Another possible aspect of it is that probably more and more sites are blocking AI crawlers through e.g. Cloudflare's support for blocking AI crawler and AI agents. This will give them a backdoor to that content through a user's connection.
I am not sure if this is happening, but as blocking becomes more prevalent, having a widely-used browser will help.

I can just see the news story now:
"Oops, we got caught using our customers' internet connections as exit nodes for the largest residential proxy ever to exist, both on pages they visited and ones that they didn't. But don't worry, this was an unauthorized experimental rollout to only parts of the world that we don't have legal nexus in. The program has been halted, and the person responsible has been sacked. Mynd you, møøse bites Kan be pretty nasti..."

Why won't these sites simply block this browser?
xena
I downloaded it to see if Anubis can block it. It lies and claims to be Google Chrome.
jazzyjackson
Because this browser is just chromium and its user agent will be indistinguishable
Zetaphor
It can (and likely will) just transmit standard browser signals. The AI integration is more of a UI layer on top, not something that is being sent in a request header UA string.
That lack of signals in addition to the regular human behavior patterns that something like Puppeteer doesn't have is going to make this practically impossible to block

If such a browser was unavoidable I'd just drop off the web and read books. They can only turn the screws so much.

I hear Ray Bradbury is a pretty good novelist.

Man, I miss the old days, seeing new tech come out and not immediately wondering how the worst parts of our industry are going to turn it into the torment nexus.

I remember the optimism:
Google is launched and it is web directories but…better. It takes a decade to become a monolithic ad-tech company but all is not lost yet, until it becomes the face of enshittification of the entire internet another decade on.
Facebook is launched and it’s this cool way to keep in touch with your friends until that too becomes a monolithic ad-tech company a decade later, and soon after becomes the face of enshittification of social media as a whole, lowering the bar on civility to a subterranean level.
Ditto for Amazon and the enshittification of online retail. And Microsoft with.. whatever the hell you call Windows these days.
What took 10, 20, even 30 years to show up as being bad for society now takes just a couple of years, maybe even less than that. Maybe even straight away.
It’s like the stagnation of Asimov’s Galactic Empire. A bunch of crusty old tech companies, too big to change.

> Yesterday, OpenAI announced Atlas, its AI browser. To the surprise of literally nobody, it’s Chromium with AI slapped on top. Perplexity also has a browser: it’s called Comet, and it also is Chromium with AI slapped on top. Then we have DIA, which is, you guessed it, Chromium with AI slapped on top. I think Opera also has one of those Chromium browsers with AI slapped on top.
The interesting thing is what they "slap on top" of it then. In other words like a browser extension, how do they extend the browser? It's common to have a base model of something and then extend it with options of various capabilities. I don't really understand the complaint here.
The interesting thing to me about OpenAI's browser is how they will handle ad blockers. 95% of ChatGPT users use the free version and OpenAI needs to monetize that.
Building a chromium replacement is a daunting task. in fact microsoft gave up on thiers and adopted chromium for that reason. Chromium is an industry wide open source project like linux for good reason
I'd like a Chromium base model that I can add AI features to that I need. We have a mechanism for that called extensions, but I imagine there are features that require deeper integration with Chromium. We had a mechanism for that called ActiveX on IE and Netscape Plugins on other browsers but we got rid of that for security reasons.
We're at an interesting point in browser development and I'm excited about it

Building on top of a bunch of things works well, and is pretty much what Chromium itself is anyways. Building something "new" that is 99% the old thing so you can add your 1% is a different kind of building, and can't be lumped with the former by default. More powerful extensions is definitely the answer, just not one Google wants to allow.
The main problem with this is if browser A adds feature 1 and browser B adds feature 2 then you don't end up with "Chromium + 1 + 2" you end up with "Chromium + 1" or "Chromium + 2". Repeat for a couple dozen Chromium folks and your single extra feature doesn't look all that enticing anymore. The inverse way of looking at it is "if you're only adding 1% on top of Chromium, it's unlikely to amount to anything worth the average user switching for". Especially since Chrome is starting to push Gemeni natively anyways.
For these reasons, I think Chromium paint jobs are the least interesting thing to happen to browser development in a very very long time. Servo for embedded, Ladybird for "something different", and so on are much more interesting. These kinds of things, as you say, are more to the scale of what an individual browser extension used to be.

I've been very impressed by the open source Ladybird project for several years now. I wasn't up to date and didn't realize it had 8 full time engineers working on it now with project leader Andreas Kling. This is truely more promising than "slapping things on Chromium" and competing with Google Chrome.
I didn't explicity state but was implying that a new plug in archeticture to the open source Chromium project might be an interesting way to add AI features in a more democratic fashion.
Either path still has to compete with what Google does with proprietary extensions to Chrome.
Edit to be clear: Since Chromium is open source, the community could actually collaborate on adding a shared AI plugin architecture to the core project rather than making competing forks. That would solve the fragmentation problem entirely.

