# ChurnKit Overview

> Real-time churn prediction and risk scoring for SaaS products.

## What is ChurnKit?

ChurnKit is a behavioral churn prediction engine. It ingests events from your product, scores each user's churn risk in real time, and fires webhook alerts when users cross configurable risk thresholds — so your team can act before they cancel.

## How risk scoring works

ChurnKit's scoring model considers:

* **Recency** — how recently the user was active
* **Frequency** — how often they use core features
* **Depth** — breadth of feature adoption
* **Trajectory** — whether engagement is trending up or down
* **Plan signals** — trial expiry, downgrade history, support volume

The model outputs:

| Field            | Type                          | Description                 |
| ---------------- | ----------------------------- | --------------------------- |
| `score`          | `number`                      | 0.0 (safe) → 1.0 (churning) |
| `tier`           | `'low' \| 'medium' \| 'high'` | Human-readable risk band    |
| `signals`        | `string[]`                    | Reasons driving the score   |
| `recommendation` | `string`                      | Suggested action            |

## Typical integration flow

```
User signs up → identify()
User logs in → event('session_started')
User uses feature → event('feature_used', { feature: '...' })
Cron / webhook → score() or watch() alerts your team
Team reacts → email, in-app nudge, CS outreach
```
