I used OrfoGramka with a teacher's license, which is provided for free upon registration on Dnevnik.ru. With this tool, you can check essays and other student works, as well as working documents. However, checking anything else without payment is prohibited, otherwise the license can be revoked. Students can also use the program, but on a paid basis (although discounts are available for them). OrfoGramka effectively identifies mistakes, highlights them, and provides explanations, making it very useful in the educational process. I asked students to send their essays electronically, after which I checked them using the program. We then discussed all the mistakes in detail, reading the comments. For each mistake, there is a rule of the Russian language in the knowledge base with many examples, and the program also offers automatic corrections.
