GrammarElf is a product developed by Triptipedia (the online collaborative encyclopedia of travel tips).
This project started as a small internal Triptipedia tool to fix mistakes on the website. But when we realized that many major websites had plenty of spelling and grammar mistakes too, we decided to make it a standalone tool that could be used by anyone.
GrammarElf's suggestions for text improvement are generated thanks to the awesome LanguageTool.
