While "vibe coding" is fun for rapid prototyping (especially on frontend-heavy projects), it seems that an under-appreciated use of LLMs might be to have architecture-level discussions about complex problems, making conceptualizing solutions and creating design documents way faster.

Having a tool that turns these sorts of conversations into a living document (technical documentation of sorts), that can be queried and updated as the projects evolves might be a game changer. Bonus points if it can listen in on technical meetings and also parse the codebase.
