Nautilus for Hacker News

AI Summaries & Offline Reader

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Go beyond headlines with cited thread analysis, on-device AI summaries, private briefings, watchlists, offline reading, widgets, and no tracking. Nautilus is an independent reader for Hacker News, built around three ideas: remember what you've read, understand what matters, and give you a private research layer around the discussions you care about. The core experience is entirely free — every feed, your full HN account, on-device AI, offline reading, and every research tool below. No ads. No tracking. No account required to browse. UNDERSTAND EVERY THREAD • Cited camps, the crux, and the one comment worth reading — distilled from the whole discussion, not just the top reply. • Source-vs-HN claims and counter-arguments, every claim traceable to a real comment. • Ask a focused follow-up when you need something more specific. NEVER LOSE THE THREAD • New-comment tracking with a quick-jump banner, plus a searchable reading history. • Discussion Lineage traces earlier submissions and closely related prior threads, so you never miss the real conversation. • Thread Explorer maps huge threads visually — comments new since your last visit, OP replies, saved comments, and search matches at a glance. PRIVATE BRIEFING • A short reading queue built from what you read, save, and follow — refreshed privately, on your schedule. • Choose Quick, Standard, or Deep and Nautilus packs your queue to fit. • Built entirely on-device. STORY RULES • Hide, dim, or highlight stories automatically by keyword, domain, author, score, and more — or collect matches, get notified, or exclude them from your Briefing. • See exactly which rule matched and why, with a test preview before you save. RESEARCH TOOLS • Radar: evidence-backed watchlists for technologies, companies, keywords, and repositories, with every claim cited. • GitHub Context: repo facts, README, and license rendered in Nautilus's own reading view — no login required. • Contributor Context: public HN profile facts and relevant prior posts, with transparent match reasons. No reputation scores, ever. YOUR HACKER NEWS ACCOUNT • Vote, reply, comment, favorite, and submit with your own account. • Optional reply notifications and a daily reminder to check the front page. • Your session lives only in the iOS Keychain. ON-DEVICE AI — PRIVATE • TL;DR, explanations, and translation for comments. • Runs entirely on your device. SYNC & OFFLINE • Optional iCloud sync keeps your library, notes, and preferences current across devices — using your own private iCloud database. • Offline packs for stories and articles, ready for on-device reading. EDITIONS • Restyle the entire app instantly with hand-tuned Editions — new colors, type, and texture. • Several Editions are free. A one-time purchase unlocks the full gallery. BUILT FOR iOS • Command Palette and full keyboard shortcuts with a hardware keyboard. • An iPad Research Workspace that expands to three panes when space allows, for reading, notes, and context side by side. • Home Screen widgets, Live Activities, Spotlight search, and Siri Shortcuts. • A Safari extension that finds the HN discussion for the page you're reading. • Localized into dozens of languages, with Dynamic Type and VoiceOver support. PRIVATE BY DESIGN • No ads. No trackers. No analytics. We don't operate a server that could see what you read. • Hide stories and block users to make your feed truly yours. Nautilus is an independent app. It is not affiliated with, endorsed by, or operated by Hacker News or Y Combinator.
