A knowledge base lets a tutor answer from your own materials: a chapter, a set of notes, a past paper. Upload the documents and the tutor draws on them instead of relying on general knowledge alone.
Adding documents
1. Open My Library from the sidebar and click your tutor to open it.
2. Click Tutor settings in the top right.
3. Scroll to Knowledge base and turn the toggle on.
4. Click Upload documents and choose your files. Supported formats are .pdf, .doc, .docx, .pptx, .txt, .md and .tex, and each file must be smaller than 10mb.
5. To remove a file, click the bin icon next to its name.
6. Click Save changes in the top right.
Showing students where an answer came from
Underneath is a second toggle, Knowledge base citations. Turn it on and each answer shows which of your documents it drew on, with the passage it used. That is worth having on for revision material, so a student can check the source rather than taking the tutor's word for it.
If you expected an answer to come from your documents and it carries no citation, the tutor answered from general knowledge. That usually means the document did not cover the question, or the wording was too far from anything in the text.
Test it
Go back to the tutor and click New chat. Settings changes do not apply to a conversation that is already running, so always start a fresh chat to see them.
