Grammarly is not meant to be a tool to make poorly written articles better when the discrepancies come in language barriers. While it can help, it would be synonymous with spreading a thin layer fresh concrete over a cracked and warped foundation. It may look great as it dries, but the structure is garbage.
Word by word, things may look great. Sentence by sentence, things may seem okay. But when you zoom out to the paragraph level, these small issues cause problems with the big picture. The basic Grammarly approach won't help with semantics.
The best tips I can suggest to become stronger at writing English is:
- When you watch English television, turn on the captions and read them.
- Get your ass off the Internet and read some actual books. Nobody proofreads forum posts and YouTube comments.
- Create conversational threads on here, and respond to everyone with full sentences.
- Write articles and stories, and then read your writing out loud to see if it makes sense.
- Take articles in your native language and translate them into English.
- Proofread, proofread, proofread.
- Find someone better than you and get them to look over things you write.
Grammarly + Microsoft Word grammar checking/spell check + Hemingway will improve a lot. But if you use tools as a crutch, your improvements will be 10% of what they could be if you immerse yourself instead.
That is how I started. I got an old Windows 95 computer for my 8th or 9th birthday and it was so slow that it would only run Office. I spent my weekends from ages 8 to 12 chopping firewood, doing chores around the house with my parents and sister, and writing stories about tornadoes and FBI field agents and abandoned theme parks and everything in between. I put my friends in the stories and then had them read them.
Practicing constantly eventually got me to the point where I was winning essay contests.
I went to Disney World for a week because I won an essay contest.
I've got a shit-ton of trophies in the closet from spelling bees and speech contests and essay contests I won on the state level.
I got an all-expenses paid trip to Washington DC because I wrote a killer paper on how we should capture stories of WWII vets before they all die.
I spent my last two summers of high school on college campuses getting "the college experience" and learning advanced mathematical concepts... because I wrote a convincing application letter.
I got my college education completely paid for because I wrote a shit-ton of essays my senior year of high school and won over a dozen small scholarships as a result.
And now I make a six-figure income between writing I do online, for clients, and in my day job.
Knowing how to write is (to me) the second most important real-world skill you can have. The first being the ability to communicate and filter your thoughts into spoken words and actions.
