What is Glarity?
Glarity is a browser extension that summarizes YouTube videos, search results, articles, PDFs and emails, and translates whole web pages side by side. It runs on ChatGPT, Claude, Gemini or your own OpenAI key and is open source.
Summaries work across languages, so you can read the gist of a foreign video or page in your own. Translation covers full pages, selected text, PDF text and images, and an AI reader lets you chat with a PDF or web page.
A writing assistant drafts articles, emails and social replies, and Glarity AI Chat gives access to many models with a long context window and image generation. The extension is available for Chrome, Edge, Safari, Firefox and Opera.
