Show HN: YC idea matcher – Submit an idea and get a list of similar YC companies (yc-idea-matcher.vercel.app)

This project uses semantic search, an advanced search technique that aims to understand the intent and context behind a search query instead of just matching keywords.

It's built using Neon Postgres + pg_embedding and OpenAI for generating embeddings. More details can be found in the repo https://github.com/neondatabase/yc-idea-matcher
