Language Scanner

Introduction

Advanced language scanner to detect users language, distance and names on a Sim. With the hud menu, you can easily filter by language. Useful to find who speak your language or who speak the language of your choice. Can be used with a translator as an addon or as a standalone tool.

- Optimized: tested with more 90 users, low memory, safe and secure
