Show HN: Sal, an LLM-powered educational video creator

I'm a first-year college student who thought it'd be cool to leverage GPT-4 and OpenAI's TTS models to create an assistant that creates an educational "video" on the fly on any topic!

Currently, Sal is an early-stage prototype, but I think there's likely some utility in using LLMs and other AI tech to further the autodidactic side of education.

Let me know your thoughts on the demo!
