User insights about the spell check feature

Reviewers feel that ProWritingAid's spell check is reliable and essential for writers, catching many errors that other tools might miss. They appreciate its customization options for different English variants and the ability to add words to a personal dictionary. Users find it fast and accurate, though some mention it occasionally flags proper names and academic references incorrectly. They also note that it works well in conjunction with other spell check tools for comprehensive proofreading.
“Does a good job with spelling. It does allow for additions to a personal dictionary which is extremely helpful. There are times when alternate spellings are available that can be grammar issues (like UK English v US English) that is a touchpoint for a user that is better when they have experience and knowledge of the differences to make a better choice based on the recommendation.”

“I like the spell check in general but I do use it in conjunction with Grammarly free and just use my own knowledge to accept or deny suggestions. Most of them are ok but sometimes I disagree with suggestions. One thing that I do find really helpful is that it can help me write in US or UK English as I'm an Australian writer. ”

User insights about the spell check feature

Reviewers indicate that Grammarly Business's spell check feature is highly accurate and efficient, automatically correcting errors and providing suggestions in real-time. They find it especially helpful for fast typists and non-native English speakers. Users appreciate its integration with various platforms and its ability to handle both American and British English. They mention that it saves time, enhances professionalism, and reduces the need for manual proofreading. However, some users note occasional inaccuracies with technical terms and slang.
“The spell check is another great feature in the Grammarly suite of tools. At times one tends to make spelling errors with the most common words and tends to oversee them. Thanks to the spell check tool, these mistakes are notified to the user, and she/he can make the necessary amends. This tool is also very helpful for words one is unfamiliar with and makes a spelling error.”
