The content is sensitive by default. A customer might mention an order number. An employee mentions an account, a server name, or a document they cannot open. Self-hosting keeps that inside the boundary you already secure.
The questions repeat. Most helpdesk volume is a short list of the same requests. An AI chatbot grounded in your own runbooks resolves them at any hour and escalates anything unusual to a human with the transcript attached.
Headcount should not gate access. A one-time license means you can put chat in front of the whole company without paying per seat as the helpdesk or the workforce grows.
