You’re most likely questioning what occurred. Someday we have been all-in on Arc. Then, seemingly out of nowhere, we began constructing one thing new: Dia.
From the skin, this pivot would possibly look abrupt. Arc had actual momentum. Individuals beloved it. However inside, the choice was slower and extra deliberate than it could appear. So I wish to stroll you thru all of it and reply your questions — why we began this firm, what Arc taught us, what occurs to it now, and why we imagine Dia is the subsequent step.

Constructing Dia
To start out, what would we do otherwise if we may do it over again? Too many issues to call. However I’ll maintain it to a few.
First, I’d’ve stopped engaged on Arc a 12 months earlier. The whole lot we ended up concluding — about development, retention, how individuals really used it — we had already seen within the knowledge. We simply didn’t wish to admit it. We knew. We have been simply in denial.
Second, I’d’ve embraced AI absolutely, sooner and unapologetically. The reality is I used to be obsessed. I’d keep up late, after my household went to mattress, taking part in with ChatGPT— not for work, however out of sheer curiosity.
However I additionally felt embarrassed. I hated a lot of the trade hype (and the way I used to be contributing to it). The buzzwords. The self-importance. It made me pull again from my very own curiosity, though it was actual and deep. You’ll be able to see this in how cautious our Arc Max rollout was. I ought to have embraced my inspiration sooner and extra boldly.
For those who return to our Act II video — after we introduced we have been going to carry AI to the center of Arc — it ends with a demo of a prototype we referred to as Arc Discover. That concept is principally the place Dia and a whole lot of different AI-native merchandise are headed now. That’s to not say we have been forward of our time, or something like that. It’s simply to say our instincts have been there lengthy earlier than our hearts caught up.
Third, I’d’ve communicated very otherwise. We care a lot in regards to the individuals we construct for. At all times have. Saying it “pains me” to have made individuals mad doesn’t actually do it justice. In some moments, we have been too clear — like saying Dia earlier than we had the main points to share. In others, not clear sufficient — like taking too lengthy to reply questions we knew individuals have been asking.
A number of years in the past, a mentor informed me to place a sticky observe on my desk that mentioned: “The reality will set you free.” I do know. It feels like a fortune cookie. Nevertheless it’s served me effectively, time and again. If I remorse something most, it’s not utilizing it extra. This essay is our reality. It’s uncomfortable to share. However we hope you may really feel it was written with care and good intent.
With a purpose to reply your actual questions — why we pivoted to Dia, whether or not we are able to open supply Arc, and extra — I must share a little bit of background from the previous. It informs what is feasible (and never) immediately.
At its core, we began The Browser Firm with a easy perception: the browser is an important software program in your life — and it wasn’t getting the eye it deserved.
Again in 2019, it was already clear to us that all the pieces was shifting into the browser. My spouse, who doesn’t work in tech, was residing in desktop Chrome all day. My six 12 months previous niece was doing college totally in net apps. The macro traits all pointed the identical route too: cloud income was surging, breakout startups have been browser-based (writing weblog posts like “Meet us within the browser”), crypto ran via browser extensions, WebAssembly was enabling novel experiences, and so forth.
Even again then, it felt just like the dominant working system on desktop wasn’t Home windows or macOS anymore — it was the browser. However Chrome and Safari nonetheless felt just like the browsers we grew up with. They hadn’t advanced with the shift. And each of those traits have solely accelerated since. Some firms solely situation enterprise variations of Chrome with new worker laptops (their firms absolutely run on SaaS apps), and Chrome and Safari stay primarily unchanged.
In order that’s why we made Arc. We wished to construct one thing that felt like “your property on the web” — for work tasks, private life, all of the hours you spent in your browser each single day. One thing that felt extra like a product from Nintendo or Disney than from a browser vendor. One thing with style, care, feeling.
We wished you to open Arc each morning and suppose, “That is mine, my house.” And we referred to as this north star imaginative and prescient the “Web Laptop.”
Nevertheless it more and more grew to become clear that Arc was falling in need of that aspiration.
After a few years of constructing and transport Arc, we began operating into one thing we referred to as the “novelty tax” drawback. Lots of people beloved Arc — if you happen to’re right here you would possibly simply be certainly one of them — and we’d benefitted from constant, natural development since principally Day One. However for most individuals, Arc was just too totally different, with too many new issues to study, for too little reward.
To get particular: D1 retention was robust — those that caught round after a couple of days have been fanatics — however our metrics have been extra like a extremely specialised skilled software (like a video editor) than a mass-market shopper product, which we aspired to be nearer to.
