Despite the current diversity and inclusion initiatives in the academic
community, researchers with a non-native command of English still face
significant obstacles when writing papers in English. This paper presents the
Langsmith editor, which assists inexperienced, non-native researchers to write
English papers, especially in the natural language processing (NLP) field. Our
system can suggest fluent, academic-style sentences to writers based on their
rough, incomplete phrases or sentences. The system also encourages interaction
between human writers and the computerized revision system. The experimental
results demonstrated that Langsmith helps non-native English-speaker students
write papers in English. The system is available at https://emnlp-demo.editor.
