This project aims to develop a writing assistant. It has been designed to check for spelling and grammatical errors, analyze sentiment, detect plagiarism, and translate text from one language to another. This tool, using Natural Language Processing (NLP), analyzes text and provides appropriate error-free recommendations. Working as a writing assistant, this project assists users with their day-to-day activities, whether an informal letter to a friend, an important project report, or an online blog post. Social networks and community forums have become one of the most used platforms to communicate with people who may be from a different region speaking a foreign language. It consists of a massive amount of data where positive content from one’s point of view may not be the same for others. In such situations, a writing assistant may act as an extra set of eyes to catch common errors and improve writing.
