The first thirty seconds of a call decide a surprising amount. If you open with "So, what can I do for you?", the person on the other end has to repeat everything they already told your business. If you open with "Last week you asked about moving your appointment to mornings, and you mentioned your budget had changed; shall we start there?", they know you were listening, and the conversation starts in the right place.
The difference between those two openings is preparation. Preparation used to mean scrolling through call notes, emails and old messages for ten minutes before every call, which most people do not have time to do. A pre-meeting brief does that work for you: it reads what came before and tells you, in a minute's reading, what matters for the conversation you are about to have.
This article explains what a useful brief should contain, why it has to cover a person's whole history rather than the last call, and how Cypher M, the Cypher LM copilot, prepares briefs before calls and meetings, including the ones on your calendar. The examples come from two kinds of work where a good opening matters most: sales calls and recruiter calls.
Why the first minute of a call matters
People remember how a conversation made them feel long after they forget the details. A prospect who has to explain their situation for the third time feels like a ticket number. A candidate who is asked about a notice period they already disclosed feels that the recruiter is not paying attention. Neither of them will say so, but both will be a little less willing to say yes at the end of the call.
The opposite is also true. When you open with something specific from a previous conversation, you signal that the relationship has continuity. The person relaxes, skips the recap and gets to the point. Calls become shorter and more useful for both sides, and the person is more likely to trust the next thing you say.
Most teams know this, and most try to prepare. The trouble is the volume. A salesperson may have eight calls a day; a recruiter may have fifteen. Each one has a history scattered across call logs, emails and notes written by different people. Ten minutes of preparation per call is two hours a day, which nobody has. So preparation quietly shrinks to a glance at the contact's name.
There is a second problem: preparation done by hand is uneven. The calls you prepare for are usually the ones you already think are important. The ones that turn out to matter, the quiet prospect who was ready to buy, the candidate who mentioned a competing offer in passing, are the ones you walked into cold.
What a useful brief contains
A brief is not a transcript and not a call log. It is a short, structured answer to one question: what do I need to know before I speak to this person? The briefs Cypher M prepares are organised around the parts that change what you say:
- What they want. The outcome the person is looking for, in one or two sentences.
- Summary. What has happened in your conversations so far.
- Open items. Questions still unanswered and requests still pending.
- Objections and concerns. Hesitations they have raised, such as price, timing or fit.
- Promises. What your business said it would do, so you can confirm it was done.
- A suggested opening. A specific first line that picks up where the last conversation ended.
- Next steps. What a good outcome for this call would look like.
Each part earns its place. Open items and promises stop you from being caught out: there is nothing worse than a customer asking about a quote your colleague promised and you not knowing it exists. Objections let you prepare an answer before the subject comes up. The suggested opening is optional, but it is often the most useful line in the brief, because it turns preparation into a first sentence.
What a brief should leave out
A good brief is also defined by what it does not include. It does not repeat every pleasantry, every scheduling message or every detail of a call that went nowhere. It does not guess at things nobody said. If there is no history, a good brief says so plainly instead of padding the space. Cypher M will tell you when a contact has no calls with your agent yet, or when the calls it found have no transcript or summary to brief from, rather than inventing context.
Why the whole history matters, not just the last call
Most tools that summarise "the last call" miss the point. Relationships unfold over several conversations, and the important detail is often in an older one: the budget mentioned in the first call, the decision-maker named in the second, the concern that came up once and was never resolved.
Cypher M builds each brief from all of the person's past calls with your voice agent. That sounds simple, but it depends on knowing which calls belong to the same person. People call from different numbers, give a slightly different email the second time, or reconnect after a dropped web call. Cypher LM links these signals: the same phone number, the same email, the same browser returning to your website widget, a reconnected call, and the bookings those calls made. A caller who mistyped their email on the first call and gave the correct one on the second is treated as one person, not two strangers.
If you connect Google with read access to Gmail, briefs can also draw on your recent emails with that person. That matters for sales and recruiting, where much of the relationship happens by email between calls. A brief that knows the prospect replied yesterday asking for a revised proposal will suggest a very different opening from one that only knows about last week's call.
The result is a brief that reflects what your business actually knows about a person, not just what the most recent conversation contained.
Sales calls: a brief in practice
Consider a sales call with a prospect, Daniel Brooks, who first spoke to your voice agent two weeks ago about upgrading his company's plan, then called again last week with questions about onboarding.
Without a brief, the account executive opens with a general discovery question and spends ten minutes rediscovering what the agent already captured. With a brief, they know before saying hello that Daniel wants to move his team over before the end of the quarter, that he is worried about the time onboarding will take, that the agent promised to send an onboarding outline, and that the last conversation ended with him asking who else he should involve.
The suggested opening might be: "Daniel, thanks for making time. Last week you were asking about onboarding timelines; I have the outline we promised and a suggestion for who to bring in from your side." The call starts with the open item, addresses the concern before it becomes an objection, and moves to next steps.
Sales teams also benefit from the objections section in particular. If a prospect raised price twice in earlier calls, the brief surfaces that, and the account executive can prepare a clear answer instead of being caught off guard in the final minutes.
Recruiter calls: a brief in practice
Recruiting has its own version of the same problem. A candidate, Rachel Adams, called your agent about a role on Tuesday evening, answered the screening questions, mentioned a four-week notice period and said she preferred hybrid working. She called back on Thursday to correct her email and ask whether the salary range was negotiable.
