I sometimes use this service to check the originality of text. I most often turn to Etxt when I need to know the exact uniqueness percentage and identify all matches. Etxt performs this task very accurately and surpasses other similar services. For example, in a case where text.ru showed 100% originality, Etxt reported 96% and indicated 4 different sources with found matches. I only deduct one point for the annoying captcha that I have to enter 5-6 times when checking a text of 2000 characters. It takes time and is a bit irritating, so I don't use it very often.
