Glarity

Glarity is a browser extension that summarizes and translates web content using large language models. It summarizes YouTube videos, including timestamped key moments, FAQs and subtitle translation, and also summarizes web pages, PDFs, emails, Google search results and Twitter pages. Users can chat with the content and apply custom prompts to pull out specific information. The extension also offers side by side and full page translation, translation of selected text in pages and PDFs, image translation, voice translation, quick replies in Gmail, and an AI writing assistant for drafting and improving articles, emails and social replies. AI Chat is offered across more than ten models. Glarity says it runs on ChatGPT, GPT 4o, Claude 3.5 and Gemini, and users can connect their own OpenAI key. It targets people who read and research across languages and want shorter versions of long videos and documents. Glarity installs on Chrome, Edge, Safari, Firefox and Opera, and the vendor describes the core extension as free and ad free. A paid Glarity membership, described as more stable and faster than the user's own OpenAI key, supports models including GPT 4o, Claude 3.5 Sonnet, Gemini 1.5 Pro and LLAMA 3, with monthly or annual billing in selectable currencies. The membership price is not shown on the pricing page text, and the vendor notes the plan is in testing and may change.
