What HN said
What people liked
Clean, calm design
From 3 comments
This is one of the cleanest email UIs I’ve seen in a while. Feels calm, which is rare for email.
ozerk on HNI'm no expert in this niche but I really do like the design of your project. Great work :)
selixe_ on HNThis is beautiful product design. I will say, I do wish there was a conversation list when looking at folders--having conversations listed on the sidebar can get a bit busy.

Love the social feeling of UX. I screen through 100s of emails every day and if you are interested in some pointers for potential uses I would die for on our current corporate…

hirako2000 on HNPlease I’d rather have a bad mobile view than a blocker! I know it seems bad but you can always just tell the user to zoom out, a mobile view is coming!

Sidebar navigation confusing; INBOX not clickable
From 2 comments
I find the sidebar very confusing. I can not click on the INBOX folder for example.
kwanbix on HNYeah I'm with you, that was the first thing I clicked, and... nothing.

Hard to load on Android even with desktop mode
From 2 comments
On Android, you need to request the desktop version, rotate the phone to landscape, and refresh; assuming you have a tall enough screen (in px). If it was like Cursor with BYOK,…

hirako2000 on HNI think a mobile version should be your sole focus. Look at it that way, emails are in fact better managed with traditional, deterministic tools. Can move things around, labels,…

Why build a new program instead of contributing to an existing one?

Why creating a new program instead of contributing to an existing mature one? Also, I cannot open your website, does not seem to work without JavaScript.

Is the backend started?
From 1 comment
I am user of Arc(even now!) and I really love it. Feels different in a good way. I can see it's PoC, but have you touched backend even in concept?

Well done! I do hope AI will really allow folks to build products with better UX. The problem traditionally is that the UX gets "stuck" - gmail, google maps, they cannot really…
