Abstract: This paper presents a new Vietnamese spelling correction system that allows users to correct spelling errors in their text. Our system is an interactive writing assistant that integrates advanced technologies in natural language processing to (i) identify spelling errors and (ii) replace those errors with their corrected version. To the best of our knowledge, our system is the first Vietnamese spelling correction tool that interacts with the users via Web Interface, Microsoft Word and Chrome extensions to provide the best user experience. We also perform automatic and human evaluations to demonstrate the effectiveness of our system. Our system is publicly available at https://grammar.vinai.io/.
