Linguix vs. Writer.com: Grammar Checking Benchmarking Analysis

The Linguix team has conveyed a series of benchmarking tests comparing the performance of the two popular grammar checkers, Linguix and Writer.com*.  You can check our benchmarking against Grammarly here.

To check these tools in action, we used two datasets of 1515 English sentences, part of which contained grammar mistakes and the rest of which were correct. All in all, the test datasets featured several thousands of grammar mistakes to detect. 

Below are the results of the performance analysis. 

*Pro/Premium versions of Linguix and Writer.com were benchmarked.
