Grammar Checker Extension

This application is a browser extension designed to enhance text editing by identifying and highlighting grammar errors, misspelled words, and blacklisted terms on web pages. It provides the following features:

Grammar and Spelling Error Detection: The extension scans the text on a webpage and highlights grammar mistakes and misspelled words using an external grammar-checking API.

Customizable Blacklist and Whitelist: Users can add words to a blacklist (to flag them as errors) or a whitelist (to ignore them during checks). These lists are stored and synchronized across devices.

Interactive Tooltips: When hovering over highlighted words, the extension displays a tooltip with suggestions for corrections or additional information.

Context Menu Integration: Users can right-click on words to quickly add them to the blacklist or whitelist.

Error Navigation: The extension provides functionality to navigate through errors on the page and scroll to specific ones.

Real-Time Updates: Changes to the blacklist, whitelist, or text content are reflected immediately, ensuring that the highlights stay up-to-date.

Periodic Rechecks: The extension periodically rechecks the page for new errors, ensuring that dynamic content is also analyzed.

This tool is ideal for users who want to improve the quality of their writing or enforce specific language rules on web pages.
