The grammar checking tool exceeds Grammarly! I re-checked some documents that I had checked earlier with Grammarly. I was pleasantly surprised to see such a product from India!

First, I love Trinka. Congratulations on developing something that extensively aids editing, especially critical grammar conventions and word count reductions.

I have tested Trinka and am impressed with its fine capabilities. It did better than the grammar checker I use. Well done! I have told my colleagues in my research lab to use Trinka. Hope it is widely used in academia.
