Echoo vs Grammarly

Grammarly is the most well-known writing assistant in the world, and for good reason - it has spent years refining its grammar checking, building a massive user base, and creating a polished experience with inline suggestions that appear as you type. For users who want a zero-setup grammar checker that works in browsers and major desktop apps, Grammarly is a proven choice. However, Grammarly comes with significant trade-offs that make Echoo worth considering. Privacy is a key consideration: Grammarly is a cloud service, so text you check is processed on its servers (per Grammarly's documentation), which may be a concern for anyone handling sensitive text. Echoo lets you use local AI models that never send data off your machine, or connect to your own API key so text goes directly to your chosen provider without any intermediary. Cost is another factor - Grammarly Premium runs $12/month, and many of its best features are paywalled. Echoo Pro is $6.99/month, nearly half that, and you can try 10 free credits with no API key or credit card. Power users can skip subscriptions entirely by bringing their own API key in the free BYOK mode. Beyond grammar, Echoo offers capabilities Grammarly simply does not: voice dictation in 25 languages, translation between any language pair, code review and refactoring, file processing from Finder, and unlimited custom AI commands via a community marketplace. Grammarly is narrowly focused on English writing improvement, while Echoo is a versatile AI text transformation platform. For pure grammar checking with inline suggestions, Grammarly has the more polished experience. For everything else - privacy, cost, versatility, voice, code, translation - Echoo is the stronger choice.
