HarmoNova is a Chrome (and Chromium-based) extension that replaces Hacker News with a cleaner, Harmonic-inspired desktop interface, presenting story cards on the left and threaded discussions on the right. It supports Top/New/Best/Ask/Show/Jobs feeds, site-wide search with filters, color-coded reply depths, collapsible threads, comment search and sorting, and customizable themes, typography, and story/comment layouts. Interaction with Hacker News - voting, replying, submitting, and favorites - uses the user's HN session so no separate login is required. Comment editing currently redirects to Hacker News’s original edit page. Optional AI-driven summaries can be generated for either linked articles or the HN discussion using the user's OpenRouter API key; summaries are sent to OpenRouter only when requested.
Installation requires no build: download the release ZIP or clone the source and load the unpacked HARMONOVA folder into chrome://extensions with Developer Mode enabled. The extension runs entirely in the browser without a project-run server or analytics, and the code is open source under the Apache 2.0 license. The project credits the Harmonic Android app for design inspiration but operates independently and is not affiliated with Harmonic, Hacker News, or Y Combinator. Documentation covers a full feature guide, privacy/permissions, contributing, and changelog.