>Chromium is an industry wide[...]
But is it though? Feels to me like Google just does whatever it wants. Nobody except Google wants manifest v3. Nobody wants "Web Environment Integrity", etc.
labrador
I agree that Google's control over the Chromium roadmap is a fundamental issue, making "industry-wide" a generous term. Brave (which I use) and other Chromium-forks exist to ensure the community does have its own branch. Brave disables WEI and forked the Manifest V2 code to ensure its built-in Shields and essential extensions (like uBlock Origin, which I also use) remain unaffected by Google's anti-user changes.

To find out what someone truly believes, don't listen to what they say, observe how they act. I don't see how OpenAI's recent actions make any sense from the perspective a company that internally believes it's actually close to unlocking super-intelligence.
Terretta
No, but their actions do suggest they think they're nearing a disruption to both browser and web page: a new way to acquire and make use of information.
Like an information OS for the information cloud.
superjose
I think they need to respond to all the funds they've raised and need to generate money somehow beyond subscriptions.

They are multiple companies in-one. One that is pushing for AGI, model development, one that is trying to build consumer apps and "win" AI applications/platform moat.
aabhay
OpenAI has always had the stance of “commercialize narrow AI that is research aligned with AGI development”. In fact they used to ask this as an interview question — “should we commercialize narrow AI or aim to put all resources into AGI”. The correct answer required you to prove you drank the kool aid and also wanted to make tons of money.
ghjv
Makes sense, I guess. Did you hear that question yourself in an interview, hear it from someone who interviewed, or hear that as a story through the grapevine? and ~when was it asked?
sikimiki
Is there a correct answer?

Genuinely curious - what do people want to see from a new/different rendering engine?
The web is crazy complex these days because it is an entire app platform.
The incentive for anyone building a browser is to use the platform that gives you the best web compat especially at the outset when you don’t have enough users of your app to be able to make big changes to the platform. Even Chrome didn’t start from scratch - it used WebKit!
The Chromium community has built an excellent open platform that everyone can use. We are fortunate to be able to use it.

I think Google has proven with their recent actions concerning android that they really can't be trusted with big, critical open source projects.
bigyabai
The Play Store services are not a critical open source project, though. The AOSP is still intact and maintained in accordance with the licensing.
The application signing backtrack is an issue, but more of a political problem than a technical one. America's lesson here has been written on the wall for years: regulate your tech businesses, or your tech businesses will regulate you.
MYEUHD
Where is the source code for AOSP 16 QPR1?
Where are the security patches of the past couple of months?

> Genuinely curious - what do people want to see from a new/different rendering engine?
It should be fast when rendering HTML/CSS. I don't really care about JavaScript performance, because where possible I switch it off anyways.
It should be customizable and configurable, more than Firefox was before Electrolysis and certainly much more than Chrome.
It should support addons that can change, override, mangle, basically do everything imaginable to site content. But with configurable permissions per site.
It should support saving the current state of a website including the exact rendering at that moment for archiving. It should also support annotations (like comments, emphasis, corrections) for that. And it should support diffs for those saved states.
And if you include "the browser" in that:
I want a properly usable bookmarks manager, not the crap that current browsers have. Every bookmark should include (optionally, but easily) the exact page state at the time of bookmarking. Same for history.
Sync everything to a configurable git repo: config, bookmarks, history, open windows/tabs, annotations and saved website snapshots.
I want easily usable mass operations, like "save me every PDF from this tab group", "save all the pictures and name them sometopic-somewebsite-date-id.jpg" or "print all tabs that started with this search and all sites visited from there as PDF printouts into the documentation folder".
I want the ability to watch a website for changes, so the browser visits in the background and notifies me if anything relevant is different (this could be a really hard thing to get right I guess...).
I want "network perspectives" (for lack of a better word): show me this website as it would look from my local address, over this VPN, with my language set to Portuguese, ..., easily switchable per tab.
I want completely configurable keybindings for everything, like vimperator, but also for the bookmark manager, settings, really everything.
And I want a pony ;)

I think the concerns are not about feature requests but about leveraging embrace-extend-extinguish dynamics to push the web as a whole closer to being locked into dependence on Google as a platform. There are mountains of articles on the topic, ranging from ad blockers to privacy to DRM. But the critiques are old news to anyone who's been following the topic for a while.
eikenberry
I'd like to see browsers support the Gemini protocol and the Gemtext format.
jay_kyburz
Full support for Ublock Origin. Perhaps at the native level rather than as an extension.

