## Features

- **Model Selection** — Searchable bottom sheet grouped by endpoint, model comparison mode
- **Agents** — Marketplace with search and categories, MCP server configuration
- **Conversations** — Paginated list with date grouping, tags, search, rename, archive, delete, share, fork, duplicate, export/import
- **Presets & Prompts** — Save/load chat presets, prompts library with @mention insertion

- **Accessibility** — Semantic headings, content descriptions, 48dp touch targets, live regions
## Server Setup
The app works with any standard LibreChat server. During onboarding, you'll enter your server URL (e.g., `https://chat.example.com` or `http://192.168.1.100:3080`).
### Required Configuration
Add the following to your LibreChat server's `.env` file:
```env
# Safety net for native app clients.
# The app sends a browser User-Agent to pass the uaParser middleware,
# but if it ever fails to parse, this prevents ban point accumulation.
NON_BROWSER_VIOLATION_SCORE=0
```
Without this setting, the server's violation system may accumulate ban points against the Android client if the User-Agent check fails, eventually locking the account out.
### Notes
- **Registration** — The app respects your server's registration settings. If registration is disabled server-side, only the login form is shown.
## Building from Source
**Requirements:** Android Studio, JDK 17+
```bash
./gradlew assembleDebug
```
The debug APK will be at `app/build/outputs/apk/debug/app-debug.apk`.
For a release build:
```bash
./gradlew assembleRelease
```
### Tech Stack
- Jetpack Compose + Compose Navigation
- Hilt (dependency injection)
- Ktor Client with OkHttp engine
- Kotlinx Serialization
- Room (cache), DataStore (preferences), EncryptedSharedPreferences (tokens)
- Kotlin 2.1.0, compileSdk 35, minSdk 26
