# Welcome to Lucent

> Session replay and product insights that show you exactly what happened.

Lucent records real user sessions in your web app, stores them securely, and
turns them into signals you can act on — rage clicks, dead clicks, broken flows,
and AI‑generated insights that explain *why* a session went sideways.

## How Lucent works

1. **Record** — drop `@lucenthq/sdk` into your app. It uses rrweb under the
   hood to capture DOM mutations, clicks, inputs, console output, and network
   calls, with a privacy‑first default that masks all text.
2. **Ingest** — events are batched in the browser and flushed to Lucent's
   ingest API. Sessions are stored immutably and processed asynchronously.
3. **Analyze** — Lucent detects rage clicks, dead clicks, and navigation
   friction, then runs an AI analysis pass over each session to surface
   the issues that matter.
4. **Act** — review signals in the dashboard, share links with your team,
   or pipe them into your issue tracker.
