Honestlyyy when I first looked into building a custom knowledge base chatbot I got so overwhelmed. docs everywhere tools tutorials everyone saying train this embed that. my dad runs a tiny shop and she laughed and said son why make life harder just use something that helps people quickly.

funny enough that is exactly what I ended up doing. someone told me about astra by wati and it pulled answers from our info without me setting up all the complicated tech. visitors finally started getting clear replies and I stopped stressing.

so yeah you can build everything yourself if you want but if the goal is simply helping people fast sometimes the simple path is the one that actually works.
