Chat with your Library

Ask natural-language questions and get cited answers grounded in your own documents.

May 21, 2026

Chat with Library is Vulgate's flagship feature: a conversational interface that pulls relevant passages from your documents, generates an answer, and footnotes every claim back to the source.

Starting a chat

  1. Click Chat in the sidebar.
  2. Type your question in the input box at the bottom.
  3. Press Enter (or click the send button).

The first response usually arrives within a few seconds. Follow-up questions in the same chat keep the conversation context — you can refer to "that document" or "the part you just mentioned" without re-explaining.

What questions Chat is good at

  • Summaries. "Summarize what the council said about Eucharistic adoration."
  • Comparisons. "How does this author treat the topic of mercy compared to the previous one?"
  • Citations. "Find me three quotes that argue for X."
  • Synthesis. "What are the main arguments across all the documents in this Collection?"
  • Explanation. "What does the term 'aliturgical' mean in the context of these texts?"

For pure passage lookups (no synthesis), Search is faster — see How to query your Library.

Reading the response

Each response includes:

  • The answer — written in clear prose with numbered citations (¹, ², ³).
  • A References section — every numbered citation listed with the document title and section heading. Click any reference to open the source passage in a new tab.

See Understanding citations for everything about how citations work.

Choosing which Libraries to search

Use the Libraries dropdown above the input to pick which Libraries Chat retrieves from. By default it covers all the Libraries you have access to (private and Organization). See Choosing libraries in Chat.

Attaching files mid-chat

Click Attach (paperclip) next to the input to attach a PDF, image, or short text file to your message — useful when you want the AI to consider a one-off file. Attachments are not added to your Library. See Attaching files mid-chat.

Saving and sharing

  • Copy answer — copy the answer text and its references to your clipboard.
  • Share the chat — copy a public read-only link anyone with the URL can open.
  • Pin — save the chat to your Saved Queries.

Privacy

Chat history is private to you by default. See Is my data used to train AI? for how chats and documents are processed.
