People Also Ask

  • Can grammar checkers handle different languages?
    Yes. AI-powered grammar checkers like Wondershare PDFelement supports multiple languages. However, how many languages each one supports varies. There are also tools that support only English and its variations. Thus, when choosing a grammar checker, consider whether you will need to scan non-English text or not.
  • Can grammar checkers replace human proofreading?
    Not entirely. You can use AI grammar checkers for quick scans. However, because they have limitations, you'd still want the help of human proofreaders for more professional work. For example, hiring an expert to proofread your 10,000-word-long novel is better than using a free AI grammar checker.
  • What should I do if a grammar checker’s suggestion seems incorrect?
    If the detected word is an industry-specific jargon, the grammar checker may flag it as incorrect. You can ignore the suggestion or add the word to the dictionary.
