James here (creator of Hazumi for HN), after years of working on Hazumi for iOS/Apple Watch, I finally brought all the app's features to Web with tons more that I think you're gonna love

Radar

- watch any post for changes, you get a browser push notification

- set a custom topic or select from what's there, when it's posted you get a browser push notification

Profiles

- you can view any profile and browse their latest activity, posts, comments and stats

Feeds

- add custom RSS feeds to your home page

- add an automatically refreshing HN search feed for topics your interested in on HN

Posts

- each post is enriched with SEO metadata pulled from the linked site

- AI summary of the story too

Weekly digest

- an in app weekly newsletter (automatically compiled top weekly stories and their summaries)

Bookmarks

- not much to say here but collect stories and organize them as you want

I'd love to hear what you think, how I can improve it, what you want added

Thanks!

James
