Hints in the Reedach panel and marks right in the text.
Reedach checks Russian text while you write in the block editor. It finds bureaucratese, clichés, filler and evaluative words, time parasites, heavy syntax, common mistakes, colloquialisms and typography slips, explains what is wrong and suggests how to say it simpler.
The hints themselves are in Russian: they explain Russian text. The interface is in English; translations, Russian included, come from translate.wordpress.org.
This plugin checks style only. Spelling and morphology need a Reedach server, see the project site.
Hints are a guide, not a rule. The check works by a dictionary and simple rules, so it sometimes errs and does not replace an editor.
Reedach is an open project: source code on GitHub. The plugin is under GPLv2 or later; the bundled Reedach core and rules are under the MIT license.
Reedach проверяет русский текст прямо в редакторе блоков: канцелярит, штампы, вода, оценочные слова, паразиты времени, тяжёлый синтаксис, частые ошибки, просторечия, типографика. Объясняет, что не так, и подсказывает, как сказать проще. Проверка идёт в браузере автора, текст никуда не отправляется.
