Chat is where most of your work in Libra starts. The spring release redesigns the chat input around three ideas: a single Tools dropdown for everything you can attach or create, Chat modes for picking the right amount of reasoning for the question, and an @-mention picker for referencing anything in your work.

Type @ mid-sentence, not just at the start. The picker filters as you type. @nda finds your NDA template; + Enter inserts.

The @-mention picker

The fastest way to attach context, without leaving the input.

Type @ anywhere in your prompt

The picker opens with recent items, grouped by type: Assistants, Workflows, Documents, Reviews, Discoveries.@-mention picker open in chat input with recent items grouped by type

Filter by typing

As you continue typing, the picker filters live by name.

Pick with arrow keys + Enter, or click

The mention is inserted as a pill in your prompt. Send the message; the referenced item is now part of the chat’s context.
@ works anywhere in the prompt, not just at the start. “Compare the confidentiality terms in @NDA-baseline against this draft” is a valid prompt.

Working with responses

Below every response, the toolbar gives you the standard set of actions.
ActionWhat it does
CopyCopies the response with formatting preserved.
ExportSaves the response as Word, Excel, or an email draft.
RegenerateAsks Libra for a different version of the answer.
Send emailDrops the response into a new email in your default mail app.
For the structured answer side, including citations, sources, and the cited-sources panel, see Citations & sources.

Long-running responses keep going in the background

Chat responses, especially in Deep Thinking or Research mode, can take a minute or two to finish. You don’t have to wait — leaving the chat lets the response continue streaming in the background, and Libra notifies you when it’s done.
What you’ll seeWhen
Toast notificationPops in from the corner of the screen the moment a background chat finishes.
Notification-center entryA row in the Updates tab of the bell icon (top-right), with the chat name, a snippet of the answer, and a link straight back to the chat.

Send a long Research prompt, then jump to another project to keep working. The bell turns active when your answer is ready; click the row to jump straight back to the chat at the right scroll position.
The notification-center entry is per-session and per-device — refreshing the page or signing out clears in-session entries that haven’t been opened. Server-backed notifications (sharing, license changes, etc.) survive reloads. Notification center bell open with a background chat completion entry under Updates

Tips for getting good answers

“Review the contract” is too vague. “Review the contract for non-compete clauses that may be unenforceable under California law” is something Libra can act on. Treat each prompt like a brief to a junior associate: context, scope, and outcome.
“Under German employment law”, “per New York state contract law”, “in a Swiss commercial context”: these phrases narrow the answer dramatically.
“Provide your analysis as a numbered list of issues”, “Format as a comparison table with columns Risk, Clause, Recommendation”, “Draft this as a partner-facing memo”. Format requests almost always pay for themselves.
Don’t try to nail it in one prompt. Start broad, then narrow. “Now focus specifically on Section 4.2”, “Give me a more formal version”, “Explain the reasoning behind your third point.”
Treat citations the way you’d treat a junior’s case cite: open the source and confirm it says what’s claimed. Verified citations (clickable, linked to a database) are more reliable than unverified ones (plain text). See Citations & sources for how Libra distinguishes them.
For questions that need case-law or statute citations, switch the Research toggle on and pick the relevant databases. See Research mode.

Press in an empty input to recall your last prompt, then tweak and re-send instead of retyping. Shift+Enter drops a newline; Enter sends.
