Abstract: Krit Text Suite is an advanced word analysis mobile application built using Flutter, offering users real-time, in-depth insights into word meanings and linguistic properties. By integrating multiple API endpoints via RapidAPI, the app fetches and categorizes word-related data, including definitions, synonyms, antonyms, pronunciation, syllables, examples, and rhymes, presenting the results in a structured and user-friendly interface. The application ensures seamless real-time data retrieval with intelligent error handling, allowing it to skip non-responsive APIs while displaying successfully retrieved information. Secure authentication is implemented via Firebase Authentication for OTP-based phone number verification and AWS Lambda for email-based login and signup, with MongoDB Atlas managing user credentials and search history. Krit Text Suite is designed for linguists, students, writers, and educators, offering an intuitive and efficient platform for vocabulary expansion and language learning. The app is hosted on Firebase for web accessibility, ensuring scalability and security.
