This is actually an interesting space, and I think there's a room for such products. Large companies struggle a lot with their knowledge bases, and discoverability is part of the problem (especially when using multiple tools: Confluence, Docs, Chat app, etc.)

The problem here is that there are companies that focus on this area and keep improving their products, while for OpenAI it's one of dozens of tools they launch, so it's hard to believe they'll keep dedicating adequate resources to make this a mature tool that's worth the investment (in form of time and money) for the clients
