About HN Sieve
HN Sieve runs on a serverless stack (AWS Lambda + DynamoDB) that continuously scrapes Hacker News Show HN threads, feeds each entry to a fine‑tuned LLM for relevance scoring, and stores the enriched metadata in a vector index for fast semantic search. It solves the discovery problem for developers, investors, and product hunters who waste hours sifting through noisy submissions.
The UI is a single‑page web app built with React, offering keyword search, tag filters, and AI‑generated summaries for each project. Users can input a URL, a keyword list, or a natural‑language query; the backend returns a ranked list of projects with title, description, score, and direct links. The system integrates OpenAI’s GPT‑4o for summarization and a proprietary relevance model that updates daily.
Ideal for indie founders, venture scouts, and community managers who need to stay ahead of emerging tools. By surfacing the most promising projects in seconds, teams can cut research time by up to 80 %, accelerate product‑market fit experiments, and prioritize outreach to high‑impact creators.
