       Show HN: Factual AI Q&A - Answers based on Huberman Lab transcripts
        
       This is a quick prototype I built for semantic search and factual
       question answering using embeddings and GPT-3.  It tries to solve
       the LLM hallucination issue by guiding it only to answer questions
       from the given context instead of making things up. If you ask
       something not covered in an episode, it should say that it doesn't
       know rather than providing a plausible, but potentially incorrect
       response.  It uses Whisper to transcribe, text-embedding-ada-002 to
       embed, Pinecone.io to search, and text-davinci-003 to generate the
       answer.  More examples and explanations here:

       | Huberman Lab and my biggest issue has been that I usually don't
       | have an opportunity to write down most of the suggestions while
       | I'm listening.
       | 
       | I've only done a single search with the tool so far, but it
       | immediately returned the details that I was hoping for, along
       | with context and other relevant mentions of the search terms.

       | Thank you kindly for making and sharing this.

       | From https://youtu.be/hFL6qRIJZ_Y?t=1714:
       | 
       | > An area called the dorsolateral prefrontal cortex ... the

       | these are three brain areas that normally are synchronized in
       | their activities ... that's how it is in a typical person. In a
       | person with ADHD ... these brain areas are not playing well with
       | each other.
       | 
       | I wonder if part of the problem might be the usage of text to
       | speech. Did you consider scraping the transcriptions instead?
       | e.g. with https://github.com/jdepoix/youtube-transcript-api

         | 
         | My guess is that there are more relevant results from the
         | semantic search than I'm including in the context (to reduce
         | costs) and that exact snippet isn't being given to the
         | answering model as context.
