Overview
A free, lightweight, non-invasive AI grammar and proofreading extension that runs 100% on-device for total privacy and offline use.
Proofly is a free, privacy-first Chrome extension that brings professional-grade writing assistance directly to your browser using Chrome's Built-in AI technology. Unlike other writing assistants that send your data to the cloud, Proofly runs 100% locally on your device, ensuring your keystrokes and personal information never leave your machine. KEY FEATURES: 🔒 100% Private & Offline • Zero data transmission - everything stays on your device • Works completely offline after initial model download • No tracking, no telemetry, no account required ✨ Intelligent Proofreading • Powered by Chrome's built-in Gemini Nano AI model • Instantly catches spelling, grammar, and punctuation errors • Fixes capitalization, missing words, and preposition usage 🚀 Seamless Integration • Works on input fields, textareas, and contenteditable elements • Lightweight and non-invasive UI • Native-feeling underlines and correction popovers • Dedicated sidebar for reviewing all issues at once ⚙️ Customizable Experience • Toggle specific correction types (e.g., check grammar but ignore capitalization) • Custom keyboard shortcut to check a chunk of text • Auto-correct and manual trigger modes Why Proofly? Most grammar checkers require you to trust them with your private emails, documents, and messages. Proofly eliminates this risk by leveraging the AI capabilities already built into your Chrome browser. It's the secure, free, and open-source alternative for anyone who values privacy. Note: Proofly requires Chrome 141+ and a device capable of running Chrome's built-in AI models.
