The Assistant is the default chat interface in the Lucio sidebar. Use it to ask questions about the open document, request edits, summarise sections, extract obligations, or redraft clauses.
Asking Questions
Type any question in the chat bar. The Assistant reads the open document and responds in context.
Every response includes numbered citations linked to the exact clause or paragraph the answer is drawn from. Click any citation to jump to that location in the document.
You can also select text in the document and ask a question specific to that selection.
Editing the Document
Ask the Assistant to redraft a clause, tighten language, update defined terms, or make targeted edits. The Assistant returns the suggestion in the chat with two buttons.
Show: highlights where the change will be applied.
Apply: inserts the change.
When applying, choose from:
Apply as tracked change
Apply (no tracked change)
Apply with comment
Apply as tracked change with comment
Attachments
Attach reference documents to give the Assistant additional context for your query. For example, a term sheet, a precedent contract, a regulatory filing, or any document you want Lucio to read alongside the open Word file.
Click the attachment button in the chat bar to add files. You can attach from:
Your desktop (drag and drop or browse)
OneDrive Personal
OneDrive for Business
SharePoint
NetDocuments
Supported file types: .docx, .doc, and .pdf.
Attachments stay scoped to the current chat. Start a new chat and you can attach a different set of files.
Prompt Enhancement
If you are not sure how to phrase a query, press Tab in the chat bar to enhance your prompt. Lucio takes your short prompt and expands it into a structured one. Review the expanded version, edit if needed, or revert to the original.
Prompt Library
Access the prompt library from the bottom toolbar. It has three tabs.
Featured: prebuilt prompts curated by Lucio.
My Prompts: prompts you have created.
Starred: prompts you have bookmarked.
To create a prompt, click New Prompt, give it a title, write the prompt, optionally enhance it, and save.
Model and Personalisation
Both are accessed from the profile button at the top of the sidebar.
Model picker: select the AI model you want to use. Models are available from OpenAI, Anthropic, and Google. Switching models can change the tone, depth, and reasoning of responses.
Personalisation: describe your preferences for how Lucio should make edits and write comments. Save your preferences and Lucio will adhere to this style across every chat.
