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.

I know the grammatical rules of English, but…
“I’m worried about if the wordings are natural.”
“I can’t come up with the exact sentence to express my idea.”
“I want to know the natural flow as the rest of this text.”
“I’m not confident in my academic writing.”
