## Description

**ChatGPT Glarity** is a powerful, open-source Chrome extension that leverages ChatGPT to summarize content from YouTube videos, Google search results, webpages, and PDFs. It supports multi-language summaries, interactive AI chats, FAQs, and market-ready subtitles for YouTube content. This extension also offers seamless translation services with multiple engines, side-by-side comparison, and translation of screenshots and images. 

Beyond summarization, Glarity acts as a writing assistant, helping draft emails and social media posts, while supporting easy switching between ChatGPT 3.5 and 4 models. It respects user privacy by operating entirely within the browser without storing data on servers or displaying ads. Glarity provides a comprehensive AI-powered browsing experience free of cost, enhancing information comprehension and global accessibility.
