What Langsmith Editor Realizes
Langsmith Editor has various assistance features for helping your writing. For example, the rewriting feature suggests fluent, academic-style sentences to writers based on their rough, incomplete phrases or sentences.
This editor encourages interaction between human writers and the computerized system, where systems give diverse suggestions, and writers get inspiration to put their ideas to words.
Langsmith Editor gives you feedback on vocabulary choice, sentence structure, or fluency, along with correcting apparent errors. That is, Langsmith Editor is an “all-in-one” system that includes various assistance tools for writing. This makes your writing experience efficient.
As one of the use cases, Langsmith can be used for post-editing the drafts created by, for example, machine translation systems.

I myself use it whenever I write or revise papers in English.
I routinely use the Langsmith Editor to check if there is more natural wording. I always recommend the Langsmith Editor to my students in my laboratory.
