what is grapple sensei?

an AI brazilian jiu jitsu (bjj) coach and second brain.

how can i use it?

you can ask bjj questions and get an answer along with timestamped links to youtube sources

how does it work?

1. i scraped, chunked, and embedded (using open ai's embeddings) transcripts of various bjj related youtube videos curated by me.
2. when a user asks a question, embeddings are generated for that question and mathematically compared to all the transcript chunks to find the top most similar ones.
3. these sources are given to the ai as context to generate an answer to the question

tech used

• next.js, langchain, supabase, openai gpt3.5
