# Introduction

Embed Trueyy's live interview-integrity monitoring directly into your own ATS or hiring product.

The **Trueyy SDK** lets you embed live interview-integrity monitoring - real-time AI-tool detection, transcript analysis, and risk scoring - directly into your own ATS or hiring product. Your interviewers and candidates never leave your app.

## Two packages, one integration

Trueyy ships as a small set of packages. A full integration uses **two** of them: one on your backend, one on your frontend.

  <Card title="@trueyy-sdk/web" href="/web" description="React frontend. Drop-in <TrueyyMonitor>, <TrueyyJoin>, and <TrueyyReplay> components plus hooks for a fully custom UI." />
  <Card title="@trueyy-sdk/web-core" href="/web-core" description="Advanced. Framework-agnostic browser client + Helper bridge. Use directly only for non-React or vanilla-JS integrations." />
</Cards>

<Callout title="Which do I install?">
Building a normal React integration? Install **`@trueyy-sdk/node`** on your server and **`@trueyy-sdk/web`** on your frontend. `@trueyy-sdk/web-core` is pulled in automatically as a dependency of `@trueyy-sdk/web` - you only install it directly for non-React frontends.
</Callout>

## How it fits together

1. Your **backend** (`@trueyy-sdk/node`) creates an interview and its rounds, then mints a short-lived (5-minute) browser token per round and role.
2. Your **frontend** (`@trueyy-sdk/web`) takes that token, opens a secure WebSocket to Trueyy Cloud, and renders the live monitoring UI.
3. Trueyy streams risk pulses, transcript segments, and window analysis to the interviewer in real time, and delivers **webhooks** to your backend as the session progresses.
4. After the round, your backend pulls the final **report**.

Your master `tk_live_` API key never touches the browser - see [Architecture](/architecture) for the full token-flow diagram and security model.
