I think Linguix is a tool with potential, and from the basic operating principle very pleasant.

However, I will probably get a refund, because at least in my constellation "German language", the "websites I use" and the "sentences, as I formulate them", takes more effort to ignore the wrong error messages than to find the useful ones. Linguix does detect mistakes I make, but also some that are not mistakes at all.

For instance, at the beginning of a sentence, capitalized words are marked as errors and again and again, there are complaints of spelling errors which they are not. On the other hand, it does not find obvious spelling mistakes like capitalized adjectives or non capitalized nouns.

All in all, I don't want to say that the tool is bad and certainly has potential. I wish Linguix much success in its further development. At the moment, it's not enough for me.