> The web is crazy complex these days because it is an entire app platform.
I'd prefer something that's not crazy complex, that's not "an entire app platform" designed and implemented by Google. Google essentially controls the W3C (Mozilla would vanish if Google stopped funding it), and controls the monopoly rendering engine.
Half of websites are better without JavaScript and web fonts, and 99% are just text, images, and videos with maybe a few simple controls. For the other 1% I can fire up Google Chrome and suffer the whole platform.
I want a web rendering engine for the 1%, that does the simple stuff quickly and isn't a giant attack surface around 30 years of technical debt and unwanted features calling itself an "application platform."

I would like scratch made browser to focus on performance.
Chromium browsers eat my RAM and drain my computer battery.
stalfosknight
Try Safari. No browser is snappier or more power efficient.
phplovesong
Its not "AI slapped on top" but AI slopped on top.
I will use an "AI browser" over my dead body.
nextworddev

stalfosknight
Please don't give the pointy-haired boss ideas.
cowmix
This post resurfaced a thought I had. MSFT is really, really pushing AI. It would be really cool if someone attempted, with any of the coding models / agents, to recreate Windows from "scratch". THAT would be very interesting, and useful -- on my levels.
tehryanx
Rolling your own browser is 10x more dangerous than rolling your own auth or crypto. Building on top of chromium is a good thing here.
binarymax
I think the point is: why is OpenAI wasting its time on this? If it's just another channel for billing tokens then OK I guess, but it's not like it's a huge breakthrough.
OpenAI should be the roads, not the trucks. Let other product teams sort out the AI browsers. OpenAI has lots of problems to solve related to models and thats where they should focus. This is a side quest.
ihorcher
This could be a legal loophole to scrape all the data from websites that block you directly. Your users will grab all the data for themselves and you just put some telemetry here and there and here we go, we scrape all the web without even using our own IPs
thelastgallon
So, Atlas, Comet, Edge, Dia, Brave, Opera, etc are all Chromium.
And any browser on iOS uses the safari engine under the hood?
Looks like we are down to two browsers.
SoKamil
>any browser on iOS uses the safari engine under the hood?
Literally every browser on iOS. Up until iOS 17.4 you were not even allowed to have alternative browser engine. And that still holds true outside EU.

I use Orion as my daily driver, mostly because of its Kagi integration.
L3viathan
Firefox still exists.
stOneskull
firefox is the best, and gemini in google search results is enough, for me.
leshokunin
There's Orion. It's not bad, but I don't love it either.
jazzyjackson
Zen is a really nice Firefox fork.
Ladybird is coming along.
jdiff
Zen is an incredibly thin layer on top of Firefox, with some rather glaring performance and battery life issues. Battery life in particular was already not one of Firefox's strong suits. It looks nice, there's some interesting and useful ideas there, but Zen is ultimately "just Firefox" the same way that all of these AI browsers are "just Chromium." Ladybird's the only new kid on the block for a decade.
jimbokun
First, Chromium is also based on WebKit so that means really only one browser engine.
Second, I imagine so many web sites and web applications have, knowingly or unknowingly, made themselves dependent on WebKit or Chromium specific behavior, it's almost impossible to write a new browser compatible with all (or even most) of the web.
glenstein
I'm glad this point is continuing to get hammered home. Because on what feels like a nearly daily basis, I'm still seeing people surprised and learning for the first time that what they think of as a whole browser ecosystem is really just a bunch of things using a Chromium foundation.
But to try and be constructive for whoever's reading and thinking of their next AI browser, I would be impressed by a wholly alternative browser engine, or demonstrations of major capacity to maintain programming upkeep of alternatives on par with the programming capacity supporting Chromium. A big part of the Chromium "moat" as it exists right now is the ability to bring disproportionate resources to bear on browser engine modernization. I would be impressed if AI tools were being used to demonstrably close the gap, because it conceivably could have important implications for getting us away from the browser monopoly problem.
throwacct
Nah.. I'm good. I use brave for daily use and that's it. My family uses safari by default and won't switch over since they're not tech savvy.

This weird solution of storing representations, and not the actual events/data can't age well.
Like flying a plane but instead of logging flight data digitally, you film the cockpit gauges with a camcorder.
To be sure, a browser that retains a representation of every word you read on it, constantly synthesizing a profile on your preferences, using that profile to filter everything you see through a lens that consistently enforces and limits the worldview of a snapshot-of-you - all with a level of data retention that would be controversial for Google but that OpenAI's users will happily opt into, that Palantir and its government clients are likely salivating over, and that is fertile ground for a new generation of ads that bypass pesky things like third-party cookie restrictions - must be exciting to many!
It's just not exciting to me.
