My grammar was bad ever since preliminary schools, I always had trouble writing articles, letter, and applications. I used Grammarly in the beginning as the free version which grants me access to basic grammar and spelling corrections. it solved many mistakes i made while writing emails and applications instantaneously. the speed of the tool is incredible and fixes grammar issue on the got. later i needed professional standards in articles so i switched to the premium version and its really awesome cool you get access to a whole new level, here you can type the article on the web and it highlights all your errors which can be fixed with simple clicks. the greatest thing about Grammarly is the pricing. its actually free to use so everyone can access it. the tool is available in all platforms including windows, mac, and mobile devices.as well as an addon available for Microsoft Word.
Grammarly doesn't support many sites which is extremely irritating, it doesn't support quora, discord, google drive etc. the premium version isn't really affordable to all. it only highlights the errors and sometimes it doesn't show how to fix it.
it is a free tool. give it a try
