Hacker News Companion is a browser extension that produces AI summaries of Hacker News comment threads that understand the thread's structure and highlight the key debates, plus Vim-style keyboard shortcuts for navigating between comments. It works with a user-supplied API key for several AI providers, or fully locally via Ollama, and reuses cached summaries for popular stories. It is meant for Hacker News readers who want to catch up on long discussions quickly.
