Using Armbrain During a Live Client Call

4 min read

The Setup

Have Claude open on a second screen or in a split window during calls. This isn't about staring at a screen instead of listening - it's about having a safety net for the moments when memory fails.

Before the call starts:

"Switch to Acme"
"Prep my meeting with Acme"

Scan the brief. Note the open items and the suggested talking points. Now you're anchored.

Quick Searches Mid-Conversation

Someone asks a question you can't answer from memory. Type while they're still talking:

"When did we decide to change the homepage layout?"
"What was the outcome of the LinkedIn campaign?"
"What did Sarah say about the Q3 budget?"

Armbrain does a semantic search and returns the relevant memory with context. You glance at the result, respond naturally, and the client never knows you needed a prompt.

What works well to search for:

  • Decisions ("when did we decide X?")
  • Campaign results ("what happened with the email campaign?")
  • Stakeholder positions ("what did the CEO say about the rebrand?")
  • Timelines ("when is the product launch?")

What doesn't work mid-call:

  • Complex multi-step queries (save these for after)
  • Anything that requires you to read more than 2-3 lines

Real-Time Note Capture

Capture important moments immediately. When you hear something worth remembering:

"Quick note: CEO wants to double the ad budget for Q3"
"Quick note: Sarah is leaving in June, replacement TBD"
"Quick note: Board meeting moved to May 15"

Quick notes are fast and unstructured. Type them in 10 seconds and get back to listening. You'll organize them later if needed.

For decisions and commitments, be more specific when you have a natural pause:

"Remember as a decision: Approved the new brand colors - navy and coral"
"Remember as a commitment: I'll send the competitive analysis by Thursday"

The distinction matters. Decisions get surfaced in future meeting preps. Commitments get tracked as action items with accountability.

The Post-Call 3-Minute Capture

The call ends. You have 3 minutes before the next one. This is the most important part.

Capture the things you didn't type during the call:

"Quick note: Acme team seemed frustrated about the website timeline"
"Remember: New stakeholder introduced - Tom from product, reports to Sarah"
"Remember as a commitment: Client will send the analytics access by end of week"

Then capture anything you want to keep private:

"Internal note - confidential, do not share: Sarah hinted she's unhappy with the CEO's involvement in marketing decisions"

Sensitive and internal CMO memories stay with you. They don't appear in client-safe handoff exports or restricted team views. Use explicit markers such as confidential, eyes only, or do not share for observations, political dynamics, and strategic assessments.

When to Use It vs. When to Be Present

Call guidelines:

Use ArmbrainJust Be Present
Fact-checking a date or decisionEmotional or difficult conversations
Capturing a critical commitmentOne-on-one relationship building
Looking up a stakeholder's preferenceCreative brainstorming sessions
Quick note on something you'll forgetWhen the client can see your screen

For sensitive calls (budget cuts, team changes, performance concerns), close your laptop and be present. Capture everything after the call instead.

If you're on video and the client can see you typing, be transparent about it: "I'm noting that in our system so it doesn't get lost." Most clients appreciate that you're documenting what matters. It signals that you take their business seriously.

The Pattern Over Time

After a few weeks of using Armbrain during calls, something shifts. You stop worrying about forgetting things. You ask better questions because you're not trying to hold context in your head. You make bolder recommendations because you can instantly verify what was tried before.

The client notices too. They stop starting meetings with 10 minutes of "let me catch you up on what happened." They know you already know. That's the trust that keeps engagements going.

Practical Tips

  • Keep the Claude window small. You need to glance, not read. If you're reading paragraphs mid-call, you're doing it wrong.
  • Use quick notes, not full store_memory. Speed matters during calls. Classify later.
  • Mute yourself when typing. Keyboard clicks on a call sound like you're not paying attention.
  • Prep before, capture after. The call itself should have minimal Armbrain interaction - maybe 2-3 quick notes and 1 search.
  • Don't search for things you can just ask. If the client is right there, ask them. Save the search for things you should already know.
