The new toy I've been working on

Video Wiz: Summarize and ask question with any youtube video

Tech stack
- @nextjs
- @tailwindcss & @shadcn UI
- @langchain4j
- OpenAI API
- @vercel for hosting & AI streaming
- @upstash for memory
- @supabase for db & vector store

Took about 5-6 hours to get to this point. Shamelessly copied from multiple starter kits to get here

- TailwindUI Salient template
- Azure ChatGPT
- @a16z companion app starter kit

Learning so far:

- Building chatgpt wrapper is not easy. It took me a few hours to get summarization work
- Langchain devx leaves a lot to be desired
- Need to more ruthless trimming down scope

What's left:

- Adding auth to keep track of chat history
- Adding chat

1 day from launch, stay tuned

@jjen_abel So is it after pricing negotiation & procurement & security? For most of our deal, buyers want to do poc & pilot middle of the funnel, is that worse for the startup?

@pedroh96 Happy Brex customer and fellow YC founder here. How is brex using AI agents for its customer operations (support, sales).

How do you plan to bring innovation on AI agents at brex to cap 1

@ArthurMacwaters You can roll over to a self directed IRA (not roth) and invest in whatever. Or even better do a ROBS (rollover as business startup) and use the money for your next startup

@jasonlk I was at a talk by Meagen Eisenberg today and she said if her marketing team members doesn't use AI to get better, they wouldn't have job in marketing for very long

[Trung Vu @thetrungvu]
