Line Relay
Every movie line leads to another. Start the relay.
Unlike movie quote databases that just let you search, LineRelay chains 34,908 classic movie quotes by meaning. Drop in one line and watch it relay to a quote from a different film that shares its soul, not its words. What makes it different: • Semantic chaining via pgvector — meaning over keywords • Hybrid search picks surprising next quotes • Open source: FastAPI + Next.js + Postgres + Redis For cinephiles and devs curious about vector search in the wild.
Hey Product Hunt 👋
I kept wondering: what if "Here's looking at you, kid" could lead to a line from a completely different film that shares the same feeling? Movie quote sites are search engines — you type a phrase, you get a phrase. I wanted to see how lines echo across cinema.
So I embedded 34,908 classic quotes with pgvector, built a hybrid semantic search to pick the next line, and chained them into a relay. The next quote is never obvious — it shares the soul, not the words.
Drop your favorite movie line below and I'll relay it 🎬
