Everything you upvoted on Hacker News, pulled onto your phone and kept there, fully searchable, taggable, and yours to annotate.
HNowledge is a personal archive of all the stories and comments on Hacker News you've upvoted. Sign in with your existing Hacker News account and the app pulls in everything you've ever upvoted and stores it locally on your phone.
FEATURES
- Reads the stories and comments you upvoted into a local archive
- Add a private note to anything, and tag it however you like
- Search through all upvoted titles, comments, and notes
- Filter your upvotes by tag, date, or story type and group them by domain, authors, or month
- Read an upvoted comment in its context right from the app, or navigate to the full thread
- Select any profile and see all their stories and comments you upvoted
- Fully offline: once upvotes are synced, the archive stays on your device
- Export your whole archive as JSON at any time
Please note: this is a read-only archive, not a full Hacker News client. You cannot upvote, submit or comment on any content on Hacker News using this app, and it is not a front-page reader either: it shows what you already upvoted, not what's new.
YOUR ARCHIVE, ON YOUR DEVICE
There is no HNowledge account and no HNowledge server. Your Hacker News login goes to Hacker News and nowhere else, stored in the iOS Keychain. The archive lives entirely on your device and nothing is ever uploaded, analysed, or shared.
HNowledge is an unofficial client and is not affiliated with, endorsed by, or connected to Hacker News or Y Combinator.
Stories and comments come from Hacker News:
