Glarity is a browser extension that embeds ChatGPT-generated summaries alongside search results, videos, and web pages. It supports summarizing content from Google, YouTube, Yahoo News, PubMed, PMC, GitHub, NewsPicks, Nikkei, Bing, Google Patents, Bilibili, and arbitrary web pages. It integrates with both the official ChatGPT interface and OpenAI API (GPT-3.5-turbo, text-davinci-003) for generation, and offers side-by-side translation and Gmail quick-reply features built on top of the same AI summarization capability.
