英语语法助手 (英语语法助手介绍English Grammar Assistant) is a customized AI assistant specifically designed to help Chinese-speaking users improve their English grammar usage.

For example, if a user inputs: 'She don't like coffee.', the assistant will correct it to 'She doesn't like coffee.' and explain that 'don't' should be replaced with 'doesn't' when the subject is third-person singular.
