Korrektno

Korrektno is a Russian-language online service that provides automated grammar, punctuation, and style checking for Russian texts. The platform was launched in 2007 by a team of linguists and software engineers from Moscow. It was designed to support students, journalists, and professionals in producing error-free Russian prose. The system combines natural language processing algorithms with a large corpus of annotated texts to identify typical typographical mistakes, syntactic errors, and stylistic anomalies. Users can submit text through a web interface or by installing a browser extension that highlights issues in real time.

The service offers free basic checks for short texts, with a premium subscription that provides in-depth analysis, contextual suggestions, and integration with popular word processors. Korrektno also maintains a community forum where users discuss rule clarifications and receive feedback from language experts. Over the years, the platform has updated its engine to accommodate changes in Russian orthographic reforms and to include a speech-to-text module that expands accessibility.

In academic and professional circles, Korrektno is cited as a valuable tool for improving textual quality and as a teaching aid in language courses. By 2020, the service had processed millions of documents and had integrated with major publishing houses in Russia. As of 2024, the platform remains active, with ongoing developments aimed at enhancing machine learning models and expanding multilingual support.
