Generic AI can answer questions, but it doesn't know your company. Every time, you have to give it the context.
Because it's inside the company, it already knows how it works, including its people, processes, policies, and data. So you can ask it to do real work, from screening candidates and managing expenses to answering questions and creating reports.
