In order to improve text processing, this study introduces a multilingual AI-powered writing assistant with four main features: text production with translation, text summarisation, text paraphrasing, and grammatical correction. The grammar correction tool improves grammatical accuracy while maintaining writing style and supporting many languages. The LLaMA-implemented text summarisation function allows for organised summaries in a variety of formats (paragraphs, bullet points) and lengths (short, medium, and long). The text paraphrase feature uses DeepSeek to provide rewordings that are both styleadaptive and contextually appropriate. Using Microsoft's API, the text generation with translation feature first converts content into English before applying DeepSeek to enhance its coherence and fluency. This hybrid technique is a useful tool for multilingual communication and content creation since it guarantees high-quality text processing across a variety of languages.
