If you want to build something like this yourself, we sponsored Greg to create a video detailing all the steps: https://www.youtube.com/watch?v=Yhtjd7yGGGA

Also special shoutout to pgvector (https://github.com/pgvector/pgvector), which is used to store all of the embeddings.

Note that pgvector isn't supported on any of the large cloud providers' hosted Postgres offerings, other than Supabase. https://github.com/pgvector/pgvector#hosted-postgres has instructions on how to add your voice to request it to be added!

(It does seem that the ancient https://github.com/eulerto/pg_similarity is supported by RDS and Google Cloud - but it's hard to tell whether attention was paid to its performance characteristics with nearly the rigor that pgvector seems to have been designed.)

This is so great! Thank you, and Greg if you read this well done on an excellent video and project

Thanks! I've a had a blast working with Supabase on this, glad to hear that you find it interesting!
