We (Nick, Dens, Denzell, Fede, Drew, Aaryan, and Daniel) have been building HN Discovery, a discovery-focused search engine for Hacker News, in our spare time for the past 6 months and are excited to show it! It adds the following features relative to the existing keyword search interface and preserves the existing ones: - no-JS version (hnnojs.trieve.ai) - site:{required_site} and site:{negated-site} filters - public analytics - LLM generated query suggestions based on random stories - recommendations - dense vector semantic search - SPLADE fulltext search - RAG AI chat - order by descendant count client code (FOSS self-hostable) - https://ift.tt/zLyJhoH engine code (BSL source-available) - https://ift.tt/USkfZWm There is an extended about page with detailed information on features, how much it costs to run, etc. here - https://ift.tt/S9GU8hQ .