On high of that, Arc lacked cohesion — in each its core options and core worth. It was experimental, that was a part of its appeal, but in addition its complexity. And the revealed preferences of our members present this. What individuals really used, beloved, and valued differs from what the common tweet or Reddit remark assumes. Solely 5.52% of DAUs use multiple House frequently. Solely 4.17% use Stay Folders (together with GitHub Stay Folders). It is 0.4% for certainly one of our favourite options, Calendar Preview on Hover.
Switching browsers is a giant ask. And the small issues we beloved about Arc — options you and different members appreciated — both weren’t sufficient on their very own or have been too laborious for most individuals to choose up. Against this, core options in Dia, like chatting with tabs and personalization options, are utilized by 40% and 37% of DAUs respectively. That is the type of readability and rapid worth we’re working towards.
However these are the main points. These are issues you may toil over, measure, sculpt, take away.
The half that was laborious to confess, is that Arc — and even Arc Search — have been too incremental. They have been significant, sure. However finally not on the scale of enhancements that we aspired to. Or that would breakout as a mass-market product. If we have been severe about our authentic mission, we would have liked a technological unlock to construct one thing actually new.
In 2023, we began seeing it occur, throughout classes that felt simply as previous and cemented as browsers. ChatGPT and Perplexity have been really threatening Google. Cursor was reshaping the IDE. What’s fascinating about each — search engines like google and yahoo and IDEs — is that their customers had been doing issues the identical method for many years. And but, they have been instantly open to alter.
This was the second we have been ready for. This was a basic shift that would problem person conduct and possibly result in a real reimagining of the browser. Hopefully now you can see why Dia felt like a no brainer. A minimum of for us and our authentic aspirations.
So when individuals ask how enterprise capital influenced us — or why we didn’t simply cost for Arc and run a worthwhile enterprise — I get it. They’re honest questions. However to me, they miss the forest for the bushes. If the purpose was to construct a small, worthwhile firm with a fantastic group and constant prospects, we wouldn’t have chosen to attempt to construct the successor to the online browser – essentially the most ubiquitous piece of software program there’s. The purpose of this was at all times larger for us: to construct good, cared for software program that would have an effect for individuals at actual scale.
So if Arc fell brief, why construct one thing new versus evolve it?
It’s a fantastic query. And for these who adopted our podcast final 12 months, you’ll know that it’s one we spent the whole summer time grappling with earlier than understanding that Dia and Arc have been two separate merchandise.
For starters, in some ways, we now have approached Dia as a chance to repair what we received incorrect with Arc.
First, simplicity over novelty. Early on, Scott Forstall informed us Arc felt like a saxophone — highly effective however laborious to study. Then he challenged us: make it a piano. One thing anybody can sit down at and play. That is now the thought behind Dia: cover complexity behind acquainted interfaces.
Second, velocity isn’t a tradeoff anymore — it’s the inspiration. Dia’s structure is quick. Actually quick. Arc was bloated. We constructed an excessive amount of, too rapidly. With Dia, we began recent from an structure perspective and prioritized efficiency from the beginning. Particularly, sunsetting our use of TCA and SwiftUI to make Dia light-weight, snappy, and responsive.
Third, safety is on the forefront. Dia is a unique type of product – to fulfill it, we grew our safety engineering group from one to 5. We’re invested in pink teaming, bug bounties, and inside audits. Our purpose is to set the usual for small startups. Which is much more vital in a world of AI, particularly as extra AI brokers come on-line. We wish to get out in entrance.
These are all issues that must be a part of a product’s basis. Not afterthoughts. As we pushed the boundaries of whether or not this actually was Arc 2.0 final summer time, we discovered that there have been shortcomings in Arc that have been too massive to deal with retroactively, and that constructing a brand new kind of software program (and quick) required a brand new kind of basis.
Which brings us to the current.
As we began exploring what would possibly come subsequent, we by no means stopped sustaining Arc. We do common Chromium upgrades, repair safety vulnerabilities, associated bugs, and extra. Truthfully, most individuals haven’t even seen that we stopped actively constructing new options — which says one thing about what most individuals need from Arc (stability no more stuff to study).
However it’s true: we’re not actively creating the core product expertise like we used to. Naturally, individuals have requested: will we open supply it? Will we promote it? We’ve thought-about each extensively.
However the reality is it’s sophisticated.
Arc isn’t only a Chromium fork. It runs on customized infrastructure we name ADK — the Arc Improvement Equipment. Consider it as an inside SDK for constructing browsers (particularly these with imaginative interfaces). That’s our secret sauce. It lets ex-iOS engineers prototype native browser UI rapidly, with out touching C++. That’s why most browsers don’t dare to strive new issues. It’s too pricey. Too advanced to interrupt from Chrome.
ADK can be the inspiration of Dia. So whereas we’d like to open supply Arc sometime, we are able to’t try this meaningfully with out additionally open-sourcing ADK. And ADK continues to be core to our firm’s worth. That doesn’t imply it’ll by no means occur. If the day comes the place it now not places our group or shareholders in danger, we’d be excited to share what we’ve constructed with the world. However we’re not there but.