The recruiter calling her back on Friday has a brief that brings both calls together: what she wants, her notice period, her working preference, the open question about salary, and the fact that the agent said a recruiter would discuss pay on the next call. The suggested opening addresses the salary question directly, because that is what Rachel is waiting to hear about.
Briefs help with client calls too. Before a briefing with a hiring manager, a summary of agreed requirements, open questions and promised shortlists means the recruiter starts where the last conversation ended. Our article on AI voice agents for recruiting agencies covers the rest of that workflow.
From brief to live suggestions
A brief prepares you for the opening. During the conversation itself, Cypher M can keep helping.
When you start a session, Cypher M follows the conversation and offers short suggestions as cards: an answer to a question the person just asked, a next step to propose, a way to handle an objection, or a piece of information from your business's knowledge. You choose Use or Dismiss on each one. Nothing is said on your behalf; the suggestions are there for you to use in your own words.
There are a few ways for Cypher M to follow the conversation. For a Google Meet call, Cypher M can join the meeting as a guest and hear everyone, or you can share the Meet tab with its audio from your browser. For a phone call at your desk, Copilot can listen through your computer's microphone in Chrome, Edge or Safari; Firefox does not support the browser speech service it uses, but you can still type what the customer says to get suggestions. Suggestions work in English, Urdu or a mix of both.
Playbooks shape what Copilot suggests. A playbook is short guidance for a common situation: how your team handles a price objection, how to explain your onboarding process, what to say when a candidate asks about remote work. Copilot follows the playbooks you have switched on. Every suggestion your team actually uses is collected in the Suggestions library, grouped by playbook, which over time becomes a record of what good answers sound like at your company.
Making briefs better over time
A brief can only be as good as the conversations behind it. Three habits make a noticeable difference.
First, let your voice agent capture details consistently. If your agent asks every caller the same core questions, such as what they need, their timeline and the best way to reach them, those answers appear in every brief in the same shape. Our article on writing a knowledge base your voice agent can use covers how to set this up.
Second, close the loop on promises. A brief lists what your business promised; it is only useful if someone checks those promises are kept. Follow-ups agreed on calls and meetings are collected in one list, so your team can tick them off before the next conversation, and the next brief reflects what has actually been done.
Third, write playbooks for the situations you meet most. A brief tells you that a prospect is worried about price; a playbook tells Copilot how your team answers that concern. Together, they turn a good opening into a well-handled call.
How this works in Cypher LM
There are three places you will meet a brief in Cypher LM.
- In Contacts. Every caller who shares a phone number or email becomes a contact. Opening a contact shows their history across calls, and Copilot can prepare a brief from those calls before you ring them back.
- When you start a session. In Copilot › Sessions, choose Start session and pick who you are calling. If they have spoken to your AI agent before, Copilot shows the brief at the start of the session, then follows the call with live suggestions. If the person is new, there is no brief, but suggestions still draw on your playbooks and business details.
- On your calendar. In My Calendar, opening a meeting shows its details alongside the client's AI brief, and a banner shows your next meeting with a live countdown and a one-tap Join button. Choose Onboard Cypher M on a meeting and Cypher M prepares the brief, emails it to you, and joins the Google Meet automatically shortly before it starts.
When Cypher M joins a Google Meet, it asks to join as a guest, like any other attendee, and someone in the meeting admits it. The Cypher M Chrome extension can admit it for you and shows hints inside Meet. When the session ends, you get a summary and follow-ups.
The brief gets better as your agent handles more conversations. Every call the agent answers adds to the history Cypher M reads, so the more your voice agent is used, the more useful your briefs become.
| Where | What you see | Best for |
|---|---|---|
| Contacts | The person's call history and a brief before you call back | Returning a customer's or candidate's call |
| Copilot › Sessions | Brief at the start, then live suggestions during the call | Sales and recruiter calls from your desk |
| My Calendar | The brief in the meeting popup; Onboard Cypher M emails it and joins | Scheduled Google Meet meetings |
Frequently asked questions
Where does the brief get its information?
From every past call the person has had with your voice agent, linked across phone numbers, emails, reconnected calls and bookings. If you connect Google with read access to Gmail, it can also use your recent emails with that person.
What if the person has never spoken to our agent?
Then there is nothing to brief on, and Cypher M says so rather than inventing context. You can still start a session, and live suggestions will draw on your playbooks and business details.
Does Cypher M join Zoom or Microsoft Teams meetings?
Not today. Cypher M joins Google Meet meetings as a guest. For calls on other platforms or by phone, you can start a session and let Copilot listen through your browser's microphone.
Will the person know Cypher M is in the meeting?
Yes. Cypher M joins as a visible guest and has to be admitted to the meeting. We recommend telling attendees at the start that you are using an assistant to take notes and help you prepare.
Can my whole team use briefs?
Yes. Teammates you invite in Settings can use Copilot according to their role, and suggestions they use are shared in the Suggestions library.
Walk into every conversation prepared
A brief does not make the conversation for you. It gives you the context a good colleague would whisper in your ear before you pick up the phone: what this person wants, what you promised, and where to start. Done for every call, not just the important ones, it changes how your customers and candidates experience your team.
