STEP 01 of 04~2 min
Attach the document
Open WebUI reads the file on your machine and finds the relevant parts when you ask a question.
Start Open WebUI the way you did in the last lesson and open localhost:8080 ↗. Click the + next to the message box and choose your file, or drag the file onto the chat.
TipBehind the scenes, Open WebUI splits the document into chunks and indexes them with a small model that runs on your machine. That's why it works offline.
