AI Browser Dia Launches Publicly on Mac

[MacRumors]

The Browser Company's Dia app is now open to anyone on Mac. It's the first time the AI-powered browser has been widely available since its beta launch in June.

Following on from Opera's Neon, which arrived last month, Dia is another AI-first browsing experience that's centered around tab-based chat functionality. The browser includes Skills, which are a mix of user-created and built-in shortcuts for everyday tasks like planning, learning, writing, and coding. Current Skills include summarization, fact-checking, browsing history analysis, outlining, and productivity planning.

Users can mention tabs in any chat query, add attachments to conversations, and personalize Dia with Memory, which helps the browser understand preferences over time. Meanwhile, students get dedicated tools that turn notes, lectures, and readings into flashcards, quizzes, and custom study guides.

Dia requires macOS 14 or later running on Apple silicon. The Browser Company offers both free and Pro ($20/month) tiers. Free users get access to all core features including chat, custom Skills creation, tab mentions, attachments, and Memory personalization, while Pro subscribers receive unlimited chat usage within the terms of service, plus a 14-day trial period.

Acquired by Atlassian for $610 million last month, the Browser Company says it is resuming weekly updates, and plans to bring Arc browser features to Dia. October's releases include more powerful memory of user tabs, redesigned Dia Skills, and Arc's Focus Mode (CMD-S). Dia is available to download directly from the company's website.

What AI engine is it based on?

 

[UnknownTechGuy]

how much better is this than opera neon?

 

[jdawgnoonan]

I know it is standard at the moment, but 20 bucks a month is steep for consumer use. Soon these types of features are just going to be what browsers have.

 

[chucker23n1]

The one interesting product they had was Arc, but they couldn't find a good business model for it, so they killed it.

Nobody is going to use or even remember Dia a few years from now.

haven't really found AI very useful for browsing, but maybe I'm just doing it wrong

 

[xraydoc]

I'm not sure what an AI-based browser is supposed to do for me. Can someone explain why I need something like this? It summarizes the webpage I'm looking at? Why wouldn't I just read it. I'm not being snarky - I'm legitimately asking what benefits something like this provides.

I've downloaded it, so I'll find out what it can do, I guess...

 

[ignatius345]

Absolutely not

 

[Tig_one]

DOA.

I wonder stuff like this too. I think the idea is supposed to be that eventually AI Agents might run in the browser or something. I personally think that these are products they throw out there and see what people do with them to see what sticks. But honestly, most AI is going to be a commodity and I can’t see myself paying for it.

 

[tkermit]

I wish the AI bubble would pop already... at least it makes it easy to figure out which products to avoid.

 

[Apple-achian]

I'd personallty wait for Apple's in-house full AI implementation in Safari. More trustworthy.

If you care about privacy and security, you may want to steer clear of this product. Too much blind trust involved.

Looking forward to see the techbros weeping when the AI bubble bursts, just like when all their ape jpegs became worthless.

Didn't expect that "software behaves in a deterministic way" was going to be something the industry decided to not be worth it in 2025 XD

AI is the solution to a problem that has not yet been identified. Providers do not know how to finance AI. That is why they are attempting to integrate it into everything.
It is also the current hype, similar to 3D and VR in the past.

So, no. The manufacturers themselves don't know what it could be useful for.

But that's not the point. The main thing is that you subscribe.

Agree with you completely.

The only way I can see it being genuinely useful is if you need to summarize a long web page, or rather than reading a long document, you can ask it a question to get a direct answer.

But outside of that, it's hard to see the relevance.

Might just be my personal limitation...

It won't. Lol. AI will be everywhere in the next couple of years.

 

[zarmanto]

I'm not at all optimistic about anything that falls under this umbrella. What we currently label as "AI" is going to eventually be demoted from that branding to something more like "digital assistant", as the implied promises of AI are left repeatedly unmet. And the universal objective of these ventures -- AGI -- will continue to be perpetually just barely out of reach. Just one more year... one more discovery... one more revolution... one more patent... one more subscription.

Eventually, maybe we as a society will learn to accept that these moderately helpful digital assistants are about all that we're going to get out of it.

I think we will be waiting a long long time from Apple that actually works and actually wows us.

Comparing AI to gorilla NFTs is a bit disingenuous perhaps. NFTs were only there for the purpose of making money, nothing that only serves that purpose can survive.

AI is incredibly useful, its purpose it’s to make life easier for people, it’s intended by-product is to make money for its developers.

Is there a bubble, ABSOLUTELY, but just like the WWW in the late 1990S it will survive and be a force to reckon with, not for all, but many.

 

[bluespark]

Hate AI, but man I miss those days when tabs looked like tabs.

 

[tomtad]

If you're wondering, it stands for Diabolical

Trusted partner = the partner paying them the most.

 

[Ctrlos]

It won't. Lol. AI will be everywhere in the next couple of years.

It will but perhaps in a way many of don't even realise. 10% of the world uses ChatGPT but less than 1.4% of them paying for it. The stock market inflation is to keep investment pouring in so they can keep the lights on. This investment is so high that its artificially covering up the hidden recession at the heart of the US economy and beyond the pumping of stock value, companies aren't seeing a return. It will not end well.

Google have enough income to run Gemini from their ad business but AI summaries are killing CTR putting them into a death spiral. They either pull the AI from search or insert ads into Gemini, instantly making it untrustworthy. Did it find the right answer or the one it was paid to promote?

But, much like the aftermath of the dotcom bust something new will take shape. There individuals and companies out there that will pick up the pieces and create something new and better from it. With centralised models being uneconomical and environmentally challenging it is likely the companies currently investing in locally-ran models will be the winners.

Apple are likely looking at making the next Siri into more of a 'spotlight on steroids' that is built directly into your phone and only needs the internet for web queries. That extra RAM in the Pro models isn't for gaming or the OS. Google is already looking ahead. For the last year they've offered Edge Playground to developers for integrating a 3gb distillation of Gemini ('Gemma') directly into apps that works without the web. If you have an Android phone to test it on its worth giving it a go because its really, really good.

AI will probably be everywhere and in everything but the crucial difference is that it won't be running from one location.

Looks promising useful, and has potential for wide-scale adoption.

En********ation will start in around 18 months. Get it while you can!
