# Semplu - AI-Powered Text Enhancement Platform

> AI-powered Android app that seamlessly integrates text enhancement into all applications. Create professional text with one tap – directly from the text selection menu.

## Overview

Semplu transforms Android into an AI-powered writing assistant. The app provides two intuitive access methods: system integration through the native text selection menu and a smart floating button. With six specialized enhancement modes (General, Professional Email, Social Media, Casual Message, AI Prompt, Image Generation), Semplu optimizes every text for its specific context. The hybrid architecture combines Native Android for system integration with React Native for the user interface.
