Is Fix Grammar safe?

Low risk

Quick Grammar Fixer & AI Proofreader sends selected or typed text to a Vercel-hosted grammar API when you check grammar.

The extension monitors page text selection and copies selected text into its side panel. When you click Check grammar, it sends the selected or typed text as a writing-assistant prompt to vercel-open-api-proxy.vercel.app/api/grammar.
