ClippyGPT - How I Built Supabase’s OpenAI Doc Search (Embeddings)

Supabase hired me to build ClippyGPT - their next generation doc search. We can ask our old friend Clippy anything you want about Supabase, and it will answer it using natural language. Powered by OpenAI + prompt engineering. In this video I will be showing you exactly how I did this, and how you can do the same in your projects. We'll be covering: Prompt engineering and best practices Working with a custom knowledge base via context injection + OpenAI embeddings How to store embeddings in Postgres using pgvector Supabase blog post: https://supabase.com/blog/chatgpt-sup... pgvector extension: https://github.com/pgvector/pgvector Generate embeddings implementation: https://github.com/supabase/supabase/...
