Dear Anne,
I agree with you that Grammarly has accomplished something truly remarkable with their small team. I first became familiar with Grammarly when their team and I were tenants in the same business center back in Kyiv a few years ago. I have found their tool to be incredibly useful, and I now make it a habit to check my writing with Grammarly whenever I'm working on an article.
Thank you once again for reaching out, and I hope you have a great day ahead :)