Within the meantime, please know this: we’re not making an attempt to close Arc down. We all know you employ it and depend on it. Lots of our household and pals do, too. We nonetheless find it irresistible, spent years of our life on it — and whether or not it’s via us or the neighborhood, our hope and intention is that Arc finds a future that’s simply as thought-about as its previous. If in case you have concepts, I’d love to listen to from you. I’m josh@thebrowser.firm.
I wish to finish by being frank with you: Dia will not be actually a response to Arc and its shortcomings. No. Think about writing an essay justifying why you have been shifting on out of your candle enterprise on the daybreak of electrical gentle. Electrical intelligence is right here — and it will be naive of us to faux it doesn’t essentially change the type of product we have to construct to fulfill the second.
Let me be much more clear: conventional browsers, as we all know them, will die. A lot in the identical method that search engines like google and yahoo and IDEs are being reimagined. That doesn’t imply we’ll cease looking or coding. It simply means the environments we do it in will look very totally different, in a method that makes conventional browsers, search engines like google and yahoo, and IDEs really feel like candles — nevertheless thoughtfully crafted. We’re getting out of the candle enterprise. It’s best to too.
“Wait, so The Browser Firm isn’t making browsers anymore?” You higher imagine we’re! However an AI browser goes to be totally different than a Internet browser — accurately. I imagine this greater than ever, and we’re already seeing it in 3 ways:
-
Webpages received’t be the first interface anymore. Conventional browsers have been constructed to load webpages. However more and more, webpages — apps, articles, and information — will develop into software calls with AI chat interfaces. In some ways, chat interfaces are already performing like browsers: they search, learn, generate, reply. They work together with APIs, LLMs, databases. And individuals are spending hours a day in them. For those who’re skeptical, name a cousin in highschool or school — pure language interfaces, which summary away the tedium of previous computing paradigms, are right here to remain.
-
However the Internet isn’t going wherever — at the very least not anytime quickly. Figma and The New York Instances aren’t changing into much less vital. Your boss isn’t ditching your group’s SaaS instruments. Fairly the alternative. We’ll nonetheless must edit paperwork, watch movies, learn weekend articles from our favourite publishers. Mentioned extra immediately: webpages received’t get replaced — they’ll stay important. Our tabs aren’t expendable, they’re our core context. That’s the reason we predict essentially the most highly effective interface to AI on desktop received’t be an internet browser or an AI chat interface — it’ll be each. Like peanut butter and jelly. Simply because the iPhone mixed previous classes into one thing radically new, so too will AI browsers. Even when it’s not ours that wins.
-
New interfaces begin from acquainted ones. On this new world, two opposing forces are concurrently true. How all of us use computer systems is altering a lot quicker (as a consequence of AI) than most individuals acknowledge. But on the similar time, we’re a lot farther from fully abandoning our previous methods than AI insiders give credit score for. Cursor proved this thesis within the coding house: the breakthrough AI app of the previous 12 months was an (previous) IDE — designed to be AI-native. OpenAI confirmed this concept after they purchased Windsurf (one other AI IDE), regardless of having Codex working quietly within the background. We imagine AI browsers are subsequent.
That is why we’re constructing Dia. It’s the alternative to chase the product of our authentic ambition: a real successor to the browser — possibly even the “Web Laptop” we’ve been constructing towards all alongside — solely in methods we couldn’t have predicted.
To be clear, we’d fail. Or we’d partially succeed however not win. We nonetheless assume we don’t know. However we’re assured about this: 5 years from now, the most-used AI interfaces on desktop will change the default browsers of yesteryear. Like immediately, there’ll most likely be a couple of of them (Chrome, Safari, Edge). However the level is that this, the subsequent Chrome is being constructed proper now. Whether or not it’s Dia or not.
The Browser Firm is a group that assembled for the prospect — nevertheless slim — to construct one thing that rewired how we use our computer systems. One thing that may, simply would possibly, be utilized by lots of of hundreds of thousands. A bit of software program that really shapes how individuals dwell and work. Not simply an app, however an Web Laptop. That’s what drew us in. And that’s why we’re happy with the choices we made.
Dia will not be your type. It could not land straight away. However that is nonetheless us. Being ourselves. Constructing the type of factor we’d wish to use. Absolutely conscious that we could be incorrect. However doing it anyway. As a result of we predict the intent issues. And we predict that’s what received us this far.
That is our reality, and we sincerely hope that you just’ll like what comes subsequent.
– Josh
P.S. For these of you who do wish to strive Dia, we’re excited to open entry for Arc members subsequent, as the primary enlargement of our alpha past college students.
