Run It Local in Open WebUI

Your model answers fine. You just cannot talk to it like a person. It lives behind a terminal prompt, or inside a browser tab you rent by the seat and cannot point at your own files. Open WebUI is the missing front door: a chat interface you host yourself, that connects to a model running on your own machine or to any endpoint you already pay for, and that can read your documents instead of guessing. This guide takes you from an empty install to a working private instance that other people can actually use. You will choose an install path and understand what each one costs you, get past the networking problem that kills most first attempts, and learn why the very first account you create matters more than any setting you will touch later. You will connect more than one model and switch between them mid-conversation. You will build a knowledge collection from your own documents and get answers grounded in them. You will build model presets that do one job well, and you will finally get a straight explanation of the four similarly-named extension systems that every other guide blurs together. One chapter is spent entirely on the license, because it changed twice, it is not the permissive license most articles claim, and what it permits depends on a user threshold you need to know before you build anything on top of it. Written for someone who can follow a command and read an error message, but who has never administered a server. Every version number, setting name and license term in this book was checked against the project's own documentation and source, and the places where that documentation contradicts itself are pointed out rather than papered over.
