About Offline Basic Spell Check
Offline Basic Spell Check is a lightweight Chrome extension that provides a simple spelling review tool directly inside the extension popup, without requiring an internet connection.
The extension allows users to paste or type text and instantly check for potential spelling mistakes using a small built-in dictionary that works entirely offline. Suspected misspellings are visually highlighted, and basic word suggestions are provided to help users review and correct their text.
The interface is designed with a modern, clean layout focused on clarity and ease of use. Users can manually run the check or enable automatic checking while typing. Additional options allow ignoring words written in all capital letters.
Offline Basic Spell Check does not access websites, does not read browsing data, and does not connect to any external services. All processing happens locally inside the popup. The extension does not collect, store, or share any user data and does not require any special permissions.
This tool is intended for quick, basic spelling review and is not meant to replace full language-processing or advanced grammar-checking software.
