Recently bought Linguix yearly deal on Appsumo.
To be honest I don't know whether your tool corrects grammar mistakes or not.
What it does is correcting commas, full stops and spelling mistakes. That's all
Yesterday I wrote a 2000 words of content and corrected all the grammatical errors using Linguix.
But I again checked the Linguix corrected content on Grammarly it spotted and showed more errors.

I don't know whether it is an good alternative to grammarly tool?
I have bought premium version of linguix so that it can identify most of the errors, but premium version is same as free version.
In that case why should i downgrade to free version?
Or you're developing this tool with more features?
Kindly clarify my issue...
