Two ways to reach REX
Both are the same underlying assistant:- The Ask REX button opens it as a side-sheet drawer over whatever you’re currently looking at.
- The REX item at the top of the left-hand navigation opens it as a full, dedicated page.
How it works
When you ask REX something, it decides which tools it needs, calls them in sequence, and reports back in the chat. You’ll see a live “REX is looking up…” style status as it works. REX is context-aware. If you open it while looking at a specific room, it already knows what you’re looking at and will use that as its starting point. REX runs on a bounded number of steps per turn, so it won’t spiral into an endless loop. It will either finish the task and report back, or ask you a clarifying question if it’s genuinely unsure. It only bases its answers and actions on data it actually retrieved through a tool, so it doesn’t make up facts, contacts, or figures.Capabilities

Updating your CRM
Drafting and sending email
What REX knows
- Everything inside your deal rooms: content, structure, and engagement or viewer activity
- Your connected CRM data (HubSpot, Salesforce, or Attio)
- Signals automatically generated from meetings, CRM syncs, and room activity
- Your content library, including structured summaries of what each asset covers. See Asset intelligence
- Your org’s users, templates, statuses, and labels
- Its own conversation history with you
- Live public web results, when it searches
- What room you’re currently viewing, so it can ground its answer in context
What REX can’t or won’t do
- It won’t act on data it hasn’t actually retrieved, so it won’t invent contacts, numbers, or sources.
- It won’t work without an available usage credit balance for your organisation.

REX drafts the email and hands it back for approval. Nothing goes out until you say so
How different roles use this
Sales reps
Sales reps
- “Summarise where this deal stands and what’s blocking it”
- “Draft a follow-up email to the champion after yesterday’s call”
- “What CRM fields are out of date on this deal?”
- “Find me a one-pager about our security posture for a healthcare buyer, and add it to this room”
- “Set up a mutual action plan for this deal with the standard onboarding steps”
- “Update the HubSpot stage to Negotiation”
- “What can I do to unblock [deal name]?” REX will connect a stakeholder’s stated blocker to a specific asset, such as a roadmap doc showing a requested feature is already planned, and offer to add it to the room or send it directly.
- “How do I improve my chances of closing [deal name]?” REX will point to the specific stakeholder holding things up, say an economic buyer who’s still defensive, and can offer to build a new asset tailored to what that person needs to see.
Onboarding & CS teams
Onboarding & CS teams
- “Summarise where this onboarding stands and what’s blocking go-live” pulls together room activity, CRM, and signals the same way it would for a sales deal.
- “Draft a check-in email to [admin] about the stalled integration step” gets drafted grounded in what’s actually happened in the room, and still asks for your approval before sending.
- “What’s the engagement been like on this account this month?” is a fast way to check adoption without digging through analytics yourself.
- If REX seems to be missing context on an account, check the same things you would for a sales deal: is the CRM connected, and is a note-taker integration wired up for check-in calls?
Managers
Managers
- Ask REX directly: “What’s blocking [deal name]?” or “Summarise the last two weeks of activity on [deal name]” to prep for a review without digging through the room yourself.
- Use REX to spot CRM hygiene gaps across a rep’s pipeline, such as missing fields or stale stages, and flag them before your next 1:1.
- REX’s recommended actions on a deal double as a coaching prompt. You can ask a rep why a recommended action wasn’t taken.
