pricing

Free tier with core functionality (some AI capabilities, some limits)
Pro tier with advanced AI features (e.g. Perplexity Pro/Max), extending further AI and agentic browsing functionality

Perplexity

Best for researching, whether work, student, or personal

Perplexity is the best research assistant LLM on the market, like Google but with better citations.

Go to Perplexity site

What is Perplexity?

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.

Dia Browser

Best for AI power users living in the browser

Dia Browser is effectively the AI version of Arc Browser, developed by the same team.

In-fact, most of the features that made Arc great (like the exceptional sidebar, tab management, and profiles features of Arc), have made their way to Dia, all with a modern AI chatbot experience baked in at the core.

Go to Dia Browser site

What is Dia Browser?

Dia Browser is one of the latest AI web browsers from The Browser Company (the same team who built Arc Browser).

After The Browser Company got acquired by Atlassian for $610M, they were given the full resources to double-down on their AI browser, Dia.

Who is Dia Browser For?

Dia is for those who are super excited about agentic browsers (think of a baked-in AI chat sidebar, that can co-pilot the browser with you at times).

Pros & Cons

Pros

Copy Link

Dia has one of the most performant browsers out of all the current AI browsers on the market.
Backed by the same team as the beloved Arc Browser, much of what made Arc great has been making its way to Dia.
Since getting acquired for $610M, they now have the full backing of a $20B+ publicly traded company (Atlassian), to experiment and build in one of the most expensive and competitive spaces in the market.

Cons

Copy Link

Dia hasn't decided to go the path of Agent Mode (controlling your browser for you), type features that both ChatGPT Atlas and Comet have gone deep into. So if you're looking for that, it's not likely coming.
They can't currently use your actual ChatGPT history, so while their chat experience is beautiful and works well, I do at times wish I had more of the context from my ChatGPT account.
They don't yet have a mobile app for iOS or Android, which feels important for something as core as your browser.

Key Features

Sidebar

Copy Link

The same powerful (optional) sidebar that first put Arc Browser on the market, and that everyone else copied (including ChatGPT Atlas and even Chrome), is in Dia, and more refined than ever.

Skills

Copy Link

If you're someone that likes the idea of being able to have pre-built prompts that can be ran that interact with and take into consideration the content on the page you're visiting, then you'll love their "Skills" functionality.

Pricing

Dia is currently totally free, with an optional $20/mo tier, that unlocks unlimited AI chat limits.

That said, you'd be hard-pressed to hit limits on the free tier, I only hit it once, and I was doing some pretty deep shopping research, referencing dozens of tabs and YouTube video content.

Final Verdict

Dia is one of the leading AI browsers in the space, arguably with the most talented and thoughtful product and design team behind it (and now with Atlassian's backing, nearly infinite resources at their hands).

Dia is definitely worth giving it a try, the only question is really whether or not you're open to switching browsers or not. As that's likely the largest blocker. Although, if you're on this page right now, that's likely exactly what you're looking to do, so yes, Dia is worth giving a shot, especially if you've never tried and AI browser.

Raycast

Best MacOS spotlight search replacement

If you're using MacOS, Raycast is hands-down the best spotlight search replacement available. It's one of those apps that you won't "get" until you use it, but once you use it, you won't be able to live without it.

It's usually the first app we install on a new computer, if that tells you anything.

Go to Raycast site

What is Raycast?

Most people use the native Spotlight search within MacOS, and most are totally happy with it. If that's you, you probably don't care much about this space, but I'm here to tell you that you should.

Search is the main way to navigate the OS, and imagine this search box with superpowers. Do you open up the calculator? Raycast has that built in. Have a separate window resizing/manager tool like Rectangles? Yeah, Raycast does that too.

Just about anything you can think of, Raycast can do, or they have an app/integration for it. I'm not kidding—I literally compressed the image to the Arc + Raycast integration using a Raycast plugin:

Never again do you need to navigate to a sketchy "image conversion" website again—you can now do it all through your favorite ⌘ + Space shortcut via Raycast.

Now for the more technical crowd... I'm here to tell you that it's better than Alfred in every way. It's beautiful, free, has deeper native integrations, and the developer community is next-level.

Skeptical? I hear you—so much in-fact that I've debated (for hours) with just about every single one of my power-user friends about why Raycast is far-and-above better than Alfred. They didn't believe me, fought me tooth-and-nail on it.

And guess what? Every single one of them are now using Raycast (and Arc 😉). They just needed to download it and give it a genuine shot. It does everything better, and looks 10x as good (UI/UX).

It's free, just give it a shot yourself. If you're skeptical, come debate me on Twitter—happy to convince you as well 🦾
