Spell Fixer

🚀 Overview

Spell Fixer is a Chrome extension (Manifest V3) that performs offline, real-time spell checking in text fields, textareas, and rich-text editors on any website. No remote API, no user data collection — everything runs locally.

• Website-wide, per-page correction highlights
• Real-time misspelling underlines and suggestions
• Keyboard-friendly and accessible architecture
• Supports custom words via chrome.storage.local
