Our verdict on StyleGuard
StyleGuard is a cloud-based writing style and proofing tool for writers, editors, journalists, publishers, and communications teams. It checks spelling, word usage, capitalization, punctuation, terminology, abbreviations, and hyphenation against published references and custom rules. Editorial teams can use it across Microsoft Office, Google Docs, web browsers, Adobe InDesign, WordPress, Blogger, and other supported environments, with API access for content-management and editorial systems.
Pricing is organized by dictionary or style-guide subscription rather than one universal plan. The Brazilian Portuguese plan costs $49.99 per year and includes a Brazilian Portuguese dictionary, custom entries and shared dictionaries, browser plug-ins, Microsoft Word integration, and support for Windows, macOS, and Chromebook. The Financial Times Style Guide plan costs $89.99 per year and includes Financial Times guidance, British English, custom entries and shared dictionaries, browser plug-ins, and Microsoft Word integration. The Canadian Press Stylebook and Caps & Spelling plan costs CAD 125 per user per year and includes Canadian English, custom entries and shared dictionaries, browser plug-ins, and Microsoft Word integration.
Its strongest fit is an organization that needs a shared editorial system rather than basic spelling correction. StyleGuard Manager supports shared guides, custom terminology, and proofing-usage statistics, while suggested corrections include accept and ignore controls. Microsoft Word, Outlook, PowerPoint, Google Docs, Chrome, Firefox, Safari, InDesign, WordPress, and Blogger integrations broaden its working-environment coverage, and the API supports CMS and editorial-system integration. Teams that need formal reference-based rules, brand terminology, or publishing workflows should consider StyleGuard; individuals seeking a free checker or AI writing features should look elsewhere.
