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. Live chat is free with unlimited agents, so you can put chat in front of the whole company without paying per seat as the helpdesk or the workforce grows.
