# Call Coach 

A live sales-call assistant. It listens to the conversation, sends it to TypeSafe Jev after every sentence, and shows the rep what to do next with a confidence score. 

This is a work in progress and a demo of Jev capabilities. Feel free to fork it and modify it. Or just message me if you want to make any changes. I am also open to pull requests as well for making improvements. Shoot me a DM if you need anything

## What you need


- Node.js 18 or newer (no packages to install)
- A TypeSafe API key
- Chrome or Edge for voice input. Other browsers can use the typed input instead.

## Run it

macOS or Linux:

```sh
TYPESAFE_API_KEY=your_key node server.mjs
```

Windows (PowerShell):

```powershell
$env:TYPESAFE_API_KEY="your_key"; node server.mjs
```

Then open http://localhost:3000 and allow microphone access when the browser asks.

To try it without talking, press **Play sample call**. It feeds a scripted conversation through the real API, one line every few seconds.

## Using it on a call

1. Press **Start listening**.
2. Switch between **Customer speaking** and **I'm speaking** as the conversation goes back and forth, or press **S** on the keyboard.
3. Watch the gauge. It shows the buying score (0-100), the current buying stage, and a confidence label.
4. The card below shows the suggested next step and coaching tips.
5. Press **D** or the **Mark done** button to dismiss a suggestion for a few minutes.
