## What is Nosmai Moderation?

Nosmai Moderation is a content safety SDK that runs entirely on the user's device. It checks images, recorded video, chat text and the live camera for unsafe content, and returns a clear verdict your app can act on. There is no cloud round-trip, so frames and messages never leave the phone.

You install one SDK, initialize it with a license key, and call a small set of methods. All models ship inside the SDK, so checks keep working offline after the one-time setup.

## What it moderates

| Surface | What it does |
| --- | --- |
| Image | Check a single photo |
| Video | Sample and aggregate a recorded clip |
| Text | Check a chat message or comment |
| Live camera | Real-time, per-frame moderation |

It detects adult / NSFW imagery and unsafe text (profanity, toxicity, hate, harassment, threats).

## Why on-device

- **Privacy**: user content never leaves the device, which helps with compliance.
- **Latency**: no network call per check, so results are immediate.
- **Cost**: no per-request cloud bill for moderation.
- **Offline**: works without connectivity after the one-time license check.
