ORFO is a proofreading system for spelling, grammar, punctuation, and style, designed mainly for Russian-language document work. It offers its own editor, ORFO Online, downloadable Windows and macOS software, and Microsoft Office integration. The Professional package adds Russian, English, and Ukrainian spelling checks to Russian grammar and style checking, while the wider package range suits users who need publishing tools or additional European-language dictionaries.

Pricing is organized around perpetual licenses with software and dictionary updates included for one year. The paid-only range starts at 1980 with Professional, which includes Russian, English, and Ukrainian spelling, Russian grammar and style checking, Microsoft Office integration, and unlimited ORFO Online access during the update-subscription period. Professional Plus adds Adobe InCopy and InDesign support, additional dictionaries, and word-form search and replacement in Microsoft Word. Maximum adds spelling checks for German, French, Spanish, Italian, and Portuguese. Separate macOS packages provide comparable functionality, including a Plus edition with Adobe support and additional dictionaries.

Its main advantage is the depth of its Russian-language toolkit: user dictionaries can accept all word forms, while synonym, antonym, related-word lookup, grammar references, and dictionary collections support editing beyond basic spell checks. Office and Adobe integrations make it relevant to document and publishing workflows, but its focus is narrower than that of a broad multilingual writing assistant. ORFO is a sensible choice for Russian-heavy Office work, especially when desktop proofreading and linguistic reference tools matter. Users seeking a free tier, AI features, or a wider platform strategy should consider alternatives.
