knowledge articles and NowAssist generative AI

[MFuchsloch]

Hello. We have been working to update knowledge articles to work with NowAssist in accordance with what was recommended here: https://www.servicenow.com/community/knowledge-management-articles/best-practices-to-use-your-knowle...

NowAssist is being implemented and I am now hearing that some coworkers think we do not need knowledge articles at all, and NowAssist generative AI can work just reading published pdf, like policies,etc. Does anyone know if there is truth to this? Will NowAssist give quality results without corresponding knowledge articles?

To clarify, I'm not referring to knowledge for case agents, I'm referring to knowledge for all employees on HR-related topics.
