Your AI sales engineer
Know their stack.
Hold the technical call.
VoiceVocab learns your product and the prospect's tech stack, then feeds you the right explanation — before, during, and after every call.
Heard on the call
Prospect: "…we mostly run Kubernetes on EKS for the ingestion plane."
Detected
Kubernetes on EKS
Managed control plane over AWS. Pods auto-scaled across AZs — their team doesn't operate masters.

The technical conversation you keep losing
“You nodded in the meeting. You had no idea what they meant.”
“You read their stack doc three times and still couldn't talk about it.”
“Your rep froze when the prospect asked how it works.”
Battlecards give you lines. Docs give you familiarity.
Neither trains you to perform on the call.
How it works
One copilot, the whole call
Upload what you have
Your product docs, PDFs, internal notes. VoiceVocab reads them and builds a knowledge base scoped to the company you're meeting with.
Get briefed before the call
A prioritized list of technologies likely to come up, with short briefs on each: what it is, why it's used, key terms, common pain points, questions to ask.
Get nudged during the call
VoiceVocab listens with you. The moment a technology gets mentioned, you see a one-line explanation so you never have to nod along.
What it does
Built around the call, not the curriculum
Five capabilities working together — every one of them tied to a moment in the conversation.
01
Knowledge ingestion
Drop in PDFs, documentation, and notes about your product and the prospect. VoiceVocab builds a focused knowledge base for the meeting at hand.
02
Technology discovery
We surface the technologies the prospect uses, the ones related to your product, and the ones most likely to come up on the call — ranked by what you actually need to know.
03
Pre-call briefs
For each technology: a 90-second plain-English brief covering what it is, why teams use it, key terminology, common pain points, and the questions worth asking.
04
Real-time call assist
Our Chrome extension listens to the call with you. The moment a technology lands in the conversation, a one-line explainer appears in the side panel, with no recordings nor audio leaving your device.
05
Post-call recap
Right after the call, you get a short technical debrief: which technologies came up, which ones you didn't quite land, and what to brush up on before the next one — so you walk into every follow-up better than the last.
