The gap
Users need a grammar and spellcheck tool that integrates seamlessly across Google Docs, Outlook, and Word. Current tools like Private Grammar Checker - Harper and Grammarly fail to provide consistent functionality across these specific platforms, especially within Google Docs.
What people say
“The extension is only available in English, with no other language options, making it pointless. Furthermore, it doesn't work in Google Docs, making it doubly pointless. It works well, checking text directly on the page, replacing the now-paid Language Tool.”
