Highlight the clause first, *then* pick the Assistant. The selection arrives as a **Selected Text** chip above the input, which is sharper than turning the Assistant loose on the whole document.
The Assistants from the Libra web app are available in the Word add-in too — the ones you built, the ones colleagues shared with you, and Libra's own library. Picking one in Word applies exactly what it applies in the web app: its prompt instructions, its knowledge documents, and the research sources it was configured with. See [Assistants](/en/features/assistants/introduction) for what goes into one.
## Pick an Assistant
Pin the two or three you actually reach for — the NDA checker, the clause rewriter, the jurisdiction researcher. Beats scrolling the firm-wide list on every document.
## What an Assistant brings into Word
An Assistant configured with **Knowledge** documents is the one that pays off most in Word: it reads the document you have open against the reference material it already carries — your standard template, the house style guide, the relevant statute — so the analysis is consistent from matter to matter without you attaching anything.
Research sources come across too. If the Assistant has research sources pre-set, selecting it switches **Research** on with exactly those sources; switch back to a plain model and the selection clears again. You can still change the selection afterwards in the **Research** panel, and it holds for the rest of the chat — until you switch Assistant, which reapplies that Assistant's sources or clears them.
Pinning sorts within the Assistant's own section only — **My Assistants**, **Shared Assistants** and **Libra Assistants** always render in that order, so a pinned Shared Assistant rises to the top of its own group rather than the top of the list.
