FAQs
How does GrammarPeace remain free while using advanced AI models?
GrammarPeace is free because it's open-source and operates on a 'bring your own API key' model. Users connect their personal API keys from providers like Anthropic (Claude) or OpenAI, paying only for their direct usage of these AI services, which is typically very low cost.
What kind of privacy does GrammarPeace offer?
GrammarPeace is designed with privacy in mind. It has no servers, performs no tracking, and collects no user data. Your text is sent directly from your browser to the AI API provider (Claude or OpenAI) using your own API key, ensuring your information remains private.
Can GrammarPeace be used for languages other than English?
Yes, GrammarPeace supports translation for over 15 languages. While its primary grammar checking is robust for English, the translation feature allows users to work with and understand content in a wide array of languages, making it versatile for multilingual communication.
