I had to look Arc up because I forgot what it was. For others confused like me:

Arc was an alternative web browser with novel UX and AI features built-in. The company was acquired for $610 million by Atlassian and development was halted in favorite of Dia, another browser with AI features and novel UX (which I also had to look up)

View on HN

I think development was halted on Arc, and Dia was announced before the acquisition.

If Arc has AI features then I never saw them. Arc was a superb browser, far superior to any of the others due to the care they took over the UX.

There is no AI in it so far as I can tell, and I'm using it right now to type this comment. It's a chromium skin really, of course, but it's great.

One of my favorite parts of Arc was that they already discontinued new features. It’s perfect, I get to open the same tool every day with fresh chromium patches. I would gladly pay for this experience yet they never asked.

Anything else like Arc does too much. This is a true disappointment, coming from The Browser Company

Just migrated to Zen this afternoon using https://github.com/Thinkscape/arc-to-zen, it's ok so far. I tried Zen a few months ago and at the time it didn't feel great compared to Arc (some transitions were not very smooth, some things didn't work just like in Arc) but it's really improved. After just a few hours I don't really feel a difference.

As a bonus it's based on Firefox so uBlock Origin is available.

I saw it mostly in the new tab screen. When you type, there's an option to query chatgpt instead of doing a search/url input. ALso they bundled the Max AI which summarized pages. To me that was only useful to summarize pop culture chat stuff like "Why is XXXXXX getting cancelled?"

the privacy of this one doesn't look so good tbh https://www.diabrowser.com/privacy

Your IP address, IP address-location data, device ID, the pages you visit using Dia and queries submitted, and other “User Content”.

Indeed, doesn’t look good at all.

I was confused because the programming language that Hacker News is written in is also called Arc and I was like "Wait, did PG turn over maintenance to an independent foundation? Are they giving up now? What does this mean for HN?"

I made two additional wrong guesses, the Advanced RISC Computer class of machine firmware and the file archiving utility from System Enhancement Associates. (-:

(Back when the headline was "Arc is Sunsetting". I am so 2 minutes ago.)

Note that Arc had no or minimal AI when it launched; its appeal for so many of us was its refreshing opinionated stance on the browser UX. The AI hype train hit them hard and they tried to pivot to Dia, which leaned fully into AI but did none of the fancy UX things that Arc did. From what I could see online most of the fans they attracted with Arc were turned off by the pivot. It was peak early AI hype, which didn’t help: so much more smoke and so much less fire than there is now.

Dia now does appear now to have many of the Arc UX features. Plus AI.

Sometimes I wish I had the gall to bolt AI on to something and sell it for _half a billion dollars_ only to sunset it a year later.

Arc was already essentially discontinued in favor of Dia when they were acquired. It only received bugfixes.

The raised their seed and series B, some $20 million, before Arc was publicly available. "gall" is a good word.

Also it was YACB (yet another chromium browser), as is the successor browser Dia.

Damn 610m for something they never used, just like the sapphire company Apple acquired.

Something is super, super fucked up with valuation of companies and the profiteering of late stage capitalism for stuff like that to be able to happen.

No wonder lots of people are saying the world feels worse than ever, everything's expensive and it seems in many ways we've regressed rather than "made things better for our children".

Apple didn't acquire GTAT. They were just a supplier.

Ah, in that case thank you for the correction.
